Dive masks have changed very little since Jack Cousteau first invented SCUBA and strapped on a tank in the 1940's. Sure the materials have changed and vast improvements have been made in comfort and seal, but the dive mask of today is still a flat piece of glass trapping air against your face. This flat piece of glass still causes refraction when light moves from water to air making items appear larger and closer than they are and greatly reducing your angle of vision. I can still remember as a new diver reaching for something only to have my hand pass in front of it by a good 12 inches. Well things are a changing. A company called Hydro Optics has hired some NASA engineers and developed and new type of dive mask that apparently gives you panoramic views 350% greater than traditional flat diving masks.
