Oceanic + Phone Dive Housing Available!

The best camera is the one you have with you

Traditionally, if you wanted to take photos or videos underwater on your diving adventure, you needed a setup like I have in the pictures to the left. A large Ikelite housing, a high end camera, and multiple external flashes. This will still give you the absolute quality images, but is expensive and cumbersome for travel. In the last few years, several products have come to market allowing you to take the camera you carry with you every day, your phone, with you diving or snorkeling allowing you to have pictures where they are most available to you to share and post. We now offer on Seethesearx.com, as authorized Oceanic dealers, the Oceanic + housing, the perfect companion for your prescription dive mask. 

The Oceanic + Dive Housing, compatible with iPhone 15 Pro Max iPhone 14 iPhone 12 iPhone Xr iPhone 15 Pro iPhone 13 Pro Max iPhone 12 Mini iPhone X iPhone 15 Plus iPhone 13 Pro iPhone 11 Pro Max iPhone SE (3rd Generation) iPhone 15 iPhone 13 iPhone 11 Pro iPhone SE (2nd Generation iPhone 14 Pro Max iPhone 13 Mini iPhone 11 iPhone 14 Pro iPhone 12 Pro Max iPhone Xs Max iPhone 14 Plus iPhone 12 Pro iPhone Xs

This is one of my favorite pictures I have taken while diving- I captured this turtle on my iPhone 14 Pro Max in a dive case in St. Martin about 2 years ago. Depth – approximatley 60 feet underwater 

Overview of the Oceanic + Housing

The Oceanic+ Dive Housing is meticulously designed to provide robust protection for high-end phones, ensuring they perform flawlessly in the depths of the ocean. Constructed from durable materials such as corrosion-resistant metals and reinforced polycarbonate, this housing is engineered to withstand the pressure and elements encountered underwater. Its ergonomic design allows for easy handling and operation, even in challenging underwater environments where visibility and dexterity may be compromised.

The primary function of any underwater housing is to provide optical clarity while protecting the phone. The Oceanic+ Dive Housing excels in this aspect with precision-engineered ports and and lens that maintain the camera’s autofocus capabilities and ensure sharp, clear images. Advanced coatings and materials minimize glare and distortion, preserving the natural colors and details of the underwater world. This clarity is essential for capturing the vivid hues of coral reefs, the graceful movements of marine life, and the intricate textures of underwater landscapes.

In terms of camera functionality, the housing has a built in app for depth and color correction, ability to use all the camera’s lenses, and ability to quickly share photos when topside (keep in mind even though you have your phone with you underwater, cellphone signal is lost within several feet of the surface).

Dive computer functionality

The Oceanic + Dive Housing has a dive computer app built in, however, this does have a subscription fee if desired (the app fee is shared with the app on the Apple Watch if you have that subscription). The subscription is NOT required for the camera functionality, but is an added feature available for those that might want it (and one less piece of equipment have to travel with).

Conclusion

There is no question the easiest way to take photos and video underwater is with your phone and a compact dive housing. These housings provide an easy compact way to bring your phone underwater on reefs, wrecks, or wherever your diving adventures take you. These housings are even great for snorkeling. The camera quality on phones has increased gigantically over the last few years, and while a DSLR/mirrorless set up will produce the highest quality photos available (and we can help you build a set up like that if you wish) in terms of space and cost, these phone housings cannot be beat. The Oceanic + housing costs $489.96 and ships free with your prescription dive mask order. If you would like to purchase one separately, feel free to reach out.

Earth’s Tectonic Plates with Prescription ScubaPro Dive Mask

Scuba Diver in dry suitin clear water in Iceland with a scuba pro d mask with lenses installed by See the Sea RX

Diving in Iceland

Iceland, the land of fire and ice, is renowned for its breathtaking landscapes, from towering glaciers to majestic waterfalls. While I spent much of last year in England, I was able to find a deal on last minute flights to Iceland with the idea of exploring Iceland’s hidden gem for adventure seekers: scuba diving between the tectonic plates in water a degree or two away from freezing. While my flights were inexpensive, Iceland as a whole is expensive (something to definitely keep in mind). Packed with my scuba pro d mask and prescription lenses installed in our lab in Houston and a bunch of warm clothes, I was able to get a quick feel for Iceland’s tourism. The trip was a great experience, but I am not in a rush to return (I am, primarily, a spoiled warm water diver). In this blog, I will fill you in on my trip- things to do in Iceland, and some considerations for dive masks in cold water.

