Myopic eye deformation

Myopia is a common disease in ophthalmology. With the popularization of electronic products and the increase of students 'schoolwork pressure in recent years, the incidence of myopia increases year by year. The occurrence of myopia is caused by abnormal development of the eyeball, such as excessive elongation of the eye axis or excessive enhancement of the curvature of the corneal lens. Therefore, after the refraction of external light through the refractive system of glasses, that is, the corneal lens, the focus does not fall on the retina but falls in front of the retina. This projection on the retina becomes unclear, resulting in decreased vision. Myopia is mainly manifested in blurred vision, especially when looking far away, it is relatively good when looking close. Myopia itself does not cause eye deformation, but myopic eye axis extension, it may cause the eye to look like a protruding eyeball. In addition, wearing glasses for a long time, because the weight of the glasses frame and glasses is relatively large, it will compress the nose root, that is, the position of the glasses nose pad is deformed, so that the eyes look deformed. For this situation, it can be prevented. For example, we can choose a lighter material frame and lenses, you can choose a lens with a higher refractive index, so that the lens will be thinner and the weight will be smaller, so that you can reduce the pressure on the nose pad and reduce the deformation of the eyes.
