What kind of old light eye

summary

The elderly must be familiar with the symptoms of presbyopia. Basically, it can be said that as long as the elderly will suffer from this disease, but some people may be earlier and some may be later. Let's talk about what kind of presbyopia belongs to.

What kind of old light eye

First: the old light eye, people to a certain age, will not read the small words in the books and newspapers, or read for a while, the words will become blurred, or read for a long time, and then look at distant objects will be blurred. This is presbyopia, commonly known as presbyopia. The characteristic is that you can't read the small words in books and newspapers.

Second, the reason for the appearance of dry aging eyes is the gradual aging of the lens. With the increase of age (generally after 40 years old), the lens of the eye will harden, and the ability of the lens to change its shape and focus on nearby objects will decline, which weakens the adaptability of the eye. This phenomenon of lens stretching and elasticity weakening is called laoguang.

Third: the appearance of each person's presbyopia depends not only on their age and individual differences, but also on their original refractive state and work habits. Generally speaking, people who face their eyes squarely begin to have presbyopia at the age of 45, while those who have hyperopia or who are engaged in close work will have presbyopia earlier.

matters needing attention

For the elderly, if there is dry aging eye, you can improve the situation by wearing convex lens glasses. At the same time, remember to use your eyes reasonably. If you use your eyes for a long time, you can stand up and look far away, and then let your eyes relax.