Just for context, my trip was in January/February 2024.

Scuba Diving Between Tectonic Plates

One of the most exhilarating experiences Iceland has to offer is diving at the Silfra Fissure in Thingvellir National Park. There are two main options: Snorkeling in a dry suit (no certification required) or you can dive through the fissure. You are required to have both a dive certification as well as a dry suite certification to participate. The water hovers around 35 degrees year round.

The outing to Silfra cost near $300 including transport from the hotel as well as all equipment. You can bring your own equipment if you wish, but be sure your regulators are serviced and intended for cold water use. I did bring my prescription scuba mask as well as the Sealife phone case which I have been using more than my traditional dive camera set up on these quick trips. All the pics I took were on my Iphone (14 pro max at the time) using the Sealife case.

 

The dive is short, about 30 minutes and led in small groups with a certified instructor.

 

Overall it is a unique once in a lifetime experience.

Cold water prescription scuba mask concerns


Some divers contact us wondering if our prescription dive masks will work in near freezing or freezing water temperatures. As you can see with my mask, they hold up well. A few things you can do to prevent damage to the lenses: Try to acclimate the mask to surrounding/water temp before submerging. Going between extreme temperatures can cause the laminate to fracture.

Non diving Iceland Activities

While scuba diving between tectonic plates is a highlight of any trip to Iceland, the country offers an array of other activities in which to indulge:

  1. Golden Circle Tour: Discover Iceland’s iconic sights, including the mighty Gullfoss waterfall, the geothermal wonders of Geysir, and the historic site of Thingvellir National Park. I did not have time to take part in one of the Golden Circle Tours, but they remain one of the more popular options.

 

  1. Glacier Hiking: Strap on crampons and traverse the otherworldly landscapes of Iceland’s glaciers. Guided tours provide insight into glaciology while offering stunning views of ice formations.

 

  1. Whale Watching: Set sail from Reykjavik or Husavik for a chance to spot majestic whales, including humpbacks, orcas, and blue whales, in their natural habitat.

 

  1. Northern Lights Hunting: During the winter months, chase the elusive aurora borealis across Iceland’s dark skies for a mesmerizing display of dancing colors. I missed out on seeing the northern lights the one night I went out. The tour does offer a voucher to try again within a year or two, but it is unlikely I will be back. This was also not a favorite of mine as the first half hour of the tour was picking up other tourists at other hotels (and thirty to forty five minutes of drop offs at the end) and then driving around in a mini bus to locations which may offer the chance to view the lights. The tour staff were friendly, but I would probably find another way of doing this if I was to go again. 

 

  1. Relax in Hot Springs: Unwind in Iceland’s geothermal pools and hot springs, such as the iconic Blue Lagoon or the secluded Secret Lagoon, surrounded by stunning landscapes. I chose to go to Sky Lagoon which is a bit newer and located a little closer to the center of Reykjavik. My pictures of Sky Lagoon are seen on the right.

Prescription Dive Masks for Strong Plus (Farsighted) Lenses

My glasses are thick- can I even go diving?

For those of us with very strong prescriptions or optical corrections, when we learn to dive there is excitement and then a moment of panic about how we are going to be able to see while underwater with a snorkeling or diving mask. There is good news. See the Sea can make dive masks in any prescription (yes even yours), and we have not turned away a single diver since we started for prescription strength limits (including lenses with over 20 diopters).

I have previously written articles on prescription scuba diving mask considerations for those with strong prescriptions, but in today’s article, I want to focus on those with strong plus prescriptions.

