Ok, this may seem like a very silly question but my mama always said there were no silly questions..... I will leave that at that :) There's a little debate going on here....

So, lets just say hypothetically someone comes into the shop without an Rx but wants a pair of glasses made in a +3.... Can I make it without an Rx? Is that the same thing as giving them a reader off the shelf or does it make it different since I would be grinding the product into a pair of glasses - they don't have a prescription. What about a bifocal with a plano in the distance - those are sold off the shelf as well.....

Thanks
