I'm also a
tall person,
whizkid, and I also have a tougher problem. My skin is rather
acidic. My last pair of glasses had to be replaced because the
frame was
eaten through. I washed them daily, but to no avail.
I ended up getting titanium-framed glasses. I've had the frame over two years, and they look as good as when I bought them. They have an antique warm brown/grey tone and a tortise accent. They've survived Thailand, kids and dogs. If you're looking for frames that will last and not bend, try titanium. I've never had to have these adjusted. They were an excellent investment.
