Laser Vision Enhancements

20/20 really takes to become an astronaut?
I read that, along with the many demands and qualifications, astronauts need have 20/20 vision. I guess it's pretty accurate, if not 20/20 after close to him .. Am I right? Also, I heard that NASA has special tests that can detect laser eye and other medical procedures improves … right? If they can or can not, to disqualify a candidate? Thanks
Here are the requirements for becoming an astronaut. http://www.nasa.gov/audience/forstudents/postsecondary/features/F_Astronaut_Requirements.html The basic requirements for a shuttle pilot: * distance visual acuity: 20/100 or better uncorrected, correctable to 20/20 each eye. For a mission specialist: * Distance visual acuity: 20/200 or better uncorrected, correctable to 20/20 each eye. NASA has approved LASIK eye surgery to correct vision. http://74.125.47.132/search?q=cache:fxVCnZAWgS0J:www.escrs.org/Publications/Eurotimes/08Feb/NASAapprovesalllaser.pdf NASA astronaut + + +20 / 20 + & cd uncorrected = 4 & hl = en & ct = clnk
