I got a pair in TST in HKG, the guy told me I was getting the best lenses made and the scratch resistant lenses and coatings..bla bla bla..........
Six months later they were dreadfully scratched. I took them to the local guy in my small town, and lady there was shocked that they were this scratched in 6 months. I kept the frames, got two pair from them for about the same price as I paid in HKG, have had zero problems with scratches........after 2 years. The other pair is unworn! Im done with HKG and glasses and watches and suits and shirts....... stay home and buy American!
