I have always wanted to be a pilot but I am red/green color deficient. I passed all other physicals and can easily tell the difference between red and green. I only discovered I had a deficiency after I failed the Ishihara Plates Test (the one with circles of dots with numbers). So I opted for Military Police instead of flight school. However, now color vision contact lenses and glasses are available with a 100% success rate after testing with the Ishihara Plates Test. Does this open any new doors for color deficient applicants in flight schools? I can't find anyone that has answers. Thank you.
According to FAA guide for Aviation Medical Examiners:
F. Color Vision Correcting Lens (e.g. X-Chrom)
Such lenses are unacceptable to the FAA as a means for correcting a pilot's color vision deficiencies.
However, you have the option of taking other tests for color vision. It would be better to talk with your physician or the medical examiner about this.
