Myopia, the more you wear glasses, the more convex your eyes are?

Abstract: even if our eye axis is elongated, it will not make our eyes feel convex, because our eyes have a certain space. After our eye axis is elongated, if there is enough space behind the orbit, Then the forward projection of the ocular axis (eyeball) is not obvious.

What is the pain of myopia? Every nearsighted friend has all kinds of slots to vomit ~ what’s inconvenient to wear glasses! Wearing glasses affects beauty! Wearing glasses is not suitable for sports… But what people say most is that wearing glasses will deform the eyes and make the eyes convex. It’s really ugly. Therefore, many beauties refuse to wear frame glasses in order to avoid convex eyes. They would rather not see clearly than wear glasses…

but is it really the disaster caused by glasses? Glasses said silently, I don’t carry this pot… Today Xiaobian refuted the rumor for glasses. The protruding eyes of myopia are really not caused by glasses!

why does myopia protrude?

if the eyeball is prominent, it usually gives people a sense of appearance. Most people with myopia are mainly axial myopia, and the axis of the eye will certainly become longer. For example, the length of ocular axis in normal people, The average is about 24 mm. If people with myopia increase by 300 degrees, the length of the eye axis will increase by about 1 mm.

the exophthalmos of myopia is really not caused by glasses.

Even if our eye axis is elongated, it will not make our eyes feel convex, because our eyes have a certain space. After our eye axis is elongated, if there is enough space behind the orbit, The forward projection of the eye axis (eyeball) is not very obvious. However, if the orbital space is relatively small and the eye axis is elongated, people will feel that the forward projection of the eye axis (eyeball) is more obvious.

Myopia will make the eyes convex, which is more a feeling of visual appearance. Because myopia glasses are concave lenses, the eyes of people who wear glasses will shrink. When they take off their glasses, they will feel significantly enlarged. In addition, people with myopia will make their eyes convex, which may also be affected by eyelids, nose bridge height, genetics and other eye disease factors.

can exophthalmos be improved by myopia surgery?

because the refractive power of the cornea accounts for 3 / 4 of the refractive system of the whole eye, as long as the curvature of the cornea is changed a little, the refractive system of the whole eye can be changed. Therefore, most of the current myopia operations are done on the cornea. Using excimer laser to cut corneal tissue is equivalent to making a lens on the cornea to change the corneal curvature, so as to achieve the refractive state of emmetropia. In principle, the completion of myopia surgery does not change the appearance of the eyeball, but if you don’t wear glasses for a long time after the operation, you will gradually get used to the phenomenon of exophthalmos, so many people will have this feeling. When you see someone who has completed myopia surgery for a period of time, the eyeball doesn’t protrude much.
