Do you have more than one pair of sunglasses? Do you get a pair for cold weather, and, if so, how is it different from the pair you wear in warmer weather?

Also, do you think sunglasses for others make a good holiday gift? Or is it impossible to buy glasses for others? Or would you just give a gift card for that purpose? (Maybe that's best.)

Here is a site I found that allows you to send in a photo and get analyzed for sunglasses type. Thought people here might be interested in trying it out.

Would be interested in hearing your thoughts!
