Myopia and presbyopia are two different refractive states, and there is no conflict between them. Myopia is a condition in which the refractive state of the eyes exceeds the normal range due to unreasonable eye habits, so that seeing at a distance is blurred, but seeing at a distance is still normal. Presbyopia, on the other hand, is a degenerative disease that occurs with age. As we age, the hardness of the lens increases and the elasticity decreases, so the adjustment ability of the eye decreases, and the symptoms can be seen as a decrease in near vision, blurred when looking at near places, but better vision when looking at far places. If you are nearsighted, you will not be able to see clearly near and far after middle age, and at this stage, you need to wear nearsighted glasses when you look at far and presbyopic glasses when you look at near.
