I have a question for the Doc. and for the members. As a quick background, I've had numerous eye exams as a result of my PRK surgery from 2011 and have come up 20/20 every time and well within all SNA standards. Last year I was selected as a SNFO with the Marines. My OSO submitted a request on my behalf to switch from SNFO to SNA and we're waiting on the approval/denial. My OSO scheduled me to get my class 1 instead of class 2 flight physical, that way if the contract change was approved, I would be ahead of the game. Yesterday I had the first half of my class 1 flight physical at Andrews Air Force Base. I saw the eye doctor and went through the standard eye exam and again, my eyes came back as 20/20. They then had me hold a red lens over my left eye while the doctor held a single white light in front of me and asked how many lights I saw. As he moved it around from 3 to 6 to 9 to 12 o'clock, sometimes I saw one light and sometimes I saw two separate lights about a centimeter apart. The doctor then measured my eyes and it turns out that they, in his words, "move very, very slightly." He explained that my one eye compensated a little for the other but expressed that it was nothing to worry about so I believe him. At worst he said that the medical guys at Andrews would send me back to the optometrist again for re-evaluation. Just out of curiosity, how common is this result? The Doc said it was interesting that I sometimes saw 1 light and sometimes saw 2 making me think it wasn't too common. Has this happened to anyone on this forum who still went on to qualify with a class 1? Thanks for your replies.
