My clip-on sunglasses were getting so scratched up that they were becoming useless. and then I lost them entirely a few days ago. So yesterday, after my doctor's appointment, when I swung down to clear the PO Box, I stopped by a Walgreen's and bought a new set. I couldn't find the same kind of clip-on that I'd used before, so I bought a "slip-over" rather than "clip-on" set. I'm much happier with these. They include "wings" that shade my eyes from the side as well as the front, which is an improvement. The only bad part is that because they aren't clip-on with a hinge, they won't be as useful in situations when I'm driving in and out of glare situations where I need to use the shades for a short time, then flip them up, then flip them back down again. Still, it's good to be able to be able to have proper shades that I can actually see through again.
