Surface-provided divers typically use a full-face mask or diving helmet, but in some systems, a half-mask may be used. When the human eye is in direct contact with water rather than air under normal circumstances, the light entering the eye is refracted at different angles, and the eye cannot focus the light on the retina. By providing air space in front of the eye, the eye can focus almost normally. The shape of the air space in the mask can affect focusing ability slightly. Corrective glasses can be installed on the inner surface of the viewport, or contact lenses can be worn inside the mask to allow people with focus deficiencies to achieve normal vision.
