Because the functions of the human body will gradually deteriorate, the lens of the eye will also appear to age and weaken its elasticity, which is what we call presbyopia.
Is presbyopia a disease?
Xi Xiaoma stated in advance that presbyopia is not a disease, but a physiological change that occurs with age. For most people, whether they suffer from myopia, farsightedness, or astigmatism, presbyopia may occur.
The main reason for this is related to the lens, which will age and harden with age, gradually decrease its elasticity, and lose its ability to adjust, even if the ciliary muscle can contract normally, the lens cannot increase enough curvature. Therefore, when people with presbyopia see near objects, the light is focused behind the retina instead of on the retina, resulting in a blurry image.
Generally speaking, presbyopia will begin to appear around the age of forty, if the elders in the family in daily life, often see the distance clearly, see the near but blurry, the font is small when you need to take away or take off the glasses to see clearly, then it is likely that presbyopia has begun to appear, as a younger generation, what should we do?
How to deal with presbyopia?
Prescription of reading glasses
Reading glasses should be fitted in time if there is presbyopia, and you must not go to the stall to buy a 10 yuan casually, it is recommended to go to a professional institution for optometry glasses.
At the same time, it is not possible to wear a pair of reading glasses for a long time, because the lenses may have scratches and aging, resulting in a decrease in light transmission, affecting the imaging quality of the lenses, and accelerating the "presbyopia" of the eyes.
Progressive Invisible Glasses
Progressive Hidden Glasses are ** glasses designed for presbyopia and come in a variety of different designs. The lens spreads from the center to the periphery, progressively adjusting the sight distance to the three sections, so that the eyes can adapt to different target distances.
Binocular complementation
Binocular complementation, also known as monocular vision, is based on the principle of using different refractive brightness of the two eyes to achieve both the division of labor and the effect of coordination, so as to alleviate the symptoms of presbyopia.
The results of binocular complementation can be achieved through different methods, including laser surgery and implantation of a standard monofocal intraocular lens, which can be followed by an eye examination followed by the advice of a professional ophthalmologist.
