Flat-face CRTs have straight lines and a consistent focus across the screen, so your brain doesn't have to work overtime to compensate for the monitor's imperfections. You should also be on the lookout for refresh rates that are too low. Anything less than 75Hz can cause the screen to flicker and possibly give you a headache or eyestrain. It's also important to position the monitor properly. It should be at eye level and at least 24 inches away from your face.
Many computer users have their monitors positioned too low and too close.
Most of us lean into our monitors, instead of sitting straight in our chairs. That's a formula for neck pain and backaches. A little care taken now could save you hundreds or even thousands of dollars in future medical bills. Inc. All rights reserved.
