i read 700 years of history to fix my glasses

Optician here - this video was fun af to watch and I typed most of this while watching the video, so I apologize if early bits of my comment are addressed later in the video. 1. If your eyelids are touching the lens, we'll add pantoscopic tilt to the frame front. (Bringing the top of the frame front forward, and the bottom closer to the cheeks.) 2. Everyone's bridge (nose) is a different size and tend to do better with either a saddle bridge design if you have a prominent bridge or nose pads (the name of the part you pointed out in red) if you have a flatter bridge. Change of material can increase grip/comfort plus bringing the nose pads inward or outwards can raise or lower the frame front. 3. The history of glasses is absolutely fascinating and I absolutely recommend you do contacts next! 4. You comments on lens fit are about half right. Two important measurements to keep in mind are your A (horizontal measurement) and B (vertical measurement) of the lens. As an optician, I'm going to measure your PD (pupillary distance - which lines up with the A measurement) and your OC (ocular center height which lines up with B measurement). Any deviations from that can induce prism, and greatly effect how your brain perceives the RX. Things might appear taller or shorter for example. (Look up Prentice's Rule if you like math stuff) 5. Lens thickness is not only determined by the strength of the RX, but also the shape of the frame and what measurements are taken and sent to the lab. Generally - if you have a higher RX stick to smaller and slightly rounder frames. Other general fit tips: 1. Temples are adjustable, but it's still important to find a good fit right off the jump. 2. Whatever shape your face is, generally you want to go with the opposite shape for your frame. 3. Understand your Box System! Almost every frame will have something like this this on one of the temples: "52 14 SQUARE 140 ". The 52 in this case is your A measurement, 14 would be your DBL (distance between lenses/bridge), and the 140 is your temple length for that frame. Unlike a pair of jeans where a size 32 is a size 32, these measurements are based off the LENS inside the frame, not the frame itself. I can hand you 14 frames with the exact same measurements and they will all fit slightly differently. 4. That being said - if you know your PD, you can take the A measurement plus the DBL and that equals your frame PD! As long your PD and the frame PD are pretty close, you'll be able to better narrow down a good fit. TLDR; Optical nerd went on rant, am now late for work after ranting. I freaking love my job and will talk to anyone about it as long as they pretend to listen.

Man I always think “they’re gonna run out of questions at some point right?” And then they come up with questions I didn’t know I had and now am too invested in

Potter glasses were a symbol in the uk before potter, they were a symbol of being poor. That style of glasses were the basic FREE NHS glasses. So there was symbolism for potter having those glasses was that the Dursleys wouldn’t pay for Harry’s glasses. Things have changed in the last 30 years so there is a range of free frames available.

My favourite Sabrina quote is now, "So a perk of the pince-nez was that it doesn't PINCE. YOUR. NEZ."

11:20 ''For 700 years, glasses did help people see, but for the first time, they were finally ready to Be Seen.'' Absolutely love that line. <3

when i was a kid my ophthalmologist would study my face for a minute and then show me pairs of glasses that would work with my face shape and then (for certain kinds of frames only, probably) heat the frame to make small adjustments if necessary and i guess i didn't realize she was doing the lord's work

"So i decided to make my own frame" Me: oh cool she's gonna 3d print them? "I'm gonna use this metal wire" Me, who has many hours of experience trying to use metal wire for diy: ......oh god

Every struggle I have ever had with glasses is really summed up in the statement “bro, I just wanna see”

Having grown up as an optometrist"s kid, my first reaction was “just schedule yourself a glasses fitting, girl!!” ...But there's a reason videos of YouTubers doing stuff the hard way are popular: it's a great way to learn things. So thank you for showing your little journey here. You actually taught this optometrist's kid a thing or two. ❤️ I'm going to take some of your advice, because it beats having to schedule a fit adjustment every time I accidentally lean on my frames in bed.

The fact that nose-pinch glasses were literally described as being useful for falling off is hilarious.

3:58 this might be a minor point, but it made me very happy to hear Sabrina phrase testing the hypothesis as “finding evidence to try to disprove them.” That’s a really important point to make about the scientific method that often gets lost in my experience and when learning about how to do research. Research and finding data is meant to be used to try to disprove one’s hypothesis and get closer to the truth, not to just back up one’s hypothesis or beliefs.

OKAY SO. After I got LASIK, my right eye ended up weakening a fair bit, enough that it was kind of annoying while driving. I ended up getting a prescription monocle and I wore the heck out of it. I was surprised how well it stayed in place after I got the fit right. The other nice part is that I have ptosis (droopy eyelid) in my right eye. With the monocle in place, it felt weird for the first month, like I was forcing my eye open further, but just a little. That might have been due to the orbicularis oculi muscle in that eye just being smaller or tighter than my other eye (I could rotate the monocle 180° and fit it in my left eye, which wasn't quite the right fit for lens placement but the monocle frame was essentially the same for this style, which had protruding wire supports extending from the lens frame along the top and bottom of the monocle, to kind of latch onto the flesh over the bones above and below the eye socket). But when I was wearing it, both of my eyes finally looked like they were open the same amount! Plus, all of my patients (I'm a nurse) could just refer to me as "that guy with the monocle."

Melissa getting so caught up in the instructions that she become oblivious to the sponsor segment being filmed to the point of reaching through the shot in front of Sabrina is great. :)

I love how the theories range from "it's years and years of horrible design and beauty standards" to "what if we are just stupid"

Some of the parts where she's just blindly walking to the craft store genuinely look like backrooms footage

I was wearing glasses since I was 11, but almost 4 years ago I made a laser correction and that’s one of the best things I’ve done in my life. It’s just such an amazing feeling to see everything without any glasses or lenses, I can’t even explain how happy I was in the first days after the correction.

The lengths Sabrina goes to answer arbitrary questions never ceases to be appreciated. Also BLUR

A hundred or so years ago in Finland, when the social welfare wasn't on today's level, rich folks would donate their old glasses. They were then put in a box and shipped to poor/rural places where the people in need got to try them and pick a pair that helped the most. I've been told my great-grandmother got glasses this way.

Myopic East-Asian here with some help:  My glasses pushed against my brow and eyelids (they either slid down, bruised my flat nose or did some combination of both) until I got titanium frames. For some reason ultra-light glasses sit right on my face, but don't clamp down. Half the time I forget I'm wearing them because I feel NOTHING. If anyone (especially if flat-nosed) is having problems with the way their glasses fit, I highly recommend getting an ultralight pair. They tend to be slightly more expensive than regular ones, but they're more than worth it. I used to change my glasses every time my prescription changed (as a kid) but these ones have been keepers. P.S: I HAVE heard that "asian fit" nose pads exist… but they're not commonly sold (at least where I'm from) and I'm fine with my current glasses. P.P.S: If you have that problem where you keep seeing over the rim of your glasses, consider round frames. They're great for your peripherals.
