Frame: SI Black
Lens: Clear/Grey

I use these at work in the machine shop. They are very functional for this purpose. They are way more comfortable than generic safety glasses, opticaly perfect, and ANSI Z87 approved so the boss approves. Besides, if I have to wear eye protection, I'd rather represent the O than wear some generic crap.

Lens: Black/Clear

Army Issue in Iraq. I don't wear M-frames much but we are required to wear ballistic eye wear all the time so they are comfortable and have the O.

Lens: SI Array setup

Great lenses. The classic three colors that you can rely on for pretty much anything. Tragic that the SI arrays don't naturally come in sets where Hybrid S is a standard lens size, but hey...

I think of the lens tints in this way: grey for bright sunlight but light enough for shadow. persimmon for foggy to slightly inclement conditions. Clear for dead of night with the cygolight so you don't smash into a tree. Besides. I'm not one that's huge for iridium coated lenses for sport use anyhow. No, if I had a red+ lens while riding my bike, I'd be thinking too much about keeping my lens nice and pretty than paying attention to the tree trunks in my path. Classic Three are great for me.
