The mask is a very important item of snorkel gear. It is the item that allows you to see the amazing world that lies underneath the surface.
Snorkel masks are used to protect the eyes from the water or any object that can harm you when diving. Since it is a vital item, it is important that you choose the best snorkel mask. The best kind of mask will be one that you fits right, feels right, doesn’t let water in, and allows you to see the underwater world clearly.
Choosing Your Mask
The most important aspect of any underwater mask is ability to see clearly. This means lens formation and measurement is the biggest decision you are going to make. You can get single, twin or multiple lens configuration. However, the lens shape, glass specification and special coating are all possible options. Single lens masks are more open because they do not have frames across the bridge of the nose. With single lens, it is impossible to replace prescription corrections.
Twin lens masks are compatible with replacement prescription lenses. They are easily fitted because you can remove part of the frame. Multiple lens masks have a window panel on each side
