Abstract: some people think that wearing glasses for a long time will cause exophthalmos, which is also a misunderstanding. Eye deformation is often due to the compression of the bridge of the nose by wearing frame glasses all year round. After taking off the glasses, it will give people an illusion of eyeball protrusion.
people who often need to wear glasses will have such a question: will the degree of glasses be deeper and deeper? Ophthalmologists said that this is actually a misunderstanding of myopia glasses. Wearing appropriate glasses is only beneficial and will not affect the degree of eyes.
first, we should understand why myopia is formed. In addition to internal factors such as heredity and development, it is mainly due to people’s excessive use of eyes for a long time, so that the internal and external muscles of the eyes are in a tense state for a long time and can not rest. Over time, the eye axis becomes longer, the object images can not converge on the retina, and the distant objects can not be seen clearly. Myopia glasses can move the focus of the object image backward through the principle of concave lens, so as to correct vision. Therefore, from the original explanation, wearing myopia glasses will not lead to the deepening of myopia.
then why are some teenagers getting deeper and deeper after wearing myopia glasses? In fact, there are two reasons. One is caused by the physical development of teenagers. During the growth process, the ocular axis is also developing, which increases the anterior and posterior diameter of the eyeball and increases the degree of myopia; The second is that the predisposing factors of myopia have not been relieved.
glasses are worn more and more deeply because they are not properly equipped. Teenagers in the development stage have strong eye adjustment ability. If they do not undergo formal medical optometry and there are errors in astigmatism axis and pupil distance, the degree of glasses they wear is likely to be higher than the reality, which will cause visual fatigue and cause more and more myopia. In addition, bad eye habits can also cause vision loss, especially the use of electronic products such as mobile phones and tablets, which makes teenagers use their eyes too much.
and others believe that wearing glasses for a long time will cause eyeball protrusion, which is also a misunderstanding. Eye deformation is often due to the compression of the bridge of the nose by wearing frame glasses all year round. After taking off the glasses, it will give people an illusion of eyeball protrusion. Moreover, high myopia itself will bring the problem of prolonging the anterior and posterior diameter of the eyeball, which is manifested as exophthalmos from the appearance, which has nothing to do with wearing glasses. Normal wearing glasses for correction also helps to slow down the phenomenon.
Nanchong oriental hospital ophthalmology warm tips: how to wear glasses scientifically? It is suggested that those with a degree of more than 200 should wear it often, which will help to correct myopia and alleviate eye fatigue. If myopia is within 200 degrees, you can wear it when necessary. In addition, the most important thing is to go to a regular hospital for scientific optometry and choose appropriate glasses.
