I highly doubt those are Rx... however this seems to be a trend amongst fatties that think they're either a.) unique b.) hipsters c.) quirky and cute and in most cases d.) all of the above. I've seen hideous glasses with no lenses. As someone who has had to wear glasses since I was 6 and contacts since I was twelve, I don't get it. Then again, I don't get a lot of what these things do.
