A new report on digital eye strain by The Vision Council in the USA says that people who wear contacts are four times more likely to experience dry eyes during or after screen time.
LIFESTYLE NEWS - With the festive season downtime behind us, many of us are back at work spending hour after hour staring at a computer screen.
And all too often, that means eye strain, irritated eyes and blurred vision, symptoms which can be markedly worse if contact lenses are involved.
Since just two consecutive hours spent behind a screen can affect your vision, disrupt your sleep patterns and in the long term, affect your general eye health, here are 10 tips to help you make 2017 a good year for your eyes.
Cut the glare
Any light reflection on your screen will strain your eyes. Don't use your computer or device where there's direct light, especially sunlight, on the screen. Put an anti-glare filter on your screen, and if you wear specs, put the same anti-reflective coating on your glasses.
Avoid harsh light
It's not only glare off your screen that can cause eye strain and irritation. Bright sunlight through a window, or harsh indoor light should also be avoided.
Check that your computer screen is between 50 and 60 centimetres from your eyes.
A bright idea
Your screen is not meant to be a light source; if it's lighting your dark room, it's too bright. Rather, the screen should be the same brightness as the environment around you.
Banish the blue
Blue light emitted from screens causes eye strain, makes it harder to fall asleep, and is even thought to contribute to macular degeneration and vision loss. Reduce it with blue light filter apps like F.lux.
Bigger is better
Set the text on your device or computer to a large-enough size that you don't need to strain your eyes peering at the screen. Three times larger than the smallest you can comfortably read is a good guide.
Go for contrast
High contrast is good, so opt for black text on a white background, or similar dark-on-light colour combinations.
Take frequent breaks
Give your eyes a break every 20 minutes. Looking off into the far distance for a minute or two will prevent focus fatigue.
Blinking good advice
Studies show we blink five times less than usual when staring at a screen, which leads to dry eyes and blurry vision.
Designed for comfort
A new report on digital eye strain by The Vision Council in the USA says that people who wear contacts are four times more likely to experience dry eyes during or after screen time. Some studies show that silicone hydrogel contact lenses are more comfortable than regular soft lenses.
