Reading glasses also need refraction If the eyes are presbyopia or need to change "reading glasses", buy one on the street by the way, and more than half of the elderly people have not gone through the optometry procedure before wearing "reading glasses". Experts point out that this is very hurtful to the eyes. Uncle Li has been wearing reading glasses for many years, and his grandson accidentally broke his glasses a week ago.

It was very inconvenient to have no reading glasses, so the uncle went to a roadside stall and bought a reading glasses for 20 yuan. After wearing it for a few days, he felt that his eyesight was getting worse and worse, and he often felt dizzy. When I went to the ophthalmology department of the hospital, the doctor said that the problem was in the "reading glasses", and the power and interpupillary distance of the new "reading glasses" were not suitable for Uncle Li, so it caused uncomfortable symptoms.

In fact, it is very common for people like Uncle Li to wear "reading glasses" without optometry, and almost half of the elderly have not had optometry before getting glasses. They think that "reading glasses" are the same, and they don't need to be so troublesome about optometry, they can buy a pair to wear and even share the same pair of "reading glasses" with their husbands and wives.

Experts point out that the elderly have weak eye adaptability and more eye diseases, so the optometry examination of the elderly in the process of "wearing glasses" is more important. If you buy finished reading glasses without optometry, it is extremely harmful to your eyes. Long-term wearing of inappropriate "reading glasses" can cause great damage to vision, easily causing symptoms such as visual fatigue and blurred vision, and even leading to the transformation of the ciliary muscle, resulting in vision damage.

Experts remind that before wearing "reading glasses", you should first go to the hospital for a comprehensive examination of both eyes, including distance vision, near vision, refractive interstitium, especially to see whether there are cataracts, glaucoma and fundus conditions. Then the refraction determines the power and wears it.
