Scuba Diving Masks

Scuba diving or snorkeling masks  tend to be large and rectangular, rising high and across the forehead and dipping down low, almost to the bottom of the nose.

Most diving masks are made of soft silicone, which is hypoallergenic and resists deterioration.


Most have a double-flanged face seal to keep the mask watertight. Prescription diving masks work in one of two ways: The entire lens area is a prescription lens.

Prescription lenses are inserted separately between the mask face shield and your eyes. If the dive mask comes with prescription lenses, it can be made to your specific measurements and correction.


Also, masks are available pre-made with prescription lenses that have an equal correction for nearsightedness or farsightedness for both eyes. Although these pre-made lenses don't correct astigmatism, most people who need corrective lenses can see well enough with them in most underwater situations. But if you have a lot of astigmatism, this solution may not be for you.


Alternatively, some diving masks have a fixed lens area in the front that allows an insert containing custom-made prescription lenses to slide in behind it. Prescription lens inserts are especially handy for contact lens wearers, because the same diving mask can be used depending on your choice of vision correction.

If you wear your contact lenses for a dive, you don't need to use the prescription insert. If you prefer not to wear your contacts, you can slide in the insert for a clear underwater experience.


Keep in mind that not all contact lenses are suitable for diving, and swimming or diving while wearing contacts can cause problems. Gas permeable lenses (GP lenses) can "dig in" to the eyes below certain depths because of pressure, and soft contact lenses can collect waterborne organisms, become contaminated and cause eye infections.

This can happen in swimming pools, lakes, rivers and the ocean.
