There are pilots with only one eye, so a waiver is possible. It turns out
that the depth perception provided by two eyes is really only effective up
to 100 feet or so. At greater distances we use our experience to judge
distance, i.e., relative size, etc.

I'm thinking about taking flying lessons, but I have a condition in one
of my eyes that may cause me to fail the medical.

As I understand it, the 3rd class medical requires 20/40 in "each eye
separately". I have a condition in the optic nerve of my left eye that
limits its detailed vision. I still have good peripheral vision in that
eye, but I have trouble using it to read. With the standard eye test
charts, I have trouble with all but the largest letters. The other eye
is fine.

I have had this condition for several years and it seems to be
non-progressive.

Will this prevent my getting a medical certificate, or can I get a
waiver?
