This family owned business just a short 10 minute walk from Lougheed Station. I found it after using Google search. Its in a Korean strip mall which is full of character! I showed up at 1100 am with my broken prescription sunglasses which needed laser welding repair. Within one hour i came back and my glasses were polished and fixed. Very efficient and inexpensive. It was only 50 dollars plus tax. I highly recommend Hannam Optical.