Due to varieties in masks: depths of lens pockets or lens size, certain masks work better for stronger prescriptions than others, specifically when talking about corrective lenses (bifocals or distance lenses) for those with spherical equivalents over +4.00. The wrong mask choice can lead to the lenses contacting the diver’s face and even causing pain. As a reminder, you can order a mask with lenses from us, or you can send us your mask to have lenses installed. Either way, if your prescription is over +4.00, these are the factors to consider in a dive mask:

 

  • Good lens pocket depth. We want the lenses to have some distance from the face to minimize the risk of lenses contacting the divers face.

  • Smaller overall lens size. The smaller the lenses, generally the thinner we can produce the prescription lens for your dive mask.

  • Twin lens dive masks generally work better for strong plus prescriptions than single lens masks.
The Scubapro D-Mask is my top choice for divers with very strong prescriptions.

Best Dive Masks for strong farsighted lenses

Here are our recommendations for masks that we sell, that work very well for strong plus lenses:

  1. Scubapro D- Mask (my top choice and the mask I currently dive). Click here for my full review of the mask.
  2. IST M200 (Aluminum frame mask for small to regular fit faces)
  3. IST M100 (Aluminum frame mask for average faces to slightly wide)

diving Masks that we don't sell but are good options

Scuba diving mask with light pink frame and higher strength prescription lenses.
IST M200- a mask that we sell that works well for strong plus lenses. This goggle has a fairly strong minus (nearsighted) correction installed.

Here are masks that we don’t sell on our website, but make great options for high plus lenses (if you own one of these, you can definitely send them in to us to have high plus lenses installed) :

  • Aqua Lung Reveal X2 Mask
  • Mares Viper Mask (ultra low volume free diving mask which allows for a small and relatively thinner lens)
  • Sherwood Targa Mask
  • Cressi Big Eyes Evolution Mask
  • Tusa Ceos Mask

Great dive masks (that are bad for thick plus lenses)

We love single lens masks- but in general masks like these that place the front glass closer to the diver's eyes are not great for strong plus lenses as the lenses may come close to the divers face. In this example has moderately weak distance lenses installed which are thin enough to prevent this problem.

Here is a list of popular dive masks, that we can install prescription lenses into, but are NOT good options for strong plus lenses (still great option for other lenses):

 

  • Cressi F1 Frameless Mask
  • Aqua Lung Micro Mask
  • Scubapro Synergy 2 Mask
  • Atomic Aquatics Venom Frameless Mask
  • Mares X-Vision Ultra Liquidskin Mask
  • Oceanic Shadow Frameless Mask
  • Tusa Freedom HD Mask
  • Hollis M1 Frameless Mask
  • Tusa Paragon S Mask
  • Atomic Aquatics Frameless Mask
  • Scubapro Solo Mask
  • Hollis M3 Mask
  • Mares X-Free Mask

The above are all quality dive masks (some of which are even available on our site) which work well for a lot of prescriptions- however they are not good options for those with strong plus lenses.

If you are just snorkeling, our full face snorkel masks also work well with all prescriptions, even very strong ones.

Just a few reminders: Our made to order lenses can correct for strabismus and astigmatism (prism and cylinder). No matter your prescription, we can make a dive mask for you, but mask selection is more important for those with strong plus corrections. Feel free to give us a call or email if you have questions about selecting a mask, or whether your mask will work for your prescriptions.

Single Lens Dive Mask and Prescription Lenses

Single lens dive masks such as the scuba pro gorilla mask, atomic aquatics venom (& venom frameless) have become increasingly popular with divers due to their increased field of view as well as offering comfort for some divers with more prominent nasal bridges which may be compressed with twin lens dive masks. We frequently get calls from scuba divers and snorkelers asking if we can make prescription lenses for their single lens dive masks or get a dive mask from us with single lenses and a prescription. The short answer is yes, and in this article, I am going to discuss some of the confusing nomenclature regarding prescription dive masks (such as single lens vs single vision), different single lens options, and some of the advantages (and disadvantages) of getting prescription lenses such as bifocals, single vision, and readers put into a single lens dive mask.

What is the difference between a single lens and a twin lens dive mask?

This one is pretty fairly straight forward. Below I have two examples of masks with prescription lenses installed. One is the Atomic Aquatics subframe with custom st-35 bifocals (the st-35 bifocals have a slightly larger reading area for those that do more macro work such as photographers. You can read my article on the different bifocal options for dive masks here)- the other is a Tusa Single Lens Dive Mask (with an Anti-UV coating).

