Yes these are for a Halloween Scence....I'm mostly looking a small quarter size lens with metal ring around it.....it doesn't have to be optical. I found a site that sold reproduction ones.....but they are now discontinued. Appreciate more suggestions.
You're prolly looking for a monocle. I need one too, for a Dapper Death static, but I'll likely just make one out of polycarbonate or something and some metallic tape for a Dapper Death. Come to think...my sister is in the lens industry and I might get a castoff from her instead...you could always rob an old pair of eyeglasses, or perhaps a new pair of cheapo reading glasses from the dollar store. The lenses can be ground on the edges to make them more round if you need to do that.
