That said, for normal eyeglasses, there are many sites that offer eyeglasses without proof of prescription. I've been buying eyeglasses from Zenni Optical for almost a decade for my whole family. Most recently in 2021. I have never once even been asked for proof of prescription, I just punch in my numbers and hit order.

One province de-regulated dispensing of corrective lenses and anyone could get in the game, and many did!
