What are the causes of strabismus in humans?

I have congenital squint. The reason is just the constructor crashed during my assembly. In addition to strabismus, poor vision is often included, I was no exception, but my parents did not leave everything as it is and with the help of doctors, vision became better than most people. However, only one eye is constantly working for me, while the other works half-heartedly, giving out only a peripheral picture. This is a problem of the brain or nervous system, it is simply difficult for me to concentrate and "turn on" both eyes at the same time. But when shooting at a shooting range, you don't need to close one eye

Due to the fact that for a long time my vision on the left eye was -1.5, and on the right - normal, the main load was on the healthy eye and I had an increased risk of developing strabismus. So far so good. One of the possible reasons: too much strain on one eye.

Dear Vladimir! The causes of strabismus are varied. This can be the presence of farsightedness or myopia, when, due to a violation of refraction, different muscles receive an increased stimulus to focus on an object. Also, strabismus can be in neurological diseases and brain pathology, injuries, stressful situations, after some infectious diseases. To clarify the diagnosis, we recommend that you contact an ophthalmologist
