We didnt have glasses made but my husband lost one of the little screws in the arm and we went to Top Charoen Optical and they fixed it free.I have Arnnets sunglasses which I love but they had quite alot of scratches on the lense the girl said she could put new lenses the same quality 15au dollars and they are great now.The shop is about halfway between Jung Ceylon center and Baumanburi hotel on the same side of the road .There are lots of opticians though I think there's another Charoen shop in Bangala road.Have a great holiday.
