Question

can we become an astronaut to use spects or lenses when we have bad eyesight?.....​

Answer 1

Explanation:

And eyesight, it turns out, is one measure of age. Approximately 80 percent of the current astronaut corps wears eye correction (i.e. glasses or contact lenses). ... As long as the astronauts' vision is correctable to 20/20, they're allowed to fly. Even Apollo veteran John Young took his reading glasses along on STS-1.
