Wait and see what the physical shows. It perfectly, even advisable, to see an eye doctor and get a thorough exam, but don't use it to decide your fitness for UPT. If the Flying Class I shows vision as disqualifying, then argue the point with a private eye doctor, consider one of the laser eye surgeries, etc. My nephew was DQ'd from the Naval Academy, but got the eye surgery, like his father, and his now a naval pilot.
