Well yes, I wear them when I'm going fast. As soon as my eyes start tearing up, I'll put them back down. Normally though, I'm just cruising, going pretty slow and buttering around on the greens or hiking the same jib feature to get in some practice. Also, I prefer to get sunlight to my eyes as much as possible. It stimulates the ganglion which supresses pineal melatonin during the day which is an important part of circadian regularity, good digestive health (which in turn affects immune system) and plays a bigger role in our general health than most people might think.
At any rate, the Fire Iridium is a great color on bluebird sunny days and works well enough even on overcast. In low visibiilty, it might not perform as well as the non-iridium coatings, but that's a tradeoff you'll have to decide for yourself.
