Ten rings have nothing to do with good vision! Most of my athletes have myopic astigmatism

In the 2016 Rio Olympics shooting women's 10m air pistol final, Chinese player Zhang Mengxue won the gold medal with a score of 199.4, and won the first gold medal for the Chinese delegation. I believe that many people have doubts. On the court, I am wearing a sharpshooter of Yang. I have amazing eyesight and I have a very good eyesight. However, the actual situation is that there is no direct connection between "shooter" and good vision. On the contrary, due to excessive use of eyes, many people regard fatigue as serious, but rather myopia.

In general, shooting, archery and other projects, the target of the target is far more than 50 meters, even if the vision is good, for more than 50 meters project, the bullseye has become very very small. Athletes must concentrate on the bull's eye and maintain their balance. This requires very high eyesight and loss of vision.

The greatest feature of the human eye is the ability to recognize details, often expressed in terms of resolution of the angle of view, and is called vision. Shooting exercise is generally one eye closes one eye, so that the two eyes have different strength for a long time, artificially lengthen the eye axis, causing myopia or astigmatism; another possibility is that the vision produces a ghost.

Shooting champion myopia is a common international phenomenon. Therefore, many shooting athletes generally choose to wear glasses to correct vision, and make professional adjustments in terms of reflection and astigmatism.
