Can I get a first class medical with eyesight of -4.25/-1.00 diopters? I'm wondering if I'm able to obtain the FAA 1st class medical certificate with the power of -4.25 and -1 in my eyes. I heard that the difference between the two eyes must not exceed 2 diopters.
From the FAA's website



The key line is "with or without correction". So as long as your vision is correctable to the standards given you are good to go. You can find the full AME guidelines here is you are curious.
