Will Wearing Glasses Make Eyes Smaller?
If eyes are compared to an optical instrument, the distance from the outermost cornea of the eyeball receiving light to the innermost retina where the light is received can be regarded as a central axis of the optical system, namely axis of eyes. The axial length of normal eyes is about 24mm. Generally speaking, if axis of eyes increases 1mm, the degree of myopia increases by 300 degrees. Many near sight people with high degree tend to have large eyeballs, they feel that their eyeballs protrude outward when they are not wearing glasses. In fact, this is not because eyes are deformed, but the axis of the eyes has become longer.
Myopia glasses are "shrink mirrors". When looking at the world through glasses, the object image will shrink. The higher the degree is, the more obvious this shrinking situation. When people are used to your eyes are "shrinking", one day when you suddenly don’t wear glasses, you will have an illusion of "your eyes are getting bigger". This illusion is often regarded as "bulging eyes/protruding eyes/eyeballs deformation. In addition, if glasses are too heavy to compress the sides of nose bridge or the frame is too small to compress the skin on both sides of the eyes, and the time is too long, you may feel "eye distortion" after removing the glasses, but in fact this is also a kind of The illusion of contrast.
The prominent eyeballs of high myopia is one of the characteristic of pathological myopia, and the inevitability of its occurrence and aggravation not related to whether to wear glasses. The so-called eye deformation of some children or adolescents is mostly caused by the illusion of contrast, no need to worry about wearing glasses will make the eye deformation.
Wearing proper glasses will not damage and deform the eyes, but will correct the deficiency of the eyes, improve the vision, which is beneficial to work and study, and is also conducive to the long-term health of our eyes.
