These fab vintage reading glasses are made of faux tortoise shell and are "cat" shaped, with lilting corners studded with aurora borealis rhinestones and metal stars. The sides also have rhinestones. The glasses measure 5-1/4 inches across the tops, and the lenses (which you would need to replace with your own prescription) are 5/8 inches tall. Some of the rhinestones have darkened, and one of them is missing on the front (though you have to be really focusing on it to notice). Still fabulous, probably one-of-a-kind eye glasses!
