okay so my partner was having vision problems

and instead of going to an optometrist he made up a bunch of calibrated charts to measure his own prescription (which is not a simple one) like "no, I'm an engineer, I know optics, I can figure this out" and just ordered direct from Zennioptical and went around for like a year with these self-calculated glasses while I kept saying will you please go to someone who actually has a degree in this stuff instead of doing this extremely engineer thing

and today he finally went to a real optometrist

who said that he got the prescription right

Works really well for something as simple as measuring how nearsighted you are in diopters. That one number that optometrists tell you, which tell you how 'blind' you are is really just a measurement of 1 divided by how many centimetres you can see clearly before there is blur. Which is something you can do easily enough at home. There are websites online that show you stuff like spinning graphs that calculate your precise visual acuity based on if you can determine which direction they are spinning. For someone not interested in all that math you could also just slowly walk towards a Snellen chart until all the lines are fully readable without any blur. But blur can be very hard to recognise so it's pretty subjective.

The hard part is if you have any astigmatism at all. Astigmatism is directional blur and it's a whole lot messier mathematically. That's why they typically use big machines that show you an image and stare at your eye to calculate your astigmatism. The only real value of an optometrist to someone like your partner is testing astigmatism and general eye health.

Best of both worlds is to just go to an optometrist to check your eye health, get your astigmatism and general blur measurements, and then say thanks and order glasses online. Luxottica holds a monopoly over pretty much every single pair of glasses on display at your optometrist, which is why your $20 pair of glasses is being sold as $200.
