My uncle wants a pair of reading glasses with prism, I wanna buy it for my uncle from the online stores as this kind of RX prescription glasses at the retail stores is much more expensive than the one in the online stores. Could you please recommend any online stores to me to buy the reading glasses with a prism prescription?

I have bought a pair of bifocal eyeglasses with prism for my son from an online optical store PrescriptionGlassesOnline.net, it is much cheaper than the one in the retail stores. You can get on the web site and check with their online customer services about the reading glasses with prism. I think this store will be your good choice!
