Does presbyopic glasses need optometry?

Presbyopia is normal with age. But when wearing reading glasses, many uncles and aunts have misunderstandings, thinking that it is enough to see clearly, so they buy them at the stall. The husband and wife use a pair of glasses and haven't changed them for several years. I don't know, there are many things about wearing reading glasses. Incorrect wearing methods will only make your degree deeper and deeper. Let's summarize the common situation of wearing reading glasses without optometry.

Myth 1: Buy reading glasses at will. Many middle-aged and elderly people are used to buying a pair of reading glasses at a stall. The price is cheap and the style is not bad. A few days ago, Mr. Zhang spent more than ten yuan to buy a pair of "reading glasses" and read newspapers happily with glasses every day. But after a long time, I get dizzy, headache, fatigue and irritability.

To this end, Dean Ma of Taizhou Eye Hospital pointed out that the refractive system of the eyes will change to a certain extent with the increase of age (such as the decrease of transparency and the change of refractive index). ), and there may be different degrees of decline in both eyes. If you buy a pair of glasses casually, not only can the elderly not reach the best visual point, but also visual interference will occur, leading to eye pain, dizziness, decreased vision and other uncomfortable symptoms. It is best for the elderly to go to the hospital for a comprehensive ophthalmological examination before wearing reading glasses, and then find out the refraction of both eyes after eliminating the possibility of eye diseases and determine the best glasses degree. Try to match lenses in hospital ophthalmology or regular optical shops, try them on for about half an hour after selection, and then process and finalize the design after feeling no discomfort.

Myth 2: Many people use a pair of reading glasses. After her stepmother became intimate with her lover, Ms. Liang also joined the ranks of reading glasses. She wanted to buy a pair, but she gave up the idea of buying reading glasses when she thought that there were ready-made ones at home. So a pair of reading glasses is used by three people for two generations, but every time I wear them, I feel particularly tired.

In life, many people don't pay attention to reading glasses, and it is very common for couples to use a pair of reading glasses. Dean Ma said that in fact, the couple's eyesight can't be the same, and there must be one party accommodating the other. As a result, the eyesight of the eyes is getting worse and worse, and the presbyopia is rising rapidly, making it more and more unclear. "Some old people often use the same pair of reading glasses with their wives. Even if the reading glasses are the same, it is unscientific to do so because of people's face and pupil distance. They are all different, and the glasses of the elderly should be used by special people. " Dean Ma said.

Myth 3: Aunt Chen's reading glasses have been worn for almost ten years, and now they look a little fuzzy, but Aunt Chen has been trying to save money. If she can't see clearly, she will add a magnifying glass to "take pictures".

To this end, Dean Ma explained that it is wrong for many old people not to change their lenses after they are equipped with reading glasses. With the growth of the elderly, the degree of presbyopia will also deepen, usually increasing by 50 degrees every five years. Once the reading glasses are not suitable, they must be replaced in time, otherwise it will bring a lot of inconvenience to the lives of the elderly and accelerate the degree of presbyopia. At the same time, the life of reading glasses is limited, and long-term use will cause scratches and aging of the lenses, reduce the luminous flux and affect the imaging quality of the lenses. Therefore, the degree of presbyopia changes with age, so it is best to have an optometry every three to five years, and don't wear shallow glasses for a long time.

Myth 4: Young people don't know how to read. Liu boasts that his eyes are particularly good, with a vision of 2.0. I don't know why, but I can see clearly from a distance recently, but it's blurred from a close distance. His wife said that he might be presbyopia, but Liu scoffed. "I'm only forty years old, how can I grow old so quickly!" "

Dean Ma said that with the growth of age, the eye's adjustment ability is getting worse and worse, and presbyopia around 40 years old is also a normal physiological process. Presbyopia has appeared. If you insist on not wearing presbyopia, it will aggravate reading difficulties and cause dizziness and eye swelling.
