I'll keep that in mind next time I get glasses. But, these are
prescription shades and only half a year old.

Mary, who is far-sighted, had prescription reading sunglasses made for
flying, with a gradient tint. The bottom half -- the prescription part --
is clear. The top half -- the sunglass part -- is non-prescription. The
split between clear and prescription is right at the top of the panel, as
you're looking through the glasses -- perfect for flying.

I also have a pair of gradient sunglasses, but I am near-sighted. The whole
lens is prescription, just clear at the bottom to make seeing the
instruments easier.
