Learn something new! [Wearing glasses will make your eyes smaller?] How to solve it?

Do you need to wear glasses frequently after getting them? Will wearing glasses frequently cause your eyes to deform? Many people think that the reason their eyes become smaller and more prominent after wearing glasses is because of the glasses, but in fact, this has nothing to do with the glasses.

Eye deformation is related to changes in the eye axis

If the eye is compared to an optical instrument, then the distance from the cornea, the outermost layer of the eyeball that receives light, to the retina, the innermost layer that senses light, can be regarded as the central axis of the optical system, that is, the eye axis. The eye axis of a normal person is approximately

24mm. Generally speaking, for every 1mm increase in eye axis, myopia increases by 300 degrees.

Spend. Many patients with high myopia who wear glasses often have large eyeballs, and their eyeballs appear to bulge outward when they are not wearing glasses. In fact, this is not a deformation of the eyes, but the lengthening of the eye axis.

Eye deformation can also be a contrast illusion

Sometimes people feel that eye deformation is just an illusion of contrast. Suitable glasses will not damage the eyes. It is just that the eyes appear smaller when viewed through the myopic lenses. Once people are used to the shape of the eyes when wearing glasses, they will feel that the appearance of the eyes has changed when they take off the glasses. There is no need to worry about it. In addition, if the glasses are too heavy and press the base of the nose flatter on both sides, or if the frames are too small and press the skin on both sides of the eyes for a long time, you may feel that your eyes are deformed after taking off the glasses, but in fact this is also an illusion of contrast.

For common high myopia with protruding eyeballs, this is one of the characteristic manifestations of pathological myopia, and the inevitability of its occurrence and aggravation has nothing to do with whether or not people wear glasses. The so-called eye deformation of some children or teenagers is mostly caused by contrast illusion, so there is no need to worry that wearing glasses will cause eye deformation.

Therefore, wearing suitable glasses will not only not damage the eyes or deform them, but will correct the deficiencies of the eyes, improve vision, be beneficial to work and study, and also be beneficial to the long-term health of our eyes.
