Kelly Scott, Contact Lenses, and Glasses:some idle speculation

I commented earlier that sometimes Kelly Scott, skip of Team Canada, wears glasses; sometimes she wears contact lenses.

My memory may be faulty, but I think she was wearing contacts during her losses to both Sweden early in the tournament and again last night during the loss to the U.S.

I presume she thinks she sees better wearing contacts and wears them on the days when she is expecting to face her toughest opponents, and that's the reason for the correlation. But the causation could go the other way. Perhaps she is more comfortable with glasses and should wear them all the time on the ice.

Update: She wore glasses for the game with Norway. It didn't seem to help much for the first eight ends. But see this!
