Diving masks and swimming goggles

People generally wear scuba diving masks and swim goggles when swimming, diving, snorkel or other explore underwater. Light travel condition in air is different from that underwater. Objects watched underwater are larger and closer than they actually are. In addition, light rays can not travel effectively from eyes to target object through water. Masks and swim goggles provide a chamber of air in front of the eyes that enables the eyes to see things clearly and correctly. This is the reason why people need masks or swim goggles underwater.
