The distance between your eyes and the screen should be about 50 to 70 centimetres. keep in mind that, if you wear trifocals, bifocals or reading glasses, they may need to be changed to compensate for this positioning. Minimise glare on your screen by adjusting the lighting in the room or adding a glare filter to the screen itself.
Another way to reduce glare is to decrease the amount of white paper on the desk surrounding the computer.
remember to wipe dust off the screen periodically to make it easier to see. Also, make sure the screen is properly focused to reduce straining.
Because you need to blink less often while your eyes are fixed, it is important consciously to remind yourself to blink frequently or to close your eyes for a few seconds periodically while at the computer. This bathes the eyes in fluid and keeps them drying out. Finally, remember to take mini-breaks every hour or so, and to change your body position after them. That helps your back, too.
Push-Ups For Your Eyes
Since a fixed gaze causes most eye strain, the best way to avoid such strain is to do eye exercises.
Every 10 minutes: simply look away from the screen at something at least 6 metres away
Every hour: do additional eye exercises and stand up to move your neck and shoulders. Repeatedly change your focus from a near point to a far point.
