Arctic lens challenge

Arctic lens challenge: CIBA Vision-sponsored contact lens wearing arctic explorer Gary Rolfe has completed a 400-mile solo journey with 12 dogs to an area marked unknown or unexplored on maps of Greenland.

Rolfe's contact lenses were challenged by temperatures of minus 50°C. Through his CIBA Vision lenses, Rolfe has also witnessed scenery such as the jungle of the Cockscombe Basin of Central America while on a three-month expedition, as well as the Canadian Arctic Archipelago.
