Detailed explanation-1: -Viewing a computer or digital screen often makes the eyes work harder. As a result, the unique characteristics and high visual demands of computer and digital screen viewing make many individuals susceptible to the development of vision-related symptoms.
Detailed explanation-2: -Sit about two feet away from a computer screen to reduce eyestrain. Make sure the center of the computer monitor is slightly lower than eye level-four to eight inches. Use a matte screen filter (about $10) to reduce glare on your smartphone, computer screen, or tablet.
Detailed explanation-3: -Close blinds or shades, and avoid placing your monitor directly in front of a window or white wall. Place an anti-glare cover over the screen. Adjust your monitor. Position your monitor directly in front of you about an arm’s length away so that the top of the screen is at or just below eye level.
Detailed explanation-4: -Giving the eyes and body frequent breaks from computer work to reduce eye and muscle fatigue. Since prolonged computer use requires a person to sit in the same position for an extended period, taking time out to stand, stretch and look around will not only help muscles, but will also give the eyes a chance to relax.
