Pollution is a big deal for Olympians this year, mainly because there's just too much of it in Beijing. Athletes will need to worry about the effects of air quality on their performance, but not just in the way you think. Hockey players are concerned that the smog and haze will inhibit their ability to see the puck clearly. And so Britain's women's team is trying out an interesting technique -- red contact lenses.

The red lenses work like sunglasses and will help the women's eyes cut through the glare and focus more clearly. They'll also limit the amount of time the players spend squinting or frowning, which will help prevent headaches and tiring. But I think these contacts will have another effect on hockey -- intimidation. Can you imagine going face-to-face with an opponent whose eyes look like this? Creepy!
