How can you tell if there is something wrong with your eyes?

Apart from optometry in the hospital, a simple way to distinguish true myopia from pseudomyopia is to hang an international standard eye chart at a distance of 5 meters, first determine the vision, and then wear 300-degree reading glasses to see the distance, and a foggy scene will slowly appear in front of you. After half an hour, take off your glasses and check your eyesight. If your eyesight is enhanced, it can be considered as pseudomyopia. If your eyesight is still declining, you can do it once a day and repeat it for three days. If your eyesight still hasn't improved, it can be confirmed as true myopia. In order to prevent myopia, please pay attention to:

1, develop a good habit of using your eyes, keep a correct posture when reading and writing, keep your eyes at a distance of about 30cm from the book, and don't read when walking, riding a bike or lying in bed.

2. The lighting in the study and work environment should be moderate, and there should be no glare or flicker. The blackboard does not reflect light. Don't read or write in the sun or in the dark.

3. Check your eyesight regularly. For myopia diagnosed by optometry, it is necessary to wear appropriate glasses, maintain good eyesight and normal adjustment and assembly.

4. Strengthen physical exercise, pay attention to nutrition and enhance physical fitness.
