Hello torkimtay and thank you for your question.

Yes, astronauts wear both glasses and contact lenses in space.


"Astronaut Selection"
"Pilots must have vision at least as good as 20/50 and mission
specialists must have vision of 20/150 or better. With glasses or
contact lenses, astronauts? vision must be 20/20."

"Actually, I wear ear plugs just because it's noisy up here," Foale
replied. "If I had braces, they wouldn't be a problem, and lots of
astronauts do wear contact lenses."

"Massey, Although I don't have personal experience, I know that some
astronauts wear contact lenses. Others choose to wear glasses. To my
knowledge there are no adverse effects of wearing contact lenses in
space. Several experiments have been conducted regarding the wearing
of lenses both in the pressurized environment of the shuttle as well
as during EVA when one wears a pressurized space suit to go for a
space walk"

Susan Helms NASA astronaut
"MS-2, Payload Commander Susan Helms, answered a few of the questions
the crew has received by E-mail including "can the crew members who
require eyeglasses use contact lenses in microgravity" Lt-Colonel
Helms replied that contact lenses work well and using saline is not a
problem however cleanliness, particularly hand, is difficult to obtain
at a level necessary for cleaning contact lenses so they use
disposable lenses"

Thank you for your question, and if you need any clarification of my
answer, do not hesitate to ask prior to rating my answer.

Very best regards
