1, you can wear glasses for dizziness, don't delay.
When many people have blurred vision, they are unwilling to accept the fact that they are dizzy, and they will not wear reading glasses. Instead, they will have symptoms such as dizziness and eye swelling. Therefore, when dizziness symptoms appear, you should wear glasses in time. The degree of presbyopia is related to age. At the age of 45, you need to wear 150 degree presbyopic glasses, which changes with the degree.
2. Conduct a comprehensive examination and optometry of the eyes before glasses.
Some old people buy a pair of reading glasses in an optical shop or on the street to save trouble, which is wrong. Because the reading glasses bought directly often have the same binocular degree and fixed pupillary distance, many people have myopia, hyperopia and astigmatism, and the binocular presbyopia degree is different and the pupillary distance is also different. If you buy a pair of glasses casually, it will not only do great harm to your eyes, but also easily aggravate symptoms such as visual fatigue and blurred vision. Therefore, first of all, we should go to the hospital for a comprehensive examination of our eyes. After excluding cataract, glaucoma and some fundus diseases, optometry should be done to determine the pupillary distance.
3. Try it on for a while after glasses.
When listening, if you can see the smallest words in the newspaper at 30 cm, there are no symptoms such as font deformation and dizziness, which means that reading glasses are suitable; If you can see clearly, but you will be tired after watching for a long time, which means that the degree needs to be adjusted, then try it for a while.
