god lmao

i'm sure he's gonna be riding that high forever

hahaha oh no, I'm sure valuable lessons were learned here that will be applied to the next Engineering Stunt

Champion tbqh

oh no :D the worst case

has he published a tutorial yet?

that's hilarious, engineers are great

absolutely peak mad scientist shit, congrats to him, my condolences

yeah

Dudes rock

hahaha, goals.

He's about to become insufferable

Optics was basically the only thing I could do back-of-the-napkin in engineering school.

I'm sorry, this is so devastating for you

Lmao I mean yeah, optometrists have screwed up my prescription multiple times, so I guess I'd kinda trust my own readouts more tbh

that would give me a dangerous amount of confidence if I managed it. best of luck

Cliff, as someone with engineer family: I'm so sorry he was right, good luck.

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.

That's so incredibly metal

ENGINEERS FOR CHRIST SAKE

to be fair diopters aren't the hardest thing
