On my experience I won’t have glasses made in Thailand again. I did it 2 times, first time at a top charoen pattaya tai, with an ophthalmologist prescription. As far as I remember glasses were cheap, about 3000 B. In the end glasses were uncomfortable to see with, I went to the shop to tell her and she told me everything was fine, I just had to get used to them. Next time I went to France I had new glasses made.
I tried a second time in the shop in front of the doughnut shop big c pattaya tai ground floor. I thought, maybe it was top charoen and I could have nice fashionable glasses for again 3000 B. I had a doctors prescription. The same thing happened, no problem with the frame, but the lenses were uncomfortable to wear.
I think they have low quality lens production.
