You didn't say exactly what you believe, but I think you are mistaken if you are claiming that the FAA requires _uncorrected_ 20:20 vision as a qualification.

"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."
