Dry Eye and Your Computer

Computer users spend several hours staring at their monitor. They tend to ignore their normal blinking process, which is vital to tear production. Blinking becomes less frequent: about seven times per minute as opposed to a normal rate of around 22 times per minute. Fewer blinks lead to increased evaporation along with the fatigue and eye strain associated with staring at the computer monitor. Ideally, computer users should take short breaks every 20 minutes to reduce this factor. Also, adjusting the monitor so that it is below eye level will allow the upper lid to be positioned lower and cover more of the eye’s surface –again to reduce evaporation. Being more conscious of blink rate, air circulation, glare, and creating a more ergonomic work area can help reduce dry eye symptoms while working at the computer.
