Earlier quoted context omitted.
Do you have a date when that policy was instituted? I've known a lot of air traffic controllers, and most of them wore glasses.
First result in google for "air traffic controller training" https://www.faa.gov/air-traffic-controller-qualifications Edit: I didn't take a stance on this topic, if you think I did, you are incorrect. I was simply linking the website that outlines the requirements instead of postulating as to what they were.
"With FAA order 3930.3B ATC vision standards were made similar to airman standards. With or without correction air traffic controllers must demonstrate 20/20 distant vision in each eye separately, 20/40 in each eye at 16 inches near vision, and 20/40 in each eye at 32 inches intermediate vision if they are 50 years of age or older. Glasses or contact lenses are permitted."
