You can also do it online with Warby Parker as long as you have a credit card (to hold under your face; not to pay with).

Now that is a clever way of doing it!

do they also need the picture of the backside and home zipcode?

if not, sounds like a startup idea.

The PD also varies a bit from reading glasses to distance glasses. If you are ordering single vision glasses, you might want to collect both numbers.
