Don't know if you still need advice but I also recommend tai kwong and Raymond chan as mentioned several posts upstream as well We have bought maybe 10 pairs or so over many visits to Hong Kong of different styles and prescriptions generally in a day. The only issue we have had is getting glass not plastic lenses but we don't know if that is due to a time crunch. We are nak next month for a little longer visit so we are going to see if glass can be made. He is very reputable and great to work with.
