I own 2 brands of eye glasses,Oakley and Ray Ban. I have prescription glasses and sunglasses for each brand. The pic you see is a S$600 dollars Titanium brown Oakley prescription glasses. The logo on both sides fell off after 1.5 years. The rubber grip on the nose bridge seems to be slowly disintegrating.The colour on the frame of my Oakley sun shades are also fading on certain areas. On the other hand, the one and only Ray Ban glasses that I owned and is broken now is because Faye snapped it when she was about one. The quality of the Ray ban glasses which are cheaper seem to be better by far. Well, the German immigrants to the US have a long history when it comes to eye glasses.
From now on, no more Oakley for me and I will continue to buy Ray Ban.BTW, people with 20/20 vision, you have no idea how lucky you are.
