Presbyopia is a physiological phenomenon. As we age, the adjustment ability of the eye lens slowly becomes weaker, and people in general can adjust quickly when they look far away or near, but the adjustment ability of presbyopia becomes weaker, and patients will experience dizziness, swelling and blurred vision after looking far away and then near, and this condition cannot be slowly recovered. At present, there are two main methods to correct presbyopia, one is to wear presbyopic glasses, and the other is surgical treatment. However, surgical treatment technology is not mature, so it has not been widely used, and the main treatment method is still wearing presbyopic glasses. The structure of presbyopic glasses is a biconvex lens, which can compensate for the lack of adjustment of the eyes and effectively correct presbyopia. If you need presbyopic glasses, you must go to a regular hospital for an optometric examination to clarify whether there are other eye diseases, such as myopia, hyperopia or astigmatism, and then increase or decrease the diopter of the presbyopic glasses according to the degree of presbyopia and the age of the patient. Although presbyopia cannot recover slowly by itself, if patients pay attention to protecting their vision and using their eyes scientifically, they can delay the development of the disease and avoid the deepening of the prescription.