Atomic Subframe- a TWIN lens dive mask with custom oversize bifocals installed by See the Sea RX
A TUSA single lens dive mask with custom single vision lenses made in our lab. We do get questions rom divers about installing lenses with dive masks with coatings, and this is not an issue for us as seen here.

The Tusa mask has one single piece of front glass, while the Atomic Subframe has two lens pieces separated by a nasal bridge. Some single lens masks are marketed as “frameless” consisting of just the skirt and the lens, and no frame portion (such as the atomic frameless 1 and 2).

We can install lenses in both, as you can see in the above images. Aesthetically, I prefer the look of twin lens masks with prescription lenses as the prescription lenses will be made per eye and installed in the dive mask; however, functionally there is no difference.

You can get both single and twin lens dive masks in clear and black skirts (I talk more about differences in skirt colors in my article on picking the right mask for prescription lenses here, and a video on YouTube we uploaded here).

What is the difference between single lens and single vision?

This one is a little more confusing for some divers not used to these terms. Single lens refers to the dive mask construction and single vision relates to vision correction. Single Vision lenses correct for a single distance, typically distance for nearsighted folks like me. Here is my Scuba Pro D-Mask with prescription lenses (single vision) before a recent dive in Sint Maarten.

Here are the different type of prescription lenses:

Single Vision– Correct for one vision distance. Typically distance. Can correct for astigmatism, include prism correction for those with strabismus, and can be made custom to your exact prescription.

Bifocal Lenses- These lenses correct for two distances. As we age, our lenses lose elasticity, and it becomes more difficult for our eyes to accommodate for near vision and reading. Those of us that wear glasses to correct for distance (nearsighted mostly) will over time likely need a multifocal correction of some sort.

Reading Lenses– Reading lenses are a special type of single vision lenses that we produce and are installed in the bottom of the dive mask for divers that have developed presbyopia (the loss of lens elasticity discussed in the bifocal description), but who do not need distance correction (or only minimal distance correction that they do not want to correct). Single lens masks are a favorite for divers who want readers, due to the oversize readers we can produce for them. Check out my article on custom prescription readers for the Atomic Venom mask here.

Other considerations for single lens dive masks:

Single lens dive masks have oversize lenses, which makes them particularly useful for one type of prescription lens we make- the franklin bifocal. The franklin bifocal is a fully custom bifocal where we make two lenses per eye (one for distance one for near) and we can make the percentage size of each two completely to order. For example, those that do primarily video or photo work and want up to 80% of their lens space used for near vision, we can do that. We frequently use the Atomic Venom Frameless for this purpose.

Reading Lens Options for Scuba Masks

Trouble seeing your gauges?

As we age, we lose the elasticity of the lens of our eye, which makes focusing on closer objects more difficult. Presbyopia, as this condition is called, can be frustrating on land, but for us scuba divers, it can make access to critical information on our dive, specifically information on our dive computers, depth gauges, and pressure gauges, challenging or impossible to read without assistance.

Various products exist to solve the issue (hey there are many divers out there who keep a magnifying glass on their BC to see their gauges, but we think we have more elegant solutions). Primarily divers can install temporary plastic reading lenses available in various powers at their local dive shop or get a mask from us (or send us their dive mask) to install permanent glass reading lenses. Reading lenses differ from our bifocal dive masks, as they only contain correction at the bottom of the mask. Bifocals on the other hand contain correction for distance at the top of the mask, and correction for reading at the bottom. You can check out my article and videos on prescription bifocal dive masks here.

Order a dive mask with reading lenses

Custom reading lenses installed in dive masks


As we produce our dive mask reading lenses in glass, any product safe for us on a dive mask remains safe to use on our lenses including sea buff, defog, and other products marketed for dive masks. We custom create our dive mask reading lenses to fit the shape of your dive mask along the bottom and we can produce them in powers from 0 and up although most commonly divers request powers around +2.00 to +3.00. We can also make reading glass with cylinder correction for those with astigmatism and who want to have the correction in their reading lenses for an additional cost.

