Cheap, terrible lenses from Torga Optical

I got the worst lenses from Torga Optical in Greenstone. I went for an eye test as I was due for new glasses. I was then told about this 2 for the price of 1 frames. They first gave me a pair of glasses with the wrong prescription that could have messed up my eyesight terribly. When that was sorted, the lenses that were replaced cannot be cleaned well and one of the people working there even admitted that the lenses were terrible, second rated lenses. I am now using one pair as the other pair is useless!!
