Billy: My disposable contact lenses. They're great for camping!

Jennifer: Cool! Each contact comes in its own saline solution?

Billy: Yep. They're prescription contacts with UV protection.

Jennifer: Wow! How high-class...a new pair for each day...

Billy: You just pop'em in in the morning, take them out at night, and then throw them away. No cleaning!

Jennifer: Cool. So are you near-sighted or far-sighted?

Billy: Near sighted.
