Funky and different than all others, the Guess By Marciano GM136 Tortoise prescription eyeglasses are one pair of frames that will certainly set you apart from the crowd! They have larger, nearly oval lenses that appear to curve off with a new-age cateye style. They come in a classic tortoise shell coloring, and are a vintage and studios style, with a modern twist. Metal cut-out arms extend out, with an elaborate "M" detail along temples for added class and style!
