Prada glasses are designer eyeglasses which are much expensive in the local store. However,they are much cheaper if you get them from online optical stores. I love prada purple glasses frames, too. And I try to search them online and finally I find that they usually cost over $100. Most of them cost between $150 and $200. Now I am planning to get a pair of prada purple glasses online. Hope this helps.
I don't know, I never buy prada eyeglasses frames, they are too expensive. But i sister told me last week that she find a good site to buy brands eyeglasses. Framesdirect.com where provide brands eyeglasses frames in low prices. I just search prada purple glasses frames at Framesdirect.com for you. They sell it at $163.30. It is cheaper than in prada shop. You can have a look.
