While on holiday July 2013 I bought a genuine pair of Ray ban sunglasses as I thought, for not much less than the Amazon price, they seemed well made as you would expect. The guy in the shop kept telling me the importance of buying genuine glasses with good UV protection. I wore them for a few days and whilst on a visit to a nearby area, my son who has fake Ray bans was looking at the real thing in a different opticians. The owner of the shop invited us in and said he would show how fakes have little or no UV protection. He plugged a machine into the mains and placed my sons glasses under it and as might be expected, there was no UV protection. He then got a pair of his genuine glasses and these showed high UV protection. He then took mine and to everyone's surprise, there was no UV protection. His advice was to take them back to Goz optic. After a heated debate, my money was refunded and we left the shop. As we returned to our accommodation we had to pass Goz optic again and the other bloke in the shop followed us up the street in a confrontational manner, however I am not easily phased and I feel he took the hint and didn't pursue it any further. My advice would be to seriously avoid Goz optic, Hisaronu Turkey.
