Ask the MB: Johnny Depp's Sunglasses in Blow
--Rick
A: There were a handful of companies that marketed this aluminum frame in the '70s. The ones Depp is wearing are called the "Fast Back." They were pre-fabricated sunglasses with not very good lenses. As you can kind-of see (bottom pic), there are no openings in the frames to install a lens (typically metal frames open somewhere and are reattached with a screw). Replacing these lenses require what's called "cold popping," i.e., it's forced in. It may be OK for a sunglass non-corrective lens but may be tricky to "cold pop" certain Rx lenses.
