The ecological climate of Bejing has been throwing curveballs at Olympic contenders this week. The first of these is a problem with glasses with beach volleyballers apparently fogging up during games.
One player, Phil Dalhausser, of the US national volleyball team, spoke about the situation on Monday: "The lenses fog up because of the humidity, so you can't wear the glasses without popping out the lenses."

There are some lenses that will help the athletes, however, and these come in the form of red contact lenses.
The coloured lenses are being used by British athletes to help focus in the Bejing smog.
According to reports, the British woman's hockey team has been wearing them in games, which is helping them see the fast-moving pucks on especially smoggy days.
