My pilot's licence requires me to carry a spare pair when flying too. I
routinely have a spare pair in the car and carry a pair (sometimes two) in
my coat, but, with my eyesight, I would need one of the spare pairs to find
the main pair if I dropped them.

The only other ppl I know, still has good vision in both eyes. Can you
continue to fly with a cataract on one eye like can do when driving?
