Frequently Asked Questions (FAQ)

Yes, we can put any prescription in dive mask. In dive mask we can make diopters for distance, near or for the distance and near at the same time (bifocals). All our work is custom so we can accommodate even the highest prescription.

In case your diopter is outside the range of diopters or you have specific parameters, please send us an email.

Yes we can! We deal with all astigmatic corrections and even the very difficult ones no one else can handle. The exact value and angles that are different for each eye are specified in the second set of numbers on your diopter prescription.

Astigmatism is an imperfection in the curvature of your eye’s cornea or lens. Normally, the cornea and lens are smooth and curved equally in all directions. This helps to focus light rays sharply onto the retina at the back of your eye. If your cornea or lens isn't smooth and evenly curved, light rays aren't refracted (bent) properly. Astigmatism is very common and affects 75% of people.

Yes. For the users who use progressive lenses or bifocal lenses on daily use, we offer bifocal lenses. This option gives the user the best experience and wide point of view for far and near distance. 

Bifocal lenses under water need those people who are more than 40 years old and need a sharp vision for near. Very often bifocal lenses choose underwater photographers and cameramen and everyone who uses diving instruments, meters or an hour.

Your enjoyment of diving will be improved by adding the ability to focus up close again.

The diopter is a unit of measurement of strength, or refractive power of lenses. The higher the diopters, the more curved the lens is.

The point at which the sphere and cylinder power of the lens intersects.

The information about your diopter is written on the prescription of your eye examination. You can ask for information about your optical values at your optician or doctor.

You can get your dioptre data also from your glasses. Every optician has a measuring device called focometer, which helps to measure the powers on your glasses.

The Interpupillary Distance or PD is the distance from the centre of one pupil to the centre of the other. This is different for each person. It is essential for accurate dispensing to place the optical centre of the lens over the centre of the pupil. Any offset can induce prism, actually changing the apparent power of the lens.

If PD is not accurate you can have worse depth view and you will have hard time evaluate approximate range of the object. Headache is very common.

The best way is if you go to the optician, optometrist or ophthalmologist. In case you don’t have this option, you can do it on your own or someone can do it for you at home. That’s the easy way but less accurate. It depends on your measuring skills.

For home measurement you need a home ruler or you can print our paper ruler here

Information about our paper ruler and step by step guide you will find on the link above or in the footer of our webpage.
