About Scuba Prescriptive Lenses
Corrective and reading lenses for the Tusa Freedom Ceos, Mares X-Vision, Cressi Focus and Scubapro D-Mask, plus stick-on myopia and bifocal lenses. Each lens fits only the mask it is named for, so match the model exactly and check whether the listing is one lens or a pair. Frames are in prescription masks.
How to choose prescription lenses for a dive mask
Many divers are short-sighted or long-sighted, and a gauge or computer you cannot read is a safety problem. There are three routes: stick-on lenses, drop-in optical lenses and a mask built for corrective lenses. Stick-on lenses cost about R300 to R400 and optical lenses about R800 to R1,000.
The options
- Stick-on lenses. A thin film lens that sticks to the inside of the mask lens, sold in fixed strengths for myopia or bifocal reading. They are cheap and work on single-lens and twin-lens masks.
- Drop-in optical lenses. Replace the mask's own lens in a twin-lens mask, in fixed steps. Our range includes Scubapro, Tusa, Cressi and Mares models.
- Custom lenses. Strong prescriptions or marked astigmatism may need custom bonded lenses or contact lenses.
Choosing a strength
Take your own spectacle prescription, then check which strengths the maker offers for your mask. Reading-strength bifocal lenses help you read a computer at arm's length. A prescription mask comes with lenses fitted. Fit matters first, so buy the mask that seals, then the lens.
Questions we get asked
What strength lenses can I get for a dive mask?
Many makers sell drop-in lenses from about 0 to -8.00 and 0 to +4.00, in fixed steps. Stronger prescriptions need custom lenses or contacts.
Can I wear contact lenses to dive?
Many divers do, with soft lenses, and a mask that does not leak. Ask your eye doctor, and carry a spare.
Do stick-on lenses fall off?
They stay put when the lens is clean and dry before fitting, and can be removed and replaced.
