Not everyone one can get away with wearing cheap sunglasses, and like Porsche stuff, bike, watches, is one of the other things that I collect. As a matter of fact, I have my very first pair of (for me at the time) high dollar sunglass on my desk, right in front of me, a pay of
Ray-Bans that I got in 1982
My eyes are pretty sensitive to the sun, and I have found very few pairs of cheap glasses that work for me (that doesn't mean that all high $$$ work for me either) Point is, if you like the look & feel of something and can afford, what is wrong with buying it??
