I've had two pairs of Oakley sunglasses. One pair, M frames I bought in 1997 with two lenses. I wore them a lot, thought I didn't really like the style of them tbh, but I bought them because the retailer demonstrated how good/ tough the lenses were by firing an air pistol at them. The lenses did not crack, though I didn't really think anyone would be firing an air gun at me, I thought at the time they must be quite good gear to withstand that. It never occurred to me to fire a gun at any other makes of glasses. I sold them on
Ebay last year, well worn for £50.
Last year I was given another pair of the washisname jacket ones as gift, they are lovley, the frame are comfortable, sturdy, and stylish. The lenses seem to do the job very well indeed. A couple of weeks ago something it me on the lense, made a hell of a noise, not a mark. I'm not sure what hit me, a fly, stone, bee, it was hard enough to startle me though.
There are something's I will not compromise on as far as cycling is concerned and eye wear is one of them.
