Many people believe that people with myopia do not have presbyopia. In fact, this statement is incorrect because as people with myopia age, a series of aging degenerative phenomena will occur in their eyes. In terms of the definitions of myopia and presbyopia, myopia: seeing close is clear, seeing far is not clear. Presbyopia: seeing near is not clear, seeing far is the same as before. For elderly people who are not nearsighted, they do not need to wear glasses to see far away, but only need to see near. Therefore, myopia and presbyopia can only offset the “near vision” part. When you look far away, you are still “nearsighted”. Therefore, when a nearsighted person wears fancy glasses, it is not only his age but also his nearsightedness that should be taken into account. Moreover, presbyopia is only 300 degrees at most, which can only offset the 300 degrees of nearsightedness of a myopic person. For example, if a person with six degrees of myopia is partially offset by presbyopia (250 degrees), he will still need 350 degrees of myopic glasses for near vision. In life we often see some nearsighted elderly people who take off their nearsighted glasses when reading and sometimes have to move the book again to the near or far side appropriately, because they have different degrees of presbyopia occurring on top of their nearsightedness. Presbyopia is related to the use of the eyes when you are young, the eyes are overworked, presbyopia will “report” in advance. The young, who do not want to wear presbyopic glasses, which requires more attention in general, do not always let their eyes in a fatigue state. First, to ensure adequate sleep, adults should ensure at least 6 hours of sleep per day, sleep before 11:00 each night to ensure adequate rest. Secondly, to let your eyes rest in between close work, generally 10 minutes. You can let your eyes leave the computer screen or books, look into the distance, do office exercises, eye exercises, activities, cervical spine, so long-term persistence, there will be benefits.
