Custom prescription lenses for diving masks – precise fit and key technical aspects
Lenses in a diving mask – how do we choose the right solutions?
The final size and shape of corrective lenses for a diving mask depend on the technological possibilities of their production. Each diving mask has a specific structure, and the adjustment of optical lenses requires taking into account both the user's prescription and the specifics of the given mask. Our goal is to provide the largest possible corrective surface to increase the field of vision and improve diving comfort.
It is worth remembering, however, that in some cases, full coverage of the entire lens surface in the mask may not be possible. This is determined by both the shape of the mask and the specifics of the given vision correction. Thanks to our knowledge and experience, we try to optimize the arrangement of the lenses in such a way as to provide the best possible vision underwater.
Why is lens quality crucial?
Good underwater vision is extremely important for both the comfort and safety of the diver. Individually fitted optical lenses for the diving mask allow for precise adjustment of the correction, eliminating the problem of fogging or blurred vision. We offer lenses made of high-quality materials, resistant to damage and adapted to the conditions prevailing underwater.
Thanks to modern optical solutions, even with technological limitations related to the mask design, we can guarantee sharp and clear vision. We use modern lens assembly technologies to best match them to the shape of the mask and the individual needs of the user.
Safety and comfort - our priorities
Our main goal is to provide users of corrective diving masks with the highest level of safety and excellent quality of underwater vision. A diving mask is not just a piece of equipment, but a key functional product that is supposed to enable precise observation of the underwater environment.
We always try to find the best possible solution, however, if there are technical limitations that prevent us from fulfilling the order as required, we reserve the right to cancel it. We operate transparently, always informing customers about the possibilities and limitations related to the installation of corrective lenses for diving masks.
Thanks to our knowledge, experience and the use of modern technologies, we can guarantee that each diving mask with corrective lenses will be maximally functional and tailored to the individual needs of the user.

How to improve underwater vision?
Diving is an extraordinary passion that allows you to discover the underwater world in all its glory. However, for people with visual impairments, it can be a challenge - traditional masks do not provide adequate visual acuity. We present solutions that allow you to enjoy a clear image underwater.
Whether you are a professional diver or just starting your diving adventure, the right prescription lenses will ensure full visual acuity, safety and comfort of exploring underwater depths. Depending on your needs, you can choose single-focal, progressive or bifocal lenses. Check which solution best suits your vision defect.
Single vision lenses – sharp vision at any distance
Single-focus lenses are basic optical lenses that have a uniform corrective power across the entire surface. They are designed to correct a single visual defect – myopia, hyperopia, astigmatism or presbyopia. They are most often used for vision at one specific distance.
Choose single vision lenses if:
✔ You use one pair of glasses every day to see at a constant distance.
✔ You don't need different lens values for near and far vision.
Single vision lenses for sharp close-up vision
Single vision lenses are basic optical lenses that have a uniform corrective power across the entire surface. They are designed to correct a single visual defect – myopia, hyperopia, astigmatism or presbyopia. Ideal for people who need vision correction for reading and close-up work.
Choose these lenses if:
✔ You use glasses for reading or working at a computer.
✔ You have difficulty seeing close objects clearly.
Single vision lenses for sharp, distant vision
Single vision lenses are basic optical lenses that have a uniform corrective power across the entire surface. They are designed to correct a single visual defect – myopia, hyperopia, astigmatism or presbyopia. An excellent solution for people who need vision correction to see clearly at a distance.
Choose these lenses if:
✔ You have no problem seeing up close without glasses, but you need correction for long-distance vision.
✔ You wear glasses for driving, watching TV, or other activities that require sharp vision only at a distance.
Progressive lenses – smooth vision at any distance
Progressive lenses are an advanced solution for people with presbyopia. Thanks to the smooth transition between different optical zones, they provide clear vision both up close, at medium distances and at long distances - without having to change glasses.
Choose these lenses if:
✔ You wear progressive glasses every day.
✔ You want to see comfortably at any distance without having to change your mask or head position.
Franklin bifocal lenses - two vision zones
Bifocal lenses are a classic solution for presbyopes who need two different optical powers – one for distance vision and one for reading. A characteristic dividing line separates the two vision zones.
Choose these lenses if:
✔ You wear bifocals or wear two different pairs of glasses.
✔ You need clear vision both near and far, but don't want progressive lenses.
Choosing the right lenses for your diving mask is a guarantee of comfort and safety underwater. Choose the solution that best suits your needs and enjoy crystal clear vision during every diving adventure!

