Is the eye nearsighted, really won’t you get presbyopia? Don’t be vague about these things!!

Abstract: the so-called presbyopia, that is, hyperopia, is that in the process of people’s gradual aging, the lens regulating function is also declining with aging. At this time, the focus of the object does not fall on the retina, and people begin to lose sight of the object.

many people think that myopia needs to wear concave lenses, while presbyopia needs to wear convex lenses. In this way, the subtraction of positive and negative just offsets. How can they be dazzled? Is this the case? What’s the matter with

and

? The so-called presbyopia in

and

, that is, hyperopia, is that in the process of people’s gradual aging, the lens regulating function is also gradually declining with aging. At this time, when the object focus does not fall on the retina, people begin to lose sight of the object gradually. Presbyopia is a normal aging phenomenon. Anyone may become presbyopia, but the time will vary from person to person. Some people will have the symptoms of presbyopia in their 30s.

is precisely because the focus of presbyopia falls behind the retina. Therefore, when people look at objects close to themselves, their eyes try to adjust the focus, which brings a huge burden to the eye muscles. At this time, as long as you take the objects far away or look at the objects far away, you can clearly reflect them.

and

as the saying goes, “if you don’t spend, you will be forty-eight”. Most people will have presbyopia when they are about 48 years old. There is a saying in life that people with myopia will not get presbyopia when they are old. The reason is that some people with myopia can meet the need of looking close without reading glasses in old age. In fact, this view is one-sided. In fact, people with myopia will still grow old, but the lens degree is different.

why do many people think that people with myopia are not easy to get old flowers?

this is because the imaging of myopia is just opposite to presbyopia, and the object focus falls in front of the retina. Therefore, myopia can only see the things near, and you need to wear glasses to see the things far away. When looking at nearby objects, the lens can be easily seen without any adjustment, which has the same effect as wearing glasses for people with presbyopia. It is precisely because myopic people can see nearby objects without glasses, so people mistakenly equate this phenomenon with “not easy to get old flowers”.

and

whether normal vision or myopia, presbyopia will naturally appear with the aging of the body. However, presbyopia symptoms are often silent and difficult to detect. Therefore, when you feel that you often have eye fatigue or unexplained headache, feel that you have difficulty reading and can’t see clearly without taking newspapers and magazines away, you should go to the golden sunshine vision health work room to test your vision as soon as possible. The choice of

and

reading glasses is very important.

and

reading glasses on the street often have the same degree of both eyes and fixed pupil distance, but the vast majority of the elderly have refractive errors such as myopia, hyperopia or astigmatism, and the aging degree of both eyes is different. If they are casually equipped with a pair of glasses, they will not achieve the best visual effect for the elderly, On the contrary, it will produce visual interference and eye fatigue.
