What does binocular ametropia mean

First: speaking of myopia, many people may suddenly realize that ametropia is myopia. It's just one of the symptoms of ametropia. At present, the rate of myopia in children and young people is high, which makes it one of the main symptoms of ametropia.

Second: hyperopia is often said to be hyperopia, which is also a kind of ametropia leading to blurred vision. Hyperopia generally can't see far or near clearly, so the eyes of hyperopia patients have been in the state of over regulation, which is easy to produce the symptoms of visual fatigue.

Third: the general nearsighted people go with glasses, sometimes the optician will tell you that a certain eye has slight astigmatism. In fact, astigmatism is also one of the symptoms of ametropia. In general, slight astigmatism has no obvious effect on vision, and can be corrected by wearing glasses. If the astigmatism is serious, it will have a great impact on vision, which can lead to severe symptoms such as sharp decline of vision and frequent fatigue of vision.

matters needing attention

There are many reasons for ametropia, among which genetic factors are very important. Of course, unreasonable use of eyes is also a reason that can not be ignored. Children in the period of growth and development do not pay attention to eye hygiene, such as reading and writing posture is not correct or the light is not good, resulting in the distance between the eyes and the book is too close, or reading time is too long, or walking and reading can cause eye fatigue, contributing to ametropia.
