Many people think that myopia is not a symptom of farsightedness, but this is not true, because the basis of the pathology of these two diseases is different. Myopia is a high refractive state of the eye caused by bad eye habits or congenital genetic factors, in which the distance vision is poor. Presbyopia is a degenerative disease, which is usually seen in middle-aged and elderly people, and is due to the increase in the hardness of the lens and the gradual decrease in the adjustment power after ageing, which leads to a decrease in near vision. Therefore, for myopic people in their middle and old age, they will be in an awkward situation, with poor distance vision and poor near vision. In order to improve this situation, you can improve your vision by wearing glasses, you need to wear two pairs of glasses, one pair of glasses for near use, that is, presbyopic glasses, can improve near vision; one pair of glasses for far use, that is, myopic glasses, can be used to wear when you go out at ordinary times.
