1. Avoid long-term continuous operation of computers and mobile phones and reading and studying. Be careful, don't wait until you feel tired, but take a rest every hour or so, at least 10 to 15 minutes each time. Then you should choose to look at the green plants or foreground outside the window during the rest, or do eye exercises to relax your eyes fully.
2. Keep a good sitting posture when using computer and mobile phone and reading. Keep a proper posture and let your eyes look down at the screen horizontally or slightly, which can relax the neck muscles and minimize the area of your eyes exposed to the air. Don't look at your mobile phone lying down, and don't look at your mobile phone and books in bad light. Especially in the vehicle, you can't stare at mobile phones and tablets for a long time.
3. If the eyes are dry and red, there is burning sensation or foreign body sensation. Heavy eyelids, blurred vision, and even eye pain or headache. Then you must stop at once and use your computer and mobile phone to read. Rest for at least half a month.
4. Reasonable diet and balanced nutrition. We can protect our eyes through diet and nutrition, so we have to mention that vitamin A supplementation is an important protector of our eyes. Because vitamin A can combine with opsin in eyes to form rhodopsin, which is a necessary substance for dark vision.
