ro•sham•bo prescription glasses for adults include your choice of our classic square frame, single vision polycarbonate lenses, carrying case, silicone slip grip ear adjusters, plus free shipping! All ro•sham•bo frames are BPA free, lead & latex free, small parts tested, and available in 5 sizes for the whole family. Our adult size S/M is recommended for teens and more petite adult faces (usually fits women better than men), and our adult L/XL generally fits larger head sizes (or typically men). View our size chart. NOTE: Please make sure to upload your most recent prescription, as well as your pupillary distance (PD) since they are both required to create your perfect pair.
