Leading Optometrist, Dhruvin Patel is a specialist in the impact of blue light on eye health - that is light produced by phone and computer screens.
Blue Light can make it harder to fall asleep and have an impact on the health of eyes
Researchers say exposure to blue light could increase the risk of damage to eyesight and make it harder to fall asleep.
Patel shared his tips for minimising the impact from blue light while working from home or using screens.
1. Work an arm's length from the screen
Fully extend your arm and work from a distance - looking from your eyes to the end of your fingertips.
Use this as a minimum distance to reduce the stress on your eyeballs.
Simply put, every 20 minutes, look away from the screen for a minimum of 20 seconds at least 20 feet away.
This will help to reset your visual systems and eye through any long periods of screen work.
3. Screen height
Height and level of your working screen can have a big impact on eye strain.
Research has shown that it is better for the screen to be located higher than the users' watching level - the middle point should be 5-6 inches below the straight line of the users' vision.
This makes the space between upper and lower eyelid more open, often resulting in dryness of the eyes.
Position the computer screen to avoid glare, particularly from overhead lighting or windows.
Use blinds or drapes on
