Concentrated tasks can cause tired eyes and blurred vision too as if you spend a long time using a computer or watching television, your eyes can become tired and your vision blurred. Using a computer does not cause permanent damage to your eyes. However working on a computer is a demanding visual task that can cause eye discomfort. If you have an uncorrected vision problem, this can make computer use uncomfortable and can lead to blurred vision and eye strain.

Whenever you concentrate on a computer screen or watch television, you tend to blink less often which can lead to your eyes drying out. This is made worse if you are in a dry environment, such as a heated or air conditioned office.

Prevention of eye strain
You can help prevent dry eyes and minimise the risk of tired or sore eyes while reading or using a computer. Tips include:
· Take regular breaks
· Look around at objects that are at different distances
· Try to blink often.
If this doesn’t help, consult an optometrist to determine the underlying cause of the problem and the best way to manage it.
