I bought these babies a few months ago during a contract job as a school photographer. I had to wake up REALLY early every morning and there were some mornings that I just wanted to stay in bed. I saw someone wearing these glasses at a local natural foods store in yellow - the "I can!" color so I decided that I'd better wear a pair for such mornings. Now, I wear these glasses whenever I'm feeling pessimistic and Eeyore-ish. It might just be in my head, but I feel like they work! I mean, how can I be happy when everything looks like a vintage picture of summertime? When I wear them, I feel like I'm constantly in a Hipstmatic photo!
I definitely recommend everyone getting a pair. They don't only make everything around you look vintage... they make you look like you walked straight out of the 60s/early 70s. I can't even tell you how many times I've seen peace sign thrown or had "Hippie!" yelled at me as I walk by. If you want to buy a pair, you can find them on eBay for pretty cheap. I got my pair for something like $15.00, but I'm sure that you can find them cheaper!
