With the development of space technology in China, many astronauts have very high requirements and must be very healthy. Because there are many unexpected dangers in the sky, the conditions for astronauts are very harsh, such as vision, weight and height. So some people ask why myopia can also be an astronaut, and astronauts don't need too good eyesight. It's actually quite simple. Astronauts also have non-professionals who can take contact lenses into space, so myopia can also be an astronaut. Let's analyze it. First of all, there are three kinds of astronauts, one is pilots, who mainly drive manned spacecraft, and the other is mission experts, who are responsible for repairing some obstacles in flight. The third is a load expert who collects things in space to do experiments. The first two kinds of people are professionals, while the latter are non-professionals. Only when they have the task of collecting things and doing experiments, are they allowed to go into space, because researchers have high academic qualifications and knowledge, and only when they go will they provide some valuable space mysteries for the country, which is also the reason why nearsighted people become astronauts.

Secondly, professional astronauts are selected through layers of screening, which is one in a hundred. Of course, people who are nearsighted can't be astronauts, because wearing glasses in space flight is very troublesome, which is not conducive to their own actions. Today, more and more people go into space frequently, and the space station in space has become a place for people to stay.

In a word, the progress of our country is obvious to all. Non-professional astronauts can wear contact lenses, which can help correct astronauts' vision problems. Therefore, from now on, many researchers and scientists can freely go in and out of space without the restriction of myopia, and do their part for the country and the people, and the people will not forget the contribution of astronauts to the country.
