I'm an Americal living in Portugal where it is very difficult to get information about near/mid-range vision glasses. On the net I've come up with several names: Access, Interview, and Desktop, among others, but no information to help me compare them. Can anyone help?

Visit your local optical shop, that's going to be your best bet. Ordering online has always been really iffy to me, mostly because the person ordering usually isn't someone that is trained to know what the RX means. And sometimes the online places don't even require a prescription.
