There are many studies that associate prolonged computer use with eye strain and
discomfort. Ocular surface dryness (due to infrequent blinking) can result in symptoms. To
minimize this, you should follow the 20-20-20 rule: take a break every 20 minutes and look at an
object 20 feet away for at least 20 seconds. You can also change your computer display
brightness, increase font size and minimize glare with proper lighting.
