How to Remove Sun Glare From a Screen

Updated July 20, 2017

Glossy computer screens have always been popular. They make colours look richer and appear to pop out from the screen, and they are perfect for computing indoors or in lowlight areas. Unfortunately, their smooth finish makes them especially susceptible to glare from the sun or bright lights. Sun glare on a screen can be frustrating to deal with, especially in an office setting where you may not be able to move or adjust your monitor to reduce glare. Fortunately, there are a number of tips you can implement to reduce the impact of sun glare on your computer screen.

Adjust the monitor's position. Glare is caused by the sun or its reflection shining onto the screen and into your eyes, reducing the screen's visibility. Reposition the monitor so that it is not facing toward the sun or any surface that reflects the sun, such as a mirror. If you cannot move the monitor, try adjusting it up or down to see if the level of glare drops.

Reduce lighting in the room. Lower the amount of sunlight coming into the room and hitting your monitor's screen by closing the shades. In addition to sunlight, bright sources of light such as fluorescent light bulbs can also cause glare on your screen. Dim or turn these lights off or readjust your screen so that it does not face these lights.

Set the brightness on your screen to maximum. A lower brightness level means the light emerging from the screen has to compete with the light reflected by the sun to reach your eyes. By increasing the screen's brightness levels, you can overpower the glare effect and make it much less noticeable.

Build an antiglare shield. Find a piece of cardboard, a filing folder or any relatively rigid, flat item that can be easily cut. Tape it to the top and both sides of your screen such that it lies perpendicular to the screen. This will reduce the amount of light that reaches the monitor and causes glare. You can also purchase a collapsible shield for your screen that you can keep open when the glare is strong and closed when working in areas with less glare.

Purchase an antiglare filter for your monitor. These filters are generally removable and cover your monitor's screen completely. They work by reducing the incoming and outgoing light by a certain factor. For example, a filter might reduce light by 50 per cent. Thus, light emanating from the monitor would reach your eyes at 50 per cent of its original brightness, while light emanating from the sun would hit your eyes at 25 per cent of its original brightness, since it would have to pass through the filter twice before reaching your eyes. Anti-glare filters can be found in most computer supply stores and are also known as neutral density filters. More advanced antiglare filters may also limit the viewing field of your monitor to only a view degrees, making these filters useful for preventing coworkers from spying on what you're doing while at work.

Get an antiglare monitor. Certain screens are specially designed to reduce glare. Choose a high brightness screen with a matt finish.
