I love these sunglasses. The first pair of "good" sunglasses I ever bought were a pair of Ray-Ban Wayfarers. I loved them then, and I love them now. They had to wear out, because the glass lenses are virtually indestructible. On any plastic lenses I've had, including some that cost twice as much as my RB2140s, the lenses get scratched, no matter how careful I try to be. These babies are built to last. They feel solid in every respect. They are comfortable, and the optics are absolutely the best available. I got these here on Amazon for an amazing price - cheaper than I can get them at the PX or AAFES online store. Couldn't be happier with the price, service, or product.
