Frequently Asked Questions
Can you make any prescription in the diving mask?
Yes, we can put any prescription in the dive mask. We can make diopters for far distance, near distance or far and near distance 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.
Do you also make dive masks for the people who are using progressive or bifocal lenses?
Yes. For people who use progressive or bifocal lenses daily, we offer bifocal lenses. This option gives the user the best experience and a wide view for far and near distance.
A narrow range of medium distance, which we can find on progressive lenses, is not optimal for diving, while a wide dual-focus field offers more width when looking at instruments or a camera.
Can you create a diving mask with astigmatism (cylinder)?
Yes, we can! We deal with all astigmatic corrections and even the complicated ones that 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.
What is diopter?
A diopter is a unit of measurement of strength, or the refractive power of lenses. The higher the diopters, the more curved the lens is. It is written with minus or plus sign, as seen on your prescription.
What is the optical center?
Optical center is the point at which the sphere and cylinder power of the lens intersect.
What is astigmatism?
Astigmatism is an imperfection in the curvature of your eye’s cornea or lenses. Usually, the cornea and lenses are smooth and curved equally in all directions, which helps to focus light rays sharply onto the retina at the back of your eye. If your cornea or lensesare not smooth and evenly curved, light rays are not refracted (bent) properly. Astigmatism is prevalent and affects 75% of people.
Who needs bifocal lenses in a diving mask?
Bifocal lenses for underwater are suitable for people who are above the age of 40 and need a sharp vision also for near distance. Bifocal lenses are a common choice of underwater photographers and cameramen and everyone who uses diving instruments, meters or a watch.
You will improve the enjoyment of diving by adding the ability to focus up close again.
How do I get information about my diopter?
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 diopter data also from your glasses. Every optician has a measuring device called focometer, which helps to measure the power on your glasses.
What is the pupillary distance, or PD?
The pupillary distance or PD is the distance from the center of one pupil to the center of the other. This distance is different for each person. It is essential for accurate dispensing to place the optical center of the lens over the center of the pupil. Any deviation can induce prism, changing the apparent power of the lenses.
If PD is not accurate, you can have worse depth view, and you will have a hard time to evaluate the approximate range of the object. Headache is also quite common.
How do I measure my PD?
The best way is to visit an optician, an optometrist, or an ophthalmologist. In case you do not have this option, you can do it on your own, or someone else can do it for you at home. This option is the easiest but less accurate way. It depends on your measuring skills.
For home measurement, you need a ruler, which you can also print here. You will find information and step by step guide you on the link above or in the footer of our webpage.
Is it possible to order only a mask without optical lenses?
It is only possible to order a dive mask with corrective optical lenses. We do not sell individual masks.
