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.

1. Selection of the Diving Mask and Preparation for Measurements

Select the diving mask model on which the measurements will be performed and which will be ordered. Measurements must be carried out on the same mask model that will be used for lens installation.

Preparation for Measurements:
- Put on the selected mask model.
- Mark the position of the pupil on the lens with a marker while looking straight ahead.
- If ordering lenses for near vision, additionally draw a horizontal line indicating the lower edge of the lens.
- Optionally, apply transparent tape to the lens to check if the lens edge interferes during diving, taking your personal preferences into account.
- If you are using a test mask, leave the markings on the lens — do not remove them.

Taking the Photo:
- Take a photo of your face wearing the mask, holding the camera at eye level.
- Look straight ahead and maintain a natural, upright posture.
- Ensure that the pupils and the markings are clearly visible in the photo.

Submitting the Photo:
- Upload the completed photo via the order form or send it to kontakt@maskinurkowe.pl, including your order number.

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!

Selecting the correct lens material for prescription swimming goggles is essential for visual comfort, proper goggle balance, and safe use under water. Unlike everyday eyeglasses, swimming goggle lenses operate in a confined space and in conditions of constant humidity and pressure changes. For this reason, the physical properties of the lens material are just as important as the prescription itself.

One of the key parameters of optical materials is the refractive index, commonly referred to as the index (e.g. 1.5, 1.6, 1.67). A higher index allows thinner and lighter lenses to be produced for the same optical power, which directly affects comfort and stability when worn in swimming goggles.

Index 1.5 lenses are made from a classic optical material with stable performance and good visual quality. They are best suited for low to moderate prescriptions. In swimming goggles, the slightly greater thickness of index 1.5 lenses usually does not pose functional issues, especially for recreational use. This option is often chosen as a reliable and cost-effective solution.

Index 1.6 lenses offer a noticeably better balance between thickness and weight. Reduced lens mass improves goggle stability on the face, reduces pressure on the sealing area, and increases comfort during longer swimming sessions. This material is commonly recommended for medium to higher prescriptions and for users who swim regularly.

Index 1.67 lenses are high-refractive materials designed for higher vision corrections. They allow the production of very thin and lightweight lenses, which is particularly important in swimming goggles due to limited mounting space. This index is recommended for users with stronger prescriptions who require maximum comfort, minimal lens thickness, and precise optical performance.

An alternative material category is Trivex (index 1.53). Trivex lenses are characterized by very high impact resistance combined with low weight. The material offers good optical quality and enhanced safety, making it especially suitable for sports applications. In swimming goggles, Trivex performs well in both recreational and intensive use, where durability and resistance to mechanical stress are important.

In summary, the choice of lens material for swimming goggles should take into account prescription strength, frequency of use, and comfort expectations. Index 1.5 is a practical and economical option for lower prescriptions. Index 1.6 is the most versatile choice in terms of comfort and construction. Index 1.67 is intended for higher corrections where reduced thickness is critical. Trivex 1.53 is recommended for users seeking increased durability and safety during swimming activities.