Which lenses for a diving mask?
Choosing the right lenses for your diving mask is a key element in ensuring clear and comfortable underwater vision. Depending on your individual needs and visual impairment, you can choose lenses with different refractive indexes. The material they are made of affects their thickness, weight, durability and optical quality.
Index 1.5 mineral lenses – standard quality at an affordable price

✔ Affordable price and wide availability.
For whom?
➡ Recommended for people with visual impairments ranging from -4.00 to +4.00 diopters.
➡ Users looking for durable and economical lenses.
1.6 Index Mineral Lenses – Thinner and Lighter for More Comfort
Glass lenses with an index of 1.6 are a more technologically advanced solution. Thanks to their higher refractive index, they are thinner and lighter, which affects their greater aesthetics and comfort of use.
Advantages:
✔ Up to 25% thinner than 1.5 index lenses, improving the appearance of your glasses.
✔ Lighter and more comfortable to wear.
For whom?
➡ Recommended for people with visual impairments in the range of over -4.00 and +4.00 diopters.
➡ Users who value thinner and more aesthetic lenses.
1.7 index mineral lenses – an ultra-thin and elegant solution
Lenses with an index of 1.7 are advanced optical glasses designed for people with high visual impairments. They are significantly thinner and lighter, which makes the glasses look more elegant and more comfortable to wear.
Advantages:
✔ Up to 40% thinner than standard 1.5 lenses.
✔ Very aesthetic appearance – perfect for thin frames.
For whom?
➡ People with visual impairment above -6.00 diopters.

How to choose the perfect mineral lenses?
➡ If you have a slight visual impairment (-4.00 to +4.00 diopters) → choose index 1.5
➡ If you want thinner and lighter lenses → choose index 1.6
➡ If you have a high visual impairment and want ultra-thin lenses → choose index 1.7
Choosing the right lenses is key to comfort and sharp vision. Choose a solution tailored to your needs and enjoy maximum comfort while diving!
How to choose a diving mask?
Choosing the right diving mask is essential to ensure comfort, safety, and enjoyment of your diving experience. Here are some steps to consider when choosing a mask:
1. Adjusting the diving mask
The diving mask must fit perfectly to the face to ensure a seal. To check this:
- Place the mask on your face without putting on the strap.
- Inhale air through your nose – the mask should seal.
- Check that the mask stays on your face, even when you tilt your head forward.
2. Shape and seal of the diving mask
Different diving masks come in different shapes, so it's important to find one that fits your face:
- Put on the mask and tilt your head back, looking up.
- Run your finger around the edge of the mask to make sure it touches your face all the way.
- Make sure all hair is away from your face to avoid leaks.

3. Size of diving mask
Diving masks are available in different sizes:
- Place the mask on your face without using the strap.
- Inhale through your nose and remove your finger – if the mask stays in place, the size is correct.

4. Viewing angle and volume of the diving mask
A well-chosen diving mask should provide a wide viewing angle and have a small internal volume:
- Check the horizontal and vertical viewing angle.
- A mask with a smaller volume makes it easier to clear the mask when freediving.

5. Diving mask collar color
The diving mask collar can be made of black or transparent silicone:
- Transparent silicone widens the viewing angle and is brighter, which is important for people with claustrophobia.
- Black silicone may cause feelings of claustrophobia in some people.

7. Diving Mask Care
To ensure your diving mask lasts for many years, you need to take proper care of it:
- Rinse your mask with fresh water after each dive.
- Store the mask in a cool, dry place, away from sunlight and heat sources.
When choosing a diving mask, keep these steps in mind to find a model that will keep you comfortable and safe while diving.
