More than a quarter have to enlarge the font (字体) size on their mobile phone so they can read it clearly and half say they’re forced to zoom in on images to see them clearly. Meanwhile, 28 percent regularly squint (斜视) at the screen — all of which are signs of presbyopia (老花眼).

“Our eyes are not designed to be fixed on a single object for a long period of time, especially smaller laptops, tablets or smart devices. They may feel uncomfortable, sore, tired and even start to itch or burn. In rare cases, dry eyes syndrome (综合征) can lead to more serious eye issues,” says Giles Edmonds, clinical services director at Specsavers. The good news is that there are some simple solutions to prevent eye strain, and preserve your eye health overall.

#1            : Follow the 20:20:20 rule, looking up from your screen every 20 minutes and looking at something 20 feet away for at least 20 seconds. Looking into the distance helps relax the focusing muscles of your eyes, which in turn reduces eye tiredness.

#2            : Change your screen settings to ensure that the brightness and contrast are balanced correctly, as well as making fonts larger. Also, be mindful of how your computer is positioned. Adjust your screen so it is 15-20 degrees below eye level and around 50-70cm away from the eyes and make sure your room is properly lit to avoid squinting.

#3            : Reflections on your computer screen can cause glare and lead to eye strain. Try reducing this by attaching an anti-glare screen to your monitor or laptop to avoid external light shining onto the screen. Glasses wearers can also have lenses (镜片) treated with an anti-glare coating.
