    We do not ask for a prescription upload for reading lenses as you should be using a generic reading strength. If after placing your order you have questions about the reading power or if you have a prescription you want us to review, feel free to email or call us, and we will be happy to discuss if you are using the right reading power

Material Type

  • I take my glasses off to read. Please leave the bottom of the dive mask without prescription glass, so I can see my gauges/ dive computer.

  • Bifocal Type *

    For divers who need distance and near correction to see their gauges, computers, or cameras underwater
    Generally for photographers or those that want a larger reading area, the FT35 has a 15% larger reading area than the standard bifocal. It is 35 mm wide BEFORE it gets cut for your mask
    For distance and near correction- for divers who want to maximize the near vision with a fully customized split made to order. We use two separate lenses per eye to enable the diver to have complete control on what percentage of the dive mask can be used for distance and near vision. This is the gold standard for professional photographers and cinematographers. In order notes please indicate what percent of lens you would like for near and distance or mark your mask before shipping to us.

  • Reader Type *

    Our standard reading lens covers about the bottom 25% of the dive mask completely across the mask. If you would like a custom set height, please add a note to the order.
    Gauge readers are small lenses placed near the nose pocket of the inside mask to help you read your gauges or dive computers.
    Oversized readers cover more than 1/3 of the mask and go as high as you would like. This is preferred by professional photographers and underwater cinematographers. We will contact you after the order is placed to discuss your specific needs.

  • The higher the prescription, the thicker the lens. For lens powers greater than ±4, we encourage customers to purchase our high index glass lens. This lens is significantly thinner at greater powers than traditional glass. For powers over ±6, we require the high index option to properly install the glass into your mask.
