Diving Mask with Prescription: Options, Costs & the Affordable Solution
Diving mask with prescription – the essentials at a glance:
The options: ground lenses from an optician, ready-made corrective lenses for two-lens diving masks, contact lenses or clip-in lenses that you place in the mask yourself.
The most affordable solution: Our prescription lenses from −8.0 to +8.0 diopters. They hold with a suction cup and cost €16.99 per lens – a fraction of an optician solution.
Important: They only fit a diving mask if it has one continuous lens (single-lens mask). Masks with two separate lenses have the frame in the middle – exactly where the suction cup needs to hold.
In this guide you'll learn what options there are, what they cost and how you can convert your mask yourself in a few seconds with our prescription lenses.
1. Why glasses and contact lenses are no solution
Normal glasses under the mask don't work: the temples would keep the seal permanently open, letting water run into the mask. Contact lenses in the sea are uncomfortable, because every now and then you have to rub the salt water out of your eyes.
2. Diving mask with prescription: the options at a glance
| Solution | How it works | Who it's for |
|---|---|---|
| Lenses from an optician | Corrective lenses are ground to fit and glued or fitted into the mask | Complex values, varifocals, astigmatism |
| Ready-made interchangeable lenses | Two-lens diving mask whose lenses are swapped for corrective lenses | Divers with simple minus values |
| Contact lenses | Normal contact lenses under a normal mask | Uncomfortable, because the salt water keeps making you rub your eyes |

Insertable prescription lenses The best solution |
Two lenses to your values, held on the inside of the visor by a suction cup – €16.99 per lens | Snorkelers and holidaymakers with plus or minus values View prescription lenses → |
For most snorkelers, the last option is the most practical. You don't need an optician appointment, you choose the strength for each eye separately, and on holiday the lenses are in place in seconds.
3. How much does a diving mask with prescription cost?
The price differences are big. Ground lenses from an optician quickly cost several hundred euros, depending on strength and mask. Ready-made interchangeable lenses for two-lens masks usually cost a mid two-digit amount per lens, plus the matching mask.
Our prescription lenses cost €16.99 per lens. So for both eyes you pay €33.98 and save up to €170 compared with an optician solution.

4. How our prescription lenses work
The lenses consist of two individual lenses, one for the left eye and one for the right. You choose the right strength for each eye, clip both lenses together in the middle and attach them with the suction cup to the inside of the mask lens. The suction cup sits in the middle between the lenses, roughly at the level of the bridge of your nose.
- Choose the strength for left and right and order both lenses
- Clip the two lenses together in the middle
- Make sure the inside of the mask lens is clean and dry
- Position the lens centrally in front of your eyes and press on the suction cup – done
No glue, no tools, no optician. And if someone else uses the mask, you simply take the lens out again.
5. Single lens or two lenses: which diving mask fits?
This is the most important question if you want to use the lenses in a classic diving mask. Because the suction cup sits in the middle, it needs a smooth, continuous glass surface there.
- One continuous lens across both eyes
- Suction cup holds in the middle of the glass
- Full-face snorkel masks also have a continuous visor
- Two separate lenses
- The frame bridge sits in the middle
- The suction cup can't hold there
6. Best in a snorkel mask
We developed the lenses for our own full-face snorkel masks. That's where they fit best: the visor is large and continuous, the distance to the eyes is right, and the lens sits exactly where you look.
The lenses fit the Seaview Pro, the Seaview Pro Plus, the Seaview X, the Seaview Y and the Seaview Kids. For glasses wearers in particular, the full-face mask has another advantage: you breathe through your mouth and nose, and the anti-fog system keeps the view through the lens clear.
Our recommendation for glasses wearers: Seaview Pro with prescription lenses
180° panoramic view, natural breathing through mouth and nose, separate airways with check valves and room for the prescription lens right in front of your eyes. If you also want to dive down, choose the Seaview Pro Plus with pressure equalization.
7. Choosing the right strength
- Take the values from your glasses prescription: What matters is the value under “Sph” (sphere) for each eye.
- Your exact strength isn't available? Then choose the next lower step. Under water, that is perfectly enough for clear vision in practice.
- Short-sighted (minus values): Better choose slightly weaker than too strong, otherwise seeing becomes tiring.
- Astigmatism or varifocals: The lenses have pure plus or minus values. With strong cylinder values or varifocals, a custom solution from an optician is the better choice.

8. Conclusion
A diving mask with prescription doesn't have to be expensive. For most glasses wearers, insertable prescription lenses are the simplest solution: choose your strength, attach with the suction cup, go snorkeling. In a classic diving mask this works if it has one continuous lens. The lenses fit best in a full-face snorkel mask like the Seaview Pro, for which they were developed.
Everything for clear vision under water:
Prescription lenses – −8.0 to +8.0 dpt, €16.99 per lens
Seaview Pro – our all-rounder with 180° panoramic view
Seaview Pro Plus – with pressure equalization for diving down
