Prescription dive masks & snorkel masks

See the reef the way it was meant to be seen. Our prescription dive masks and prescription snorkeling masks (RX masks) put your exact diopter into a comfortable, well-sealing frame.

So you can skip contacts, skip renting a gross mask that won’t have your prescription, and avoid missing that turtle or puffer fish cruising by. Contacts can dry out in saltwater and trap sand; an RX mask gives you crisp vision the moment you hit the water.

  • Nearsighted/Shortsighted (Myopia)

    If things in the distance look blurry, like coral reefs, fish, or boats, you’re likely nearsighted. Our minus (-) prescription lenses bring far-away details into focus, so you can see the underwater world clearly while still keeping close-up vision sharp.

  • Farsighted (Hyperopia / Presbyopia)

    If you see clearly far away but struggle to focus on things up close, like your gauges, camera, or the fish right in front of you, you’re likely farsighted.

    Our plus (+) prescription lenses help bring everything into focus at once, making it easier to see clearly both near and far underwater.

  • How Prescription Lenses Work Underwater

    Whether your lenses are plus or minus, they simply adjust how light enters your eyes so everything, from nearby coral to the open blue, looks crisp and clear.

Choosing your perfect Rx Snorkel/Scuba Mask

To make things easy, we’ve split it into two quick steps: use our Lens Calculator to choose your prescription strength, then take the Find-My-Mask quiz to match fit and face shape. Together they remove the guesswork and help you order the right prescription dive mask or prescription snorkel mask in minutes.

About rounding down your Prescription

Underwater, the water layer and lens distance mean you don’t need the full spectacle power. Round your sphere power down toward 0 by about 0.50–0.75 diopters for most prescriptions. This applies to both nearsighted and farsighted RX dive masks and typically delivers sharp, comfortable vision for scuba diving and snorkeling without over-correction.

If you have a ruler handy, use our Mask Sizing Helper page. It includes a simple how-to guide for measuring face width and nose-to-brow height.
