nice choice of frame Lau, I had a similar style of frame before I changed them for thicker frames and updated lenses. Though I thought £250 is a little expensive, mines were around the 100 mark I think, but that was a couple of years ago.
I picked up this Gucci frame in Hong Kong for about £130 , which included new lenses for my old glasses as well

but thats just because my whole family goes to the same opticians so we have *massive* discounts on everything hehe
