I'm sure everyone here will agree that you have an extremely easy correction, not strong at all, and contrary to the advice of your optician, you certainly do not need polycarbonate lenses.
In fact, others here will tell you that you should stay away from polycarbonate lenses, and they'll reference abbe values and such - let's just say that the clarity of polycarbonate lenses is the worst of all options you have, with perhaps only stained-glass windows being worse. They will tell you to get CR-39 plastic lenses, which have excellent optical qualities. The small but important exception being that if you want "drill mounted" or so called rimless frames, which cannot be done with CR-39. Spend some time online reading about things like lens materials, it will greatly help you the next time you're speaking with an optician and they're trying to sell you something you don't need. Try the wikipedia site to start: http://en.wikipedia.org/wiki/Corrective_lens - and just google key words like polycarbonate + abbe, CR-39, etc... The more time you invest in researching about eyeglasses, the more likely you will be happy with your online purchase - if for no other reason than your expectations are in line. Good luck, J.
