If you want clip on sunglasses, why not try a pair online? Not all clip on sunglasses are expensive online. I have just saw a pair of pink framed clip on sunglasses at Firmoo.com. They are sold at less than 30 $. It is really cheap that even lower in prices than some prescription glasses. One of my friends tried that glasses. They are made of good quality. So, get a pair of nice clip on sunglasses in a easier way. Just order it from online.
