Eye safety: Take a break from your computer screen
1. Give your eyes a break if you spend hours in front of a computer. Keeping your focus at the same distance for long periods of time is like holding your arms out for extended time â€” they will get exhausted. Fortunately, our eyes adapt quickly, so either take a break from the screen or focus on some distant poster, photo or scene that will give your eyes' muscles of accommodation a change of focus.
2. Remember to blink your eyes. Computer users seem to subconsciously feel that at any moment, their computer will crash and theyâ€™ll lose all their work, and thus are more prone to dry eyes because they don't blink enough. Take a few moments to close or blink your eyes consciously and this will relieve the symptoms of dryness. And donâ€™t worry â€” your work will still be on the screen!
3. Many computer screens emit electromagnetic radiation that may prove harmful to your eyes if there is no ambient or background light. Try to avoid working on your computer in complete darkness or very low light conditions.
