Our eyes were not designed to see well in water, and a diving mask provides an air space between the water and our eyes so that we can see clearly. For diving, a good mask is absolutely essential. It is the difference between a great diving experience and an average one. A good mask must fit well, not leak, and provide good vision underwater.
Difference Between Diving Masks and Goggles
Why do scuba divers wear masks that cover the nose and eyes, not just goggles that only cover the eyes? The reason is that the nose pocket of a diving mask is needed to compensate for increasing pressure as you dive deeper. The nose pocket allows the diver to blow air into the mask, equalizing the pressure.
Parts of a Diving Mask
A diving mask consists of a lens made of tempered glass, a double skirt made from surgical-grade silicone that holds the water out, and an adjustable mask strap.
A diving mask is made robustly. And it is more expensive than the children’s mask that you can buy in a supermarket.
