Abstract: because people with myopia don’t have to wear presbyopic glasses to see near objects, many people mistakenly believe that people with myopia will no longer be presbyopia. In fact, this is a misunderstanding. Presbyopia is a normal physiological phenomenon, and people with myopia are no exception. Only when looking at near objects, the brightness of myopia and presbyopia cancel each other, so sometimes you can see clearly without wearing fancy glasses., As the saying goes, “flower or not, forty-eight”. It means that the elderly are presbyopia, and the age of 48 is the critical period. So, does this saying have a scientific basis? This reporter recently interviewed Ning Junen, honorary vice president and ophthalmologist of Hebei Xingtai ophthalmic hospital., Experts say that with age, the function of various organs of the body begins to decline. By the age of 48, the most obvious manifestation is the eyes. In order to see the close target, people increase the curvature of the intraocular lens through the contraction of the ciliary muscle, so that the close object forms a clear image on the retina. This function of changing the refractive power of the eye in order to see the close object is called eye accommodation. In fact, when the human eye is 45 years old, the eye accommodation is weakened due to the hardening of the lens and the decline of the ciliary muscle function. Therefore, the normal human eye will have difficulty seeing the near object at this time. It needs to be a little farther away to see clearly. This is the early phenomenon of aging. At the age of 48, the adjustment force decreases further, and the objects near the vision become more unclear, suggesting the need to wear reading glasses for correction., Ning Junen said that because people with myopia don’t have to wear reading glasses when they see near things, many people mistakenly believe that people with myopia won’t be dazzled anymore. In fact, this is a misunderstanding. Presbyopia is a normal physiological phenomenon, and people with myopia are no exception. Only when looking at near objects, the brightness of myopia and presbyopia cancel each other, so sometimes you can see clearly without wearing fancy glasses., Presbyopia does not reverse. Ning Junen said that some old people find that they can read and report without reading glasses. They think that presbyopia is good. In fact, presbyopia will not be reversed. “If the presbyopia is getting better, it’s best to go to the ophthalmology department to check whether there is cataract. Cataract is that the lens is turbid and causes refractive changes after absorbing water, which is similar to myopia. This change just ‘offsets’ the degree of presbyopia and makes it possible to see near objects without presbyopia glasses. This performance is actually one of the early symptoms of cataract.”, Ning Junen also said that many people think that the matching of presbyopic glasses is very simple. Take a few pairs of presbyopic glasses and try them on. Just choose one. In fact, this practice is unscientific. It is recommended that the elderly go to a professional and authoritative glasses store or go to the hospital in advance to check the relevant data. After wearing reading glasses, they should be rechecked regularly, usually once every 2 to 3 years., Experts say that some simple methods in daily life can delay the arrival of presbyopia. For example, blinking often can exercise eye muscles and delay aging. Medlar cassia tea can clear the liver, brighten the eyes and nourish the liver and kidney. Take 12g of medlar and grass Cassia respectively, soak them in freshly opened boiling water and drink them frequently. In addition, you can also choose Chinese patent medicine, such as Mingmu Dihuang pill, Dendrobium luminous pill and so on.,
