DIVE MASKS
You need a mask to see clearly underwater. Your eyes must be in air to focus properly, but your mask creates an air space that you have to equalize . This is why your mask must enclose your nose- so you can blow air into it. It's also why you never scuba dive with goggles. You can't equalize them, so you would get a squeeze.
You need a good quality mask made specifically for scuba diving. Your PADI DIVE CENTER or Resort will likely have quite a few from which to choose, and assist you. To check for proper fit, you can place most masks gently against your face and inhale slightly through your nose. they should stay in place with light suction without pushing or twisting to make seal.
Among masks that fit, this feature are desirable:
>>LOW PROFILE- A mask that sits as close to your face as possible (but still fits) give you wider field of view. It also requires less air for clearing of water and equaling.
>> WIDE VISION FIELD - Beyond low profile, same mask have special shapes to accommodate more field of view. Same have side windows for peripheral vision.
>>SILICONE COLOR- Some divers like the open "feel" of clear silicone rubber; other like the reduced glare of black .
>>FRANE COLOR- you can usually match the rest of your kit.
A new mask needs some preparation. You may need to scrub the interior of the glass with a masks cleaner made for this purpose. This removes manufacturers apply. This chemicals that some manufacturers apply. These chemicals increase a mask tendency to fog. However, this is not true of all masks, so check manufacture literature for specific recommendations. Other than that, your main preparation is to adjust the strap. Fit it over the crown of your head, above your ears, with a snug but not overly tight fit. secure the strap locking device if it has one. Many masks allow you to put them on slightly loose, then tighten, for a perfect fit.
