Glare appears on a computer screen when light from the surroundings reflects off of the screen’s surface. Some computer screens have a special coating to reduce glare.

An anti-glare coating reduces the bright, mirror-like reflection by scattering incoming light in many directions. A rough surface spreads the reflected light out, so less of it reaches the viewer as a concentrated glare. The coating does not need to absorb all the light or block the screen’s own light.
