Ok, a younger generation person, whom I know, got interested in being an Air Traffic Controller due to my flying, Oshkosh, and exposure to all that, and has been going to school for that; they recently went in for a physical for it, and to everyone's shock (including theirs) was diagnosed with mild color blindness- its apparently hereditary, but has been so mild it's never been caught before, and they've had eye exams- their vision has always been excellent. What came out was that they generally can distinguish between red and green, it's closer shades like grey-green and green can be difficult. They went to an eye dr. for an eye exam immediately, and they said it was "very mild". Is there a way to get past this to be an air traffic controller? They're kind of upset, they were really interested in the career, and in aviation- is there any hope here? The AME was helpful, (said they could get Class III medical) but Im thinking we need some help here to get this fixed.
