Why not match your kids in primary school with these awesome glasses in primary colors? This full-rim, small, plastic Kids’ eyeglasses frame comes in bright blue or yellow, two of the three primary colors. The temple arms are embedded with stainless steel rods to make them easy to adjust. When you show your boy or girl these glasses, tell them these are primary colors, and there’s one more. If they know the third is red, they can move up to secondary school – in colors, at least.