Some examples of diving masks with reading lenses

How long does it take to get a dive mask with reading lenses installed?

Our standard turnaround time is about two business weeks when you order a dive mask with lenses from us or 2 weeks from when we receive your dive mask. Rush options are available for a fee in as little as 3 business days from when you order plus shipping.

How much do dive masks with reading lenses cost?

Reading lenses (at time of posting in August, 2022) cost $169.00 plus the cost of the mask and shipping. The lenses cost the same whether you get a mask from us or send us your mask- but shipping your mask to us does add a touch of cost as well.

Can you put reading lenses in any dive mask?

We can install our reading glass in any quality dive mask that has tempered glass lenses (any mask you get a dive shop should meet this requirement). Normally there is a small “T” for tempered or the word tempered spelled out on one or both lenses. We routinely put reading lenses (or “cheaters” as some call them) in Scubapro, Aqaulung, Cressi, Atomic, and other dive mask brands. 

Special considerations

A dive mask produced with double reading lenses for different distances- one fora. middle distance, and one for a reading distance such as gauges.

We make our lenses custom to order, so we can handle special requests. Professional photographers or cinematographers often want more than half the lens covered with reading glass as they spend the majority of their time viewing the underwater world through their camera viewfinder or monitor.

We can also place reading lenses at the top and bottom of a dive mask, as we did for renown underwater explorer and photographer, Jill Heinerth, so she can view her gauges through the bottom and camera monitor through the top of the masks.

For special requests, please contact us for pricing and time frame.

If you are having a hard time seeing your gauges or dive computer, we can help ensure the information is clear, feel free to shoot us a message or contact us with any questions.

You can also check out this article I wrote a few years ago about custom lenses for an atomic venom frameless dive mask we made for our friend Jim.

Our new lab is open! (Important address change)

A prescription dive mask with custom lenses sits on a table in front of a photo of a sea turtle.

See the sea rx opens larger lab in Houston

When I first started See the Sea RX, i was a diver frustrated with the prescription dive mask options available on the market. 

I remember being so scared after installing all our equipment that we would never receive an order. I never expected the tremendous response we have received and the thousands and thousands of divers, swimmers, and snorkelers who have trusted us with seeing clear in the water. 

I am excited to announce our next chapter: we have fully completed our transition to our larger lab with almost double the work space of our home for the last few years. 

Please take note of our new address, which is the best place to visit us, send us your dive mask for prescription lenses (such as bifocals), or shoot us some of your underwater photos to hang up:

See the Sea RX
8700 Long Point Road
Suite 203
Houston, Texas 77055

We have worked to update the address everywhere we can find, but if you find a spot it needs to be updated, please let us know!

How much is a prescription dive mask?

How much does a prescription dive mask cost?

One of the most frequent questions we receive is how much does a prescription dive mask cost. Prescription dive masks can run between $100 to slightly over $500. Factors such as lens type, turnaround time needed, the specific mask selected, and prescription strength can all effect the cost of your mask. As someone who wears prescription glasses (and dive masks) myself, I understand the considerations that go into the cost, and weighing the benefit. I can tell you that nothing beats descending to a gorgeous dive site and seeing everything sharper than I can even on land at times. In this article, I will discuss the different underwater vision products, what they can correct, and what they cost.

Stock lens dive masks $100-200ish

Stock lens masks use PREMADE lenses that work for a range of distance only corrections in the range of -8.00 to +4.00 SPHERICAL only correction. What this means is these masks are available for a relatively low price (in several mask options) in a range of prescriptions; however, these masks do NOT correct for astigmatism or prism, and they are not made in bifocals. If you have a simple (spherical only correction or a correction with very mild astigmatism within the range listed above), the stock lens masks are a great option. For those divers and snorkelers like me that have astigmatism, these masks do not work well. These lenses are available only for the masks we list on the stock lens page such as the scubapro d mask and the m200.

Prescription Swim Goggles: Starting at $245

Prescription swim goggles are a great option for those that do surface swimming. We can correct a wide variety of vision needs including prism for strabismus, bifocals, and very strong corrections (we have done up to a -28!). Extras such as bifocals, tints, and polarized lenses can increase the costs. 
I have some articles on our prescription swim goggles which provide information as well:

Prescription swim goggles with transition lenses.

