A good mask that fits well is very essential for a great diving experience. It provides good vision underwater, protects the diver’s face in case of an accident, and makes it easy for the divers to adjust the pressure underwater. Sure, we can swim underwater with our eyes open, but it just feels different and our eyes are not designed to see well in water. Let alone that the design of the mask determines how, and how well, you can see underwater. Less airspace inside the mask makes for better peripheral vision.
