I bought these new in the 1980s and now they are vintage, I am vintage too so it makes sense. I really liked and used them extensively in the 1980s and 1990s but then I started wearing spectacles and I gradually phased them out. I haven't used them at all for the last 20 years. I kept them well and they stood the test of time. I really don't have any use for them anymore and I'd rather pass them on to someone that can use them.
