Which brings up another benefit of using an online eyewear vendor: they let you type your own prescription in. If you are personally fine with using a two-year-old prescription, do it.

When I ordered glasses a year ago, I also played around with the idea of eliminating astigmatism from my prescription by adjusting the cylinder value to 0 (it was only .25 in one eye and .50 in the other) and offsetting the sphere value by half of the difference. Because their buy-one get-one free sale, I got one pair with astigmatism and one without, and got to decide which I liked better.

That's awesome. Anything more than about a half diopter and you'll probably not get away with that in glasses. Contacts can go a little higher. I'm personally astigmatism sensitive, so I have to be spot on for degree and diopter.

To be legally above board, an online provide must attempt to confirm the Rx you enter is correct AND still valid. But few if any do because its a race to the bottom on quality and price. At Topology Eyewear, we spare no expense to ensure you get the best custom frames (like a custom suit) AND the best optics money can buy. We take 100% compensated Rx very seriously!

It depends on the vendor. Warby Parker, for example, requires you to scan/upload the prescription given by your doctor, which obviously has a date on it. I guess it's always possible to just edit out or change the date on it though.
