Students Using Computers & Eye Care Tips
Have the child’s vision checked to ensure that the child can see clearly and comfortably, and to detect any hidden conditions that may contribute to eye-strain. When necessary, glasses, contact lenses, or vision therapy can provide clear, comfortable vision, not just for using the computer, but for all other aspects of daily activities. Strictly enforce the amount of time that a child can continuously use the computer. A 10-minute break every hour will minimize the development of focusing problems and eye irritation caused by improper blinking. Also consider shorter, more frequent breaks.

Reduce the amount of lighting in the room to match the computer screen. Often this can be simply done in the home. In some cases, a smaller light can be substituted for the bright overhead light, or a dimmer-switch can be installed to give flexible control of room lighting. In other cases, a three-way bulb can be turned to its lowest setting. Carefully check the height and arrangement of the monitor. The child’s size should determine how the monitor and keyboard are positioned. In many situations, the computer monitor will be too high in the child’s field of view, the chair too low, and the desk too high. A good solution to many of these problems is an adjustable chair that can be raised for the child’s comfort, since it is usually difficult to lower the computer monitor. A footstool may be necessary to support the child’s feet. Carefully check the lighting for glare on the computer screen. Windows or other light sources should not be directly visible when sitting in front of the monitor. When this occurs, the desk or computer should be turned to prevent glare on the screen. Draw curtains or blinds to reduce window lighting. Sometimes glare is less obvious. Holding a small mirror flat against the screen can be a useful way to look for light sources that are reflecting off of the screen from above or behind. If a light source can be seen in the mirror, the offending light should be moved or blocked from hitting the screen with a cardboard hood (a baffle) attached to the top of the monitor. In addition, the American Optometric Association has evaluated and accepted a number of glare screens that can be added to a monitor to reduce glare. Look for the AOA Seal of Acceptance when purchasing a glare-reduction filter.

Children have different needs to comfortably use a computer. A small amount of effort can help reinforce appropriate viewing habits and assure comfortable and enjoyable computer use.
