If you get a pair of glasses at a regular optical shop here in Hong Kong, it ranges from $200 - $800, up to $4,000 if you are shopping in Central or Admiralty and the optometrist nags you by telling you the arms of glasses are made from Titanium or whatever metal from the outer space, which can sustain thousands pounds of impact.
I used to have glasses around HKD700. Now? only around HKD300 :)
