Lasik Helps U.S. Retain Pilots, Astronauts
The natural human aging process is in a constant war with the U.S. military and the National Aeronautics and Space Administration. Aging has always degraded the vision of Air Force pilots, Navy divers and NASA astronauts - and this has made it difficult for the respective services to retain them.
The government has always feared that eyeglasses and contact lenses could be broken or dislodged in the course of the service members' often grueling work, threatening life, limb and government property in the process. Even with the advent of Lasik surgery, the fear didn't subside.
