Help in ordering bargain glasses?

Help in ordering bargain glasses?

I have ordered from 39dollarglasses.com in the past and I have been very pleased with the result. So this evening I took the prescription and went to order only to find that I can't understand the notation for sphere or cyl. (To me it looks like "+02r" and "-17r" but I have no idea what this means.) Anyone experienced with eye prescriptions think they can help? If nothing else I can wait and call the Dr. on Tues but I was hoping someone could just explain this quickly.