For more on prescription swim goggles, click here

Prescription Full Face Snorkel Masks: Starting at $185

Some snorkelers really like being able to breath not just through their mouth but through their noses as well, which the prescription full face snorkel masks allow.

Our prescription full face snorkel masks can correct for a wide variety of corrections including options for prism, bifocals, and astigmatism correction. Adding bifocals or choosing the Aria QR+ version will increase costs slightly.

These masks cannot be used for diving (Although we do make prescription lenses for full face diving masks as well). ‘

The insert system allows prescriptions to be easily updated if your prescription changes   

Click here to purchase a full face snorkel mask

Custom Prescription Dive Masks: Starting at $165

Custom lenses for prescription dive masks are our hallmark product. Our lenses are available in options such as reading lens only at the bottom of the mask, single vision lenses (distance correction only), bifocals for distance and near correction, and the custom prescription lenses can correct for astigmatism (the cylinder correction on your prescription) and double vision or strabismus (corrected with prism).

The costs can vary for the custom prescription lenses and whether you are using your mask or getting a mask from us. We can use any quality dive mask with flat glass lenses. If you are getting a mask from us, our dive masks start at $60.00. Our custom lenses take approximately two business weeks to produce here in our Houston lab, but rush options are available for a fee. Custom bifocals in a high end mask can cost $400.00.

Rebreather Diving (With my Prescription Dive Mask) on the Fu Sheng Wreck in Sint Maarten

Rebreather diving in Sint Maarten

One of the ways we are differentiated is the fact that we are divers, not just opticians and optical techs. While the last two years have been challenging for us and others in the dive industry, I was finally able to start getting back in the water this year. The video above highlights a recent awesome dive we we are able to do on a wreck in Sint Maarten. For those wondering, I dive a prescription scubapro d mask with single vision lenses. 

I like to write about some of my dive travels with my own prescription dive mask and share them with you all.

In this article, I will also cover specific prescription dive mask concerns for rebreather divers.  (Be sure to check out my video above highlight the whole dive).

Dive mask and scuba equipment.

What is a rebreather?

A diver underwater with a rebreather diving along a wreck

In Scuba, we have a compressed air tank attached to a diving regulator (a first and second stage). Every time we inhale the regulator provides us (normally) air (or nitrox, or even other gases, depending on the dive) at the surrounding pressure, so our lungs can inflate. Every-time you exhale, all the air in your lungs exits the regulator as bubbles. The human body, however, is not so efficient as to extract all the available oxygen in a single breath of the same gas, so the bubbles contain a significant amount of wasted oxygen. If there was a way to recycle this air, you could extend your time diving.

On a simple level, this is what a rebreather accomplishes. Instead of all your exhaled air exiting as bubbles, you exhale into a counter-lung. The exhaled air then moves across a scrubber removing the carbon dioxide. As the oxygen in the breathing loop decreases, you either manually add, or the rebreather adds pure oxygen to the loop to keep your breathing gas at an ideal mixture. 

Prescription dive mask concerns for rebreather divers

If you are a rebreather diver, and like me need corrective lenses, there are a few unique concerns that open circuit divers don’t face. 

While heads up displays and computers for recreational divers have recently seen a surge in popularity (like the Scubapro Galileo HUD), they are a mainstay in rebreather diving. Rebreathers either utilize a heads up display (HUD) with a series of different color lights to indicate different rebreather conditions or a computer with a full digital display that can provide more information than the more basic HUDs. The most popular HUD computer is the Shearwater NERD, which I personally use on my Prism 2 now. 

The shearwater NERD uses a special lens to focus the display when the diver is looking at a distance, despite the computer sitting inches away from the diver’s face. This allows the diver to be watching his or her surroundings while also having the dive computer screen in focus. If the diver utilizes bifocals or readers in their dive mask, however, the near vision portion of the lens is not suitable for viewing the NERD (While beneficial to a standard light HUD). For rebreather divers who utilize bifocals or reading glass for near vision, we generally suggest using only distance lenses on the side of the mask they view the NERD (normally the right eye).  For more information on our bifocal lens scuba mask options, please read my article here. 

