This coating is a filter for the harmful UV radiation. The coating is either put on the lens or is imbedded into the lens to protect your eyes for the harmful effect of the sun’s UV radiation.
This is an Ultra Violet absorbing filter that helps overcome the abundance of blue in outdoor photographs. Not really necessary in digital photography as the camera's white balance system adjusts for the colour temperature of the scene.
UV filters are individual compounds or mixtures to prevent ultraviolet (UV) light from coming through. UV filters are used in sunscreens to protect skin or in photography to reduce haziness or fogginess created by ultraviolet light.
