Scubapro D Mask with Franklin Bifocals

Scuba pro D-Mask & Franklin Bifocals

It is no secret that the scubapro d mask has recently become one of my favorite dive masks for prescription dive mask lenses. I recently wrote a post just detailing the d mask. Below are my reasons for loving the d-mask:

  • 3 sizes available to fit the vast majority of people. If you order a size and it doesn’t fit, we can move the lenses quickly to a different size as they all share the same lens size.
  • UV coating to protect your eyes at the surface of the water.
  • Slight color correcting tint to bring some red coloring back at depth.
  • Supports a wide range of prescriptions INCLUDING very strong prescriptions.
 
This article is not meant to be another review of d mask, however, but it is an overview franklin bifocal lenses in the scubapro d mask and who may want them.

For some divers, the reading /near vision lens portion in the standard bifocal just is not enough area for the tasks they are performing underwater.

What are bifocals for in a dive mask?

In a recent post, I reviewed bifocal dive mask options and I went over the different types of bifocals available in scuba diving masks. 

The term bifocal can be confusing and divers often confuse it with our reading lenses. Bifocal lenses correct for both distance correction and near vision correction. Our dive mask reading lenses only provide correction for near vision and we normally install them in the bottom third of the dive mask (here are some reading lenses we installed in to an atomic venom frameless mask). Our bifocal lenses can also include correction for prism and astigmatism.

For dive mask we offer three main bifocal options:

  • Standard (ST-28) bifocals
  • ST-35 Bifocals
  • Frankling Bifocals
 
 

The ST-28 and 35 refer to the lens being a straight top bifocal (lens design) and the width of the bifocal segment in each eye. It is really important to keep in mind, the width of the bifocal segment is before the lens is cut for the dive mask. Different pupillary distances and dive mask design mean all bifocal segments will be a bit narrower than in the uncut lens. 

The end result with the st28 or st35 dive mask bifocal is a lens that contains a half moon segment for near correction at the bottom of the mask. The difference between these options and the franklin bifocal is the franklin bifocal includes separate lens that spans the bottom of the mask for a large amount of near vision correction.

The franklin bifocal advantage when scuba diving

In the above two images, you can see the two major different styles of bifocals. In the left image, we installed a st35 bifocal lens. You will likely need to click on the image to view it larger in order to see the bifocal line, but you will see a near vision segment that extends across about the bottom two thirds of the mask (in width). In the franklin bifocal on the right, you can see the near vision segment of the lens is a completely separate lens from the distance vision lens, and the reading/near vision area of the lens extends all the way to the bottom of the mask and all the way across the mask. 

For divers who engage in activities such as professional photography or cinematography, it is important to have a much larger near vision correction area. The franklin lens is also completely customizable. Some divers want the split to result. in a larger near vision area. We have made franklin dive mask bifocals that are 70% near vision and only 30% far vision. Depending on the diver’s needs, we can customize the lens sizes. If you only need bifocals to see your gauges or dive computer, the standard bifocals are a more economical option. 

Another benefit of the franklin bifocal is the ability to use high index lenses for those with strong prescriptions resulting in a thinner lighter lens than if we had done a traditional bifocal in crown glass. 

How much are bifocal lenses and how to order

Our standard bifocal lenses are available for order on the order page (seethesearx.com/ordering). Standard bifocals start at $295.00 + dive mask. The scubapro d mask costs $185.00.

The franklin bifocal is a fully custom option and is not available for order online. To set up an order for a diving mask or goggles with franklin lenses, please give us a call at 18003567190.

What’s new (with prescription dive masks) in 2021?

A diver under blue water in Cozumel, Mexico is wearing a scuba pro d mask as well as a Hollis Rebreather.

Whats new at See the Sea?

2020 was supposed to be the year (at least of puns) for vision correction. Like a lot of folks, 2020 was full of challenges for me as well as the diving community at large. I was super excited to receive my new Ikelite housing for my Canon 5D MK IV in February last year with plans of all the diving I would do throughout 2020… well we know how that went. I am still getting some use out of my housing, and we are Ikelite dealers if you ever have any questions about getting a camera/underwater camera set up. I have a few trips planned for this year, and I am super excited to post pics and vids from those trips. 

I unfortunately had a bad bout of COVID in the middle of 2020 which included hospitalization. There remain a lot of questions regarding diving post COVID. I am very lucky to be friends with Dr. Robert Sanders, the medical director, and hyperbaric & diving medical specialist, for NASA’s Neutral Buoyancy Lab. Hopefully we can post an interview with Dr. Sanders about recommendations regarding COVID & diving soon.

On the positive side, See the Sea RX continues to grow, and we have continued to help divers around the world see clearly with underwater lenses. I authored an article about prescription dive masks for Diver’s Alert Network which was published in Alert Magazine in May, 2020. You can read the article by clicking on the Alert Diver Cover to the right.

We have also made a few changes to the site, and added a few mask options that I will review below. 

Scuba pro d mask

We recently added the new Scuba Pro D-Mask as an option for our various prescription lenses last month.

