When considering an anti-glare computer screen, look for one that is made to fit the size of monitor that you have and keep in mind any secondary benefits it can provide. There are adjustable screens that can be used to fit a wide range of monitors, though it is often better to choose one meant for your specific screen size. It is important to consider the type of glare that you want to eliminate and choose an appropriate screen. Some models of anti-glare computer screen can also provide secondary effects, such as filters to reduce visibility from the sides of the monitor.
An anti-glare computer screen typically comes as either a framed object that connects to your monitor or as a thin piece that is overlaid directly onto your screen. Consider both of these options, as they can have different strengths and weaknesses. If you want an anti-glare computer screen that is a secondary piece of equipment that fits onto your monitor, then choose one that is the proper size for your display. It is also important to consider the type of monitor that you have, and find one designed for either a Cathode Ray Tube (CRT) or Liquid Crystal Display (LCD) as appropriate.
There are some screens that are a thin sheet to be placed directly onto your monitor's viewing surface. You should still consider if you have a CRT or LCD screen, as different models of anti-glare computer screen may be designed to function with only one type. There are some models that can work with both, as well as reversible screens that can function with matte or glossy monitors.
If you need an anti-glare computer screen to block out light around you, such as sunlight for using a laptop outside, then look for one designed for this purpose. Many screens are developed to reduce the radiation output and glare from fluorescent lights around a computer monitor. This helps decrease eye strain for computer users in this type of environment, such as an office that uses these lights. Such models may not work well for sunlight, however, so look for one that meets your specific needs.
As you choose an anti-glare computer screen, consider any other benefits that certain models may provide. Some screens, for example, can use filters to reduce visibility from angles other than directly in front of a monitor. If you work in an office and have a large display that passing associates might be able to see, then this type of filter can help increase your privacy.
