Funky, fresh and fun! The See-Line R330 Purple are a unique pair of prescription glasses. Narrow rectangular shaped lenses are rimmed in a durable but flexible plastic frame with faded purple and a matte finish. The corners extend slightly and are followed by spring hinges. The faded purple temple pieces with a matte finish are extremely flexible. If you're the kind of person who is a little rough on your eyewear, these are the ones for you!
