Eyes may feel tired after focusing intensely on a computer screen, reading, or driving for a long period. This is known as eyestrain. It can often be caused by using digital devices, e.g. computers smartphones and tablets.
Symptoms can include headaches, red, dry eyes, blurred vision, and pain in the neck, shoulder or back.
It can be caused by working in a badly lit environment (either too bright or too dim), failing to blink as often as normal, holding a digital device too close to the eyes. It is important to note that you cannot harm your eyes by using a computer, or worsen any eye conditions you may have, and there is no evidence that blue light from screens is harmful.
The following actions will help to keep your eyes comfortable while using a screen –
Taking regular screen breaks, known as the 20,20,20 rule. Take a break of at least 20 seconds, every 20 minutes, and look at something at least 20 feet away.
If you wear spectacles, to prevent tiredness, you may need to wear your spectacles a little more when using a screen.
Ensure the general lighting in your workroom is adequate but avoid glare on the screen itself. Ensure you have a display screen equipment assessment at work.
Eye drops can help, and check the air quality of your work area, as fans, heating and cooling units may cause eyestrain.
