When people with myopia reach middle or old age, the hardness of the lens will gradually increase with age, and therefore, the manifestation of phakic vision will also gradually appear. In order to improve this situation, the requirement is to wear two pairs of glasses: the first pair of glasses is for myopia, which is usually worn when going out, and can improve the distance vision. The second pair of glasses is presbyopia glasses, which are worn for close reading and improve near vision. With these two pairs of glasses, you can correct your vision both near and far to meet the needs of normal life. If you feel that this is more troublesome, you can also consider surgical treatment, in which a multifocal IOL is implanted, which can meet the requirements of distance, medium and near vision at the same time, so that you do not need to wear glasses, and this method is also desirable.