We are also able to produce fully customized lenses that include a reading section at the top of the lens instead of the bottom of the lens, where the NERD is placed, so the diver can use the top of the lens for photography or other macro work. 

Whether you dive a rebreather or open circuit scuba, our diving experience allows us to help you pick the right prescription lens for your needs. Feel free to give us a all or shoot us a message. Our prescription lenses are installed in house in our lab in Houston and are able to provide corrections for astigmatism, double vision, and other unique needs.

During my time on St. Martin, I dive the Fu Sheng wreck, a dive I have been trying to do since arriving on the island. The wreck, nestled in about 110 feet off the coast of St. Matin, remains largely in tact. The wreck sank unintentionally, and is one of the older wrecks on the island.

The wreck hosts a variety of marine life including garden eels, moray eels, rays, and a mix of coral.

Diving the wreck on my rebreather allowed me a dive time of just over an hour with only a short deco time of 20 minutes on the way to the surface.

For diving in St. Martin, I have used both of these operations, which have supported rebreather diving (and recreational open circuit). I do not receive anything in exchange for recommending them, and I found them to both be great dive centers.

How to Care for your Prescription Scuba Diving Mask

How to care for your prescription dive mask:

Ordering a prescription dive mask is a great investment in your diving or snorkeling life, and it can range from a luxury for those with weaker vision correction to an absolute necessity for divers, swimmers, or snorkelers with strong prescriptions. Once you receive your mask, proper care can ensure years of use. I often get asked by divers, how do you take care of your new prescription dive mask?

In this article, I will go over our suggestions for care and maintenance of your new prescription dive mask. These instructions will pertain to our custom prescription dive mask products and NOT to prescription swim goggle or full face snorkel masks. Prescription full face snorkel masks and swim goggles have lenses that are generally polycarbonate (same for the full face diving masks from OTS and Oceanreef which we make lenses for as well) while prescription dive masks use glass lenses. This makes a huge difference as glass lenses can tolerate defog and even products like sea buff which has some grit. Those products would damage polycarbonate or plastic lenses.

For those that want the quick answers without reading my full article, here are the general do’s and don’ts with your prescription dive mask:

  • Do use defog before diving
  • Do clean your mask lenses with sea buff or a small amount of dish soap if desired
  • Do be careful when transporting your mask in checked bags (I recommend taking your mask in your carryon bag). Add some padding to the mask case if possible.
  • Do rinse your mask off after diving
  • Do NOT take an open flame or heat to your dive mask lenses to “burn off” any film.
  • Do NOT leave your mask out in the sun

How to care for your prescription dive mask when you first get it:

As all of us scuba divers are told when we are first trained to scrub a new mask when we receive it, to remove any film from the production process that will prevent mask defog from working. While this is correct for any off the shelf mask, our lenses are custom made, and we complete both a scrub and burn off process of the prescription and mask lenses before the installation and shipment; however, you are welcome to scrub your lenses further with toothpaste or seabuff without hurting the lenses.

 

Some masks like the scubapro dmask have a UV / reflective coating on the outside of the lenses which can be damaged with scrubbing. Be sure to refer to the manufacturer’s guidelines for your specific mask.

Can I use a lighter to burn my prescription dive mask lenses?

DO NOT USE HEAT OR A FLAME TO TREAT YOUR LENSES. We burn the lenses prior to installation, but heat after the installation is likely to damage the laminate in the glass and will not be covered by our warranty.

How should I treat my prescription dive mask before a dive?

You can treat your prescription dive mask like any normal mask before a dive. Use your favorite defog before the dive (I like sea drops, and I have no fogging in my scubapro d-mask with lenses).

One of the biggest ways divers break their prescription (and nonprescription dive masks) is dropping them onto hard boat decks, docks, rocks (we have even seen some stepped on).

After your dive, like with any other dive equipment, be sure to rinse off any saltwater or chlorine with fresh water before packing your dive gear for the day. Do not leave your mask out in the sun as that can cause color bleaching.

