What about 400 degrees?

Myopia is a common disease in ophthalmology. After the eyes show myopia, vision will decline. The higher the degree of myopia, the more obvious the decline of vision. If there is 400° myopia in the eyes, naked vision is very poor, and even the largest letter on the eye chart cannot be seen. In this case, it will definitely affect normal life, work and study. Therefore, in this case, we must choose various correction methods to improve vision as soon as possible. only by maintaining clear visual quality can we effectively prevent eye fatigue. For myopia correction methods, two ways can be selected according to different ages. For minors, glasses or corneal contact lenses can be selected. If adults over 18 years old, surgical correction can be selected, such as excimer laser surgery and femtosecond laser surgery.
