What is Eyestrain?

Anyone who reads for hours works at a computer or drives long distances or focus certainly at the same point already knows about this one. It happens when you overuse your eyes. They get tired and need to rest, just like any other part of your body.

If your eyes feel strained, give them some time off. If they’re still weary after a few days, check with your doctor to make sure it isn’t another problem.

Computer and digital devices use

Extended use of computers and other digital devices is one of the most common causes of eyestrain. The American Optometric Association calls this computer vision syndrome or digital eyestrain. People who look at screens two or more hours in a row every day have the greatest risk of this condition.

Computer use strains eyes more than reading print material because people tend to:

  • Blink less while using computers (blinking is key to moistening the eyes)
  • View digital screens at less than ideal distances or angles
  • Use devices that have glare or reflection
  • Use devices with poor contrast between the text and the background

In some cases, an underlying eye problem, such as eye muscle imbalance or uncorrected vision, can cause or worsen computer eyestrain.
