Why are Scuba & Swim Goggles are Needed
Light behaves differently in water than in air, distorting what you see. Particularly when you are swimming or diving, objects appear larger and closer than they actually are. This can hamper your hand-eye coordination. Swim goggles and diving masks work by providing a pocket of air in front of you that enables light rays to travel to and through your eyes in a more precisely focused way.
How to Prevent Fogging & Leaking
Fogging and leaking are common and annoying problems with both swimming goggles and diving masks. To avoid leakage, always try on goggles or masks before buying to make sure they fit snugly and comfortably. With masks, remember that tighter is not always better. Masks that are too tight might pull away from the face and release the suction.
Scuba Diving Masks
Scuba diving or snorkeling masks tend to be large and rectangular, rising high and across the forehead and dipping down low, almost to the bottom of the nose.
Most diving masks are made of soft silicone, which is hypoallergenic and resists deterioration.
Most have a double-flanged face seal to keep the mask watertight. Prescription diving masks work in one of two ways: The entire lens area is a prescription lens.
Swimming Goggles are similar to diving masks, but they are much smaller and usually round or oval in shape. They also fit closer to the eyes than diving masks. Goggles protect your eyes from the water and are sleek and unobtrusive so they won’t interfere with your speed and motion.
