Are you in need of a new pair of glasses? Why buy them from the eye doctor when you can purchase a pair that used to belong to a celebrity? Perhaps Ewan McGregor, or Michael Caine?

A number of stars have donated their specs to help reduce global blindness. They've given their glasses to Sightsavers International, which is auctioning off the glasses to raise money for the cause. The auction started today and will run through Monday, August 25.

All glasses began with a starting bid of just £15, and most come with an autograph from the celebrity. When else are you going to have the opportunity to see things the way George Michael sees them, all while helping a good cause?