Whether you have bifocals, reading lenses, single vision, or other corrective lenses in your scuba mask from See the Sea, proper care of the mask will lead to years of clear diving.

One last note- When traveling, I encourage divers to carry their mask on instead of using a checked bag as a lost or damaged checked bag containing your prescription dive mask is a sure way to miss out on some clear dives.

Prescription Dive Masks for Strong Prescriptions

Scuba diving mask with light pink frame and higher strength prescription lenses.

You have a super strong prescription and scuba dive- what do you do?

One of the biggest rewards for us is when we can help someone with a strong prescription dive when other opticals told them they can’t make a dive mask for their needs. We have produced masks with lenses as strong as -28!

I get phone calls every day from divers who ask if we can use their prescription as it is strong. Most of the time, their prescriptions are what we consider relatively moderate (+4 through -4), and those prescriptions are no issue in really any of our dive masks.

Strong prescriptions than that are not an issue for us (and we routinely make masks with high cylinder powers or prism), but higher power prescription dive masks tend to work better in some masks than other masks.

What is a strong prescription?

When creating lenses for prescription scuba diving masks, we require any prescription with a single vision spherical equivalent of -6 and stronger, or +4 and stronger to use our high index glass lenses. This enables us to produce a thinner lens in this prescription ranges. This is also the line where we start considering what masks can support these stronger lenses without risking the lens touching the diver’s face or other complications.

Best scuba diving masks for stronger prescriptions

Divers and snorkelers do not have to buy a mask from us to install corrective lenses, but in general there are several factors that should be considered when choosing a mask to accommodate stronger prescriptions in dive masks. 

  • Smaller lens size. This enables us to produce a prescription lens as close to edge to edge as possible without increasing thickness dramatically.
  • Deeper skirt. A deeper skirt keeps the dive mask a bit further from the diver’s face preventing issues with lens thickness. 
 
 

Below are the masks we recommend most often for those with stronger prescriptions which we keep in stock.

Scubapro d-mask ($185 + lenses)

The scuba pro d-mask which can be reviewed in depth in my article here, comes in three sizes to accommodate a wide range of faces. The lenses contain a slight hue to provide color correction at depth and a UV coating to protect your eyes at the surface.

IST m200 Aluminum Frame Mask ($94 + Lenses)

The M200, which is an average fit masks fits those with slightly narrower faces as well as up to a medium/ regular fit. It only comes in one size and the aluminum frame does provide robust support for the mask. We carry the M200 in clear and black skirts as well as several frame colors.

IST m100 Aluminum frame

The M100 is the bigger brother to the M200 dive mask and is a bit larger. Like the m200 we carry it in a black or clear skirt as well as several color options for the frame. We also carry the M100 with color correcting / mirror lenses which can also support stronger prescriptions.

What scuba masks should I avoid with a stronger prescription?

Atomic Subframe with stronger prescription lenses

There are no hard and fast rules as each mask and each prescription are different, but in general, as the prescription strength increases, we discourage divers from using the synergy II or frameless masks which are very popular for divers with milder prescriptions. The Atomic Subframe also can have lens thickness concerns with increased prescription strength. These are all very popular masks on our website and for divers in general, and they should absolutely be considered for prescriptions within the more moderate range. 

other considerations for snorkelers, swimmers, and divers with strong prescriptions!

If you do not have much astigmatism (you can give us a call to discuss whether this applies to you or not), some of our masks support less expensive stock lenses (available here). Stock lens masks generally support sphere correction from -8 up to +4 without correcting for any astigmatism, prism, or those that need a multifocal lens. 

If you are just swimming or snorkeling, our prescription swim goggles and full face snorkel masks can support your exact prescription, including high powers, for a lower price than our glass dive masks.

 

Prescription Swim Goggles

Our prescription swim goggles start at around $200 including prescription. We recently shipped out a swim goggle with +15 lenses!

Prescription Full Face Snorkel Masks

Our prescription full face masks are also a more affordable option for those with strong prescriptions who only want to be able to snorkel.

If you have any questions regarding unique prescriptions or want help picking out a prescription dive mask, don’t hesitiate to reach out!
