You can make sure you keep your eyes healthy by following these tips.
Dry-eyes
When staring at a computer screen we blink up to 66% less than usual, so dry-eyes can be a common problem when using a computer. Having dry-eyes can cause eyestrain and, if severe enough, can even lead to loss of vision because the cornea can become scarred.There are several things you can do to keep your eyes moist and reduce eye strain. The 20/20/20 rule suggests that for every 20 minutes you stare at your computer screen you should spend 20 seconds looking at something 20ft away. Alternatively you can try to consciously blink your eye more often or close your eyes for 20 seconds every 30 minutes. If the condition persists you may want to consider buying lubricating eye drops.

Monitor
Make sure your monitor is set up correctly to minimise eye strain – ideally it should be about an arm's length away from you with the top of the monitor a couple of inches below your eye level. Tilting the monitor slightly upwards will also help ensure your eyes don't have to strain to focus on the screen.Adjust your brightness settings so that it's roughly equal to the brightness around it. If there are differences in brightness you may suffer from headaches as well as vision fatigue. Any distractions on your screen will require your eyes to work harder in order to focus so keep your screen clean and free of smudges and dirt, and eliminate glare from windows by using blinds.
Font
If you struggle to read the text on your screen you should increase the font size or, when possible, change the font you're working in. Some serif fonts may take you longer to process – this can cause you to stare even harder for longer, increasing the risk of eye fatigue. Arial and Verdana are two fonts that are particularly easy on the eyes thanks to the wide spacing between letters and crisp characters.
Contact lenses and glasses
Some people will find that wearing contact lenses increases the chance of having dry eyes. Special eye drops designed for contact lenses wearers can be used to keep your eyes moist throughout the day.

If you wear glasses you may find that an anti-reflection coating helps you deal with unwanted light reflections on your lens, which makes viewing the computer screen easier. Meanwhile, some people that wear varifocal or bifocal glasses have difficulty focusing on the computer screen because it is at an intermediate distance – further away than if you were reading a book, but not exactly in the distance. Single prescription glasses that are used exclusively for computer work should solve this problem.
Opticians
It's recommended that you visit an optician at least every two years, although if you are struggling to see correctly or are experiencing pain you should visit an optician immediately.
