Myopia can also cause presbyopia. Presbyopia is a degenerative condition that occurs when people reach middle age, but some people develop it at an earlier age and some at a later age. For those who are nearsighted, it is possible that the symptoms will appear a little later than normal, but they will definitely appear. This is because presbyopia is caused by the hardness of the lens increasing with age, which leads to a decrease in the regulation of the eye, so that nearsightedness decreases, which is manifested by not being able to see clearly when reading at close range and preferring to put the target farther away so as to feel clearer and more comfortable. This condition is not conflicting with myopia and can exist at the same time. If myopia and presbyopia occur at the same time, you need to wear two pairs of glasses: one pair of myopia glasses; and one pair of presbyopia glasses.
