As Def said, they were made from the Papillion 2001 / S Model Sunglasses.. The lens were removed and replaced with a gel lens, making the actor's eyes more visible..
These replicas, were molded from the Original Papillion and screen used version, but a few changes were made.. For example, no writing, plus the screws on the Original were silver, these are black to blend in with the sunglasses.. They also have the proper UV lens so people can wear them as sunglasses, not just for costumes.. Though fans could replace the lens with the gel lens to make them the same as the Original series..
The Papillion company stopped making these years ago.. As mentioned, a lot of money was handed over to mold them and have these turn up a close to the Originals as possible for fans.. The company in China then did the dirty on the customer and started shipping these off to other sunglasses companies ( Which are where these come from ), before the actual costumer even got their first batch..
