Abstract: presbyopia is irreversible. The better the eyesight, the more obvious the symptoms of presbyopia will be. If you have headache, eye pain and other symptoms of presbyopia, you should go to a professional shop immediately to match presbyopia glasses., Myopia will presbyopia, “myopia will not get presbyopia. This statement is incorrect.” Xiong Ying, a myopic ophthalmologist at Beijing Tongren Hospital, told us that both men and women, myopia and hyperopia, will face presbyopia.

“Myopia will not get presbyopia. This statement is incorrect.” Xiong Ying, a myopic ophthalmologist at Beijing Tongren Hospital, told us that both men and women, myopia and hyperopia, will face the phenomenon of presbyopia.
The so-called “presbyopia” refers to the situation that older people gradually have difficulty in close reading or working, which is a phenomenon of aging human function. Xiong Ying said: presbyopia is inevitable. When young, the lens of people’s eyes is soft and elastic, which can thicken and thin at any time. It has an excellent adjustment function when looking at nearby things. However, with age, the ocular lens gradually hardens and thickens, reducing the zoom ability. Therefore, when looking at near objects, the close objects become blurred because the image cannot be fully focused when projected on the retina.
Some people have misinterpreted that people with myopia will not grow old when they are older. In fact, presbyopia can also occur in patients with myopia. Myopia is that you can’t see clearly from a distance. You have to wear myopia glasses to see clearly. When the age of presbyopia comes, you need to reduce the degree of the original concave lens (equivalent to adding a convex lens) and even take off your nearsighted glasses to see clearly. For example, if you used to have a myopia of 250 degrees and you currently have a presbyopia of 200 degrees, you only need a concave lens of 50 degrees when you look near. At this time, you can see things near without wearing glasses (because it is only 50 degrees myopia).
In fact, you still have myopia and presbyopia. It just gives people the illusion that you can read books and newspapers without wearing presbyopia glasses.
Presbyopia is irreversible.
Presbyopia is irreversible. The better the eyesight, the more obvious the symptoms of presbyopia will be. If you have headache, eye pain and other symptoms of presbyopia, you should go to a professional shop immediately to match presbyopia glasses. Wearing reading glasses (a convex lens) is the simplest and necessary method. Since the degree of presbyopia will change with age, the degree of presbyopia will also deepen. At present, there are two ways to match presbyopic glasses: one is to add 1 / 3 of the adjustment force to the degree of glasses for clear viewing of close objects; The other is to use the lowest mirror to see close objects. The practice of many old people has proved that the latter is better.
The principle of wearing reading glasses is to wear them as late as possible if you can still see close; If you can see at a low level, you don’t wear depth glasses. Generally, the eyes wear 75 ~ 100 degrees for the first time, and then increase by 50 degrees every year until the age of 70. When wearing fancy glasses, optometry should be carried out first to avoid that the degree of wearing fancy glasses for the first time is too large and falling into a deeper state, causing ciliary muscle degeneration and damaging vision. Therefore, people with presbyopia choose to wear appropriate presbyopia glasses, which is beneficial to eye health care and the convenience of life and work.
At the same time, Xiong Ying also said that hyperopia and old flowers are not the same thing. Hyperopia is ametropia, mainly manifested in unclear far vision, unclear near vision and visual fatigue. Hyperopia occurs since childhood. Presbyopia is a natural physiological aging phenomenon. With the decline of regulatory power, presbyopia will occur whether there is myopia or hyperopia from about 40 years old. It shows that the reading object can be seen clearly only by putting it far away. At a certain time, it needs a positive lens to help see clearly.
Take off the reading glasses “and rejuvenate”
