Mr. Li, 60, wore presbyopic glasses more than a decade ago, and the prescription has been increasing with age. But recently, Mr. Li’s eyes seem to have changed for the better, reading books and newspapers without the need to wear glasses. Can presbyopia really get better on its own? She came to the hospital and found that her presbyopia had been cured by an age-related cataract. The doctor said that when the cataract progresses, the optical density of the lens increases due to the hardening of the lens nucleus, which increases the refractive power of the refractive power, and the focus of the light entering the eye shifts forward to show myopia, thus making it clearer than before when looking at small words in the near distance. At the early stage of the disease, the clouding of the crystal is small and mild, and there are usually no symptoms, and one may sometimes feel double vision or multiple vision in one eye. After that, cataract gradually develops and starts to have a greater impact on vision, crystal clouding is more obvious, vision gradually decreases, and in the late stage, there will be serious visual impairment. Therefore, cataract patients should seek timely medical treatment to control the progress of the disease, and those who are serious need to find the best time for surgery to avoid blindness. Doctors remind that elderly people with cataracts should not use drugs at will, because some drugs for cataracts can promote the development of the disease for some people due to individual differences. Therefore, you should choose the applicable medication under the guidance of your doctor. It is better to wear sunglasses for protection during outdoor activities; you should also avoid excessive visual fatigue, use your eyes to the extent that they do not feel tired, pay attention to the correct eye posture and distance, and avoid reading and working in a dim environment for a long time. In addition to the active treatment of senile cataract, we should also pay attention to the diet. Some studies have shown that vitamin deficiency has a certain relationship with the formation of cataracts, so attention should be paid to the intake of sufficient vitamins from food.
