In the digital age, we are in front of screens almost all the time, whether for work, study or entertainment. Staring at an electronic screen for long periods of time often leads to eye fatigue, which can cause dry eyes, soreness, blurred vision and even headaches. There are a number of simple and practical steps we can take to effectively reduce eye fatigue.
- Regular rest
When we use electronic screens, the eye muscles are in a state of tension, so regular rest is very effective in reducing fatigue. Follow the "20-20-20" principle: for every 20 minutes of eye work, look 20 feet (about 6 metres) away for 20 seconds. These short breaks can help take your eyes off the focus of close vision, relax your eye muscles and reduce fatigue.
- Maintain good posture
Ensure that your eyes are at an appropriate distance from the screen, at least 50 cm is generally recommended. If you are watching a large screen, this distance should be increased. At the same time, maintain a correct sitting posture with your back straight and feet flat on the floor, avoiding prolonged head bending or twisting, which can reduce pressure on your neck and back and indirectly alleviate eye fatigue. If you find that you have to squint to see clearly at normal distances, it's time to upgrade your eyeglasses.
- Appropriate outdoor activities
Taking part in outdoor activities and exposing your eyes to natural light can help regulate your eyes' focus, improve their ability to adapt and reduce the fatigue associated with prolonged indoor use. However, to avoid periods of strong UV radiation, a pair of sunglasses or polarised glasses will help.
- A good sleep
Getting enough sleep is the key to reducing eye fatigue. A good night's sleep helps the eyes to repair and recover. Using a night mode or a warm-coloured screen, or wearing blue light blocking glasses to reduce the irritation of blue light on the retina, can help protect your eyes and promote sleep.
- Regular eye examinations
If you do not get relief from eye fatigue, see an eye specialist immediately. Do not use eye drops yourself as this may lead to drug dependence or worse, worsen the condition.
