I had perfect 20/20 vision until my 40's. Then it started to fail, but slowly. First it was just reading glasses. And then "computer" glasses. Now, in my late 50's, I have tri-focals. I tried the progressives, but I suffered through a week of nausea and gave up on them. So I have true, three-line trifocals. I bought a pair of Serengeti sunglasses (looooong time fan of them) and had trifocal lenses fitted to those frames.

Last year I started riding a bicycle and needed a wrap-around set of glasses to keep the dust and such out. I found that almost any decent frame can be adapted to use prescription lenses. And yes, they are very pricey. I have 4 pairs of sunglasses (2 for riding and two for normal use) and 4 pairs of regular glasses that I use depending on where I'm at and what I'm looking at. Welcome to the world of corrective vision.