If you want more information on the D Mask, check out my full article on them here.

The D-Mask is available in three different fits, and comes standard with UV coated & tinted lenses. We can install any of our custom prescription lenses including single vision, high index, bifocals, or readers.

Full face snorkel masks

As an authorized Oceanreef dealer, we sell the highest quality full face snorkeling masks with and without prescription lenses. We added them to our site in late 2019, but since then we have made a few changes. I covered prescription full face snorkeling masks in a blog post here.

You can now order full face snorkeling masks without prescription lenses on our order page: https://seethesearx.com/order-full-face-mask/

 

Custom reading lenses

While most folks will never need a mask like the one on the right (a custom Atomic Venom with dual reading lenses made for rebreather diver and photographer Jill Heinerth), most of us will need some help with seeing our gauges or dive computer as we get older. 

If your gauges are looking a little fuzzy these days, reading lenses can help. If you have any special reading lens needs or want something fully custom like Jill, give us a shout, and we will draw up a draft for your review. 

The benefit of the dual reading lens mask you see here is it allows Jill to see her gauges & rebreather HUD from the bottom of the mask while also using the top of the mask for her camera controls & monitor. 

Other updates & Changes

We have made various other changes to See the Sea RX including adding atomic aquatics diving masks, adding more prescription swim goggle options as well, and working on innovative lenses to help you see better while diving.

As always, if you have any questions about prescription dive mask lenses or any of our products, don’t hesitate to reach out.

Scuba Pro D-Mask with Prescription Lenses

Scuba Pro D-Mask Origins

When I first starting teaching Scuba at Dive World Scuba while in College, the Scuba Pro D400 mask was still in production. The darth vader like contraption offered a different design than common second stages. 

ScubaPro brought the D series regulators back recently, and with it a new mask, the D-Mask in 2020. Soon, online ordering will be available for the D-Mask on our site (you can still call us and order it over the phone as well as send us your own D-Mask to have lenses installed), but in the meantime, I wanted to provide you with a brief overview of the D-Mask, who would want it as a prescription dive mask, and some photos of a d-mask with prescription lenses we installed.

Overview of the d mask

When designing the D-Mask, ScubaPro included a few unique features:

  • UV coated lenses. Most dive masks on the market do not include a UV coating to protect your eyes at the surface of the water; however the D-Mask does.  The lenses also have a slight purple hue to help provide accurate colors underwater despite the UV coating.
  • Various size options. The D-Mask comes in three skirt sizes (seen on the right)- Small for petite adults or children, medium for most average adults, and wide for those with wider faces.
  • Trufit skirt- similar to the skirt on the synergy series of masks from Scuba Pro. 

 

Even if the D-Series regulators do not interest you, the D-Mask style is unique and offers a prescription dive mask option in a moderate volume mask. The Scuba Pro Heads Up display dive computers (Galileo) easily attaches to the D-Mask, and the mask comes with a quality fabric dive mask case. 

Sizing options for Scuba Pro D-Mask. The S mall is really for very petite adults or children. The medium for most average adults. The Wide fits wider faces.

Prescription optical lens options for the d-mask

The D-Mask is available with all custom lenses from See the Sea RX. This includes:

  • Single Vision Lenses: these lenses correct for distance only (and available in high index for strong prescriptions).
  • Reading Lenses: These lenses do not correct for distance, but are normally located at the bottom of the mask to help divers see their gauges, camera, or computer. 
  • Bifocal Lenses: Bifocal lenses come in several options and help scuba divers correct for both near and distant vision problems. I wrote a long article covering the dive mask bifocal lens options, which you can read here. 
 
Another feature of the D-Mask is it does accept our stock lenses. Stock lenses are premade off the shelf lenses that can only correct for distance vision and do NOT correct for astigmatism (or prism). Stock lens dive masks are more affordable than our custom prescription dive masks for those whose prescriptions fit the parameters. The D-Mask with stock lenses can be ordered here. 

Whether you have optical needs that require custom lenses or a simple prescription which can be corrected with stock lenses, the Scuba Pro D-Mask with lenses from See the Sea RX is a great option for a lot of divers.

(The D-Mask on the left of this paragraph had custom bifocal lenses installed by See the Sea RX).

How to order a d-mask with prescription lenses

You can order the Scuba Pro D Mask with either custom or stock lenses from See the Sea. 

If you meet the following, stock lenses may work for you:

  • Distance only prescription (within -5.00 up to +4.00)
  • No prism or astigmatism correction needed
  • No near vision (bifocals) needed
 
If you fit within those parameters, the Scuba Pro D-Mask with Stock Lenses can be ordered here. 

 

If your prescription is out of range of stock lenses, if you require bifocals, or if you need astigmatism or prism correction, the Scuba Pro D-Mask with custom prescription lenses can be ordered here. 

If you already have a D-Mask and want us to install lenses, you can order the lenses at SeetheSearx.com/ordering and click on “I have a mask”.

The scubapro D-Mask is located on in the middle of our mask selections on the custom lens ordering page.
