Best computer screens to keep your employees' eyes strong

One of the main causes of eye strain and fatigue is the amount of glare on the computer screen. Large amounts of glare increase the amount of eye fatigue, as well as the amount of strain on the eyes. Rounded computer screen surfaces tend to reflect more light, which causes glare on the screen. The best computer screen to keep your eyes strong is a flat computer screen. A flat computer screen can help lessen eye strain and eye fatigue, but a key factor is the placement of the screen and the setup of your work station.

Distance:
The closeness of the computer screen is one of the main reasons for computer related eyestrain and fatigue. The screen should be at least 25 inches from your eyes. It is difficult to set an exact distance because every individual is different. But one sure way to determine a safe distance is if you can not read the characters on the screen from at least 25 inches away, it is best to make them larger than bringing the screen closer. The entire viewing area of the screen should be at eye level or even better slightly below eye level. Viewing the screen slightly below eye level may help to reduce headaches and eyestrain. Eye-level placed monitors only allow one posture that is comfortable to both the head and neck. Maintaining the same posture for a long period of time is uncomfortable. When the head-erect posture causes the user to tire, the alternatives are limited. One alternative is flexing the neck but that results in the user looking out of the top of their eyes. Looking out of the top of your eyes at close objects is not comfortable, and bending the neck downward can be cause discomfort as well. But placing the monitor lower can increase the options for neck movement and posture. You can hold your head erect and look downward with a monitor at a low position. When that posture become tiring, you can alternate among a wide range of flexed neck postures that allow good visual performance and will not increase posture discomfort. Posture discomfort and neck strain can lead to fatigue and eyestrain. Try tilting the monitor back so that the top is slightly farther away from your eyes than the bottom. There is less neck discomfort if the monitor is low and tipped back rather than with the top tipped forward.

Lighting:
Ceiling suspended and indirect lighting are the best for overall visual performance and to reduce glare and reflections on the screen. Keeping the overall light level low is best, along with using individually controlled lights to supplement light as needed. Use blinds and shades to control outside light.

Performance:
Monitors running at low refresh rates may cause fatigue and eye discomfort in a shorter amount of time. The typical refresh rate for video drivers and monitors in Windows is a minimum of 60 Hz. A display at 75 Hz or better is best. The number of times the monitor can pass the beam over the full area of the display is the refresh rate. This rate can vary depending on the settings the user has on their computer and the capability of the video card that is driving the display. The screen color can also affect eyestrain and fatigue. To help lessen strain and fatigue use dark letters on a light background. A light background reduces the brightness difference between the screen and the surrounding background, which makes it easier on your eyes. Using a white or light background will reduce the difference in contrast between the screen and what is reflected off it.
