I want to try this just to see what happens, if I will have again the feeling something is more real than reality.
Because optometrists are illegal in my country (here only medics can decide what glasses you can use), currently I don't have stereoscopic vision, although my brain CAN do it, if I had the correct images sent to my eyes somehow. (one of my eyes muscles is slightly shorter than the other side thus the images on that eye are shifted unless I had an optometrist design me glasses with a prism).
So when I watched Avatar, an actually well made 3D movie, it literally felt more real than reality, despite it being obvious fantasy with aliens, floating rocks and all that stuff.
EDIT: for those wondering, I am from Brazil, here medical professionals often sue the shit out of anyone offering any service remotely similar to an optometrist, they are quite aggressive about it, some attempted to make even discussion of the subject illegal. And when I was trying to get the prism and asked around my medics about it, one of them went really ballistic, I honestly thought the guy was going to punch me. I believe the reason for that is that for many medics, designing glasses is their only source of income, a guaranteed one, since here is ALSO illegal to buy glasses without a medic desining them for you first, even if the new glasses are supposed to be identical to the old ones!
- djrogers 5y agoSounds like a great reason to do a little medical tourism once the present situation is under control.
- thegginthesky 5y agoShouldn't an ophthalmologist here in Brazil be able to diagnose you and give you a prescription for corrective lenses, or even perform corrective surgery? I'm asking in case I might need to look for one in the future.
- ZeroClickOk 5y agoI'm from Brazil too, and my eye glasses are recommended by a optometrist. The only way an optometrist to work is being an ophthalmologist with specialization in "optometry". It is a sad reality from our bureaucratic government that don't give us freedom to innovate.
- thegginthesky 5y agoCool, thanks for explaining this for me!
- speeder 5y agoThe profession of optometry came from physics instead of medicine, many of the early ones with physicists specialized in optics that ALSO understood how the eye worked, optics-wise. In places where they are legal they spend their time learning more and more about optics, physics, math and eye anatomy, they don't study diseases, infections and so on. As result you can't rely on one to fix certain stuff where you do need a medic, but if you need fancy lenses, they will calculate them, not just use a number they get from their measurement machine like ophtalmologists do. They also would be helpful to design proper 3D glasses and whatnot, holograms and so on.
- thegginthesky 5y agoGot it, I was a bit confused as I never had heard about the problem you mentioned. Too bad here in Brazil you can't get the specialized care you need for the condition you have. This is a major screw up and inefficiency from this country. Thanks for explaining the concept more in-depth too.
- ethbr0 5y agoCan you import glasses? Or, say, receive a box that someone accidentally dropped a pair of glasses into, along with the item you ordered?
- kikokikokiko 5y agoBrazilian guy here: my girlfriend just bought two pairs of glasses from China, I don't know from which site exactly, but some AliExpress type of site. She paid 5 dollars each, just telling which degrees she needed for each eye. The quality was the same from the 200 dollars pair she bought with a medical note here in Brazil. Unbelievable. Just telling that, if you want it, you can import it through the mail and it will pass through customs without a problem.
- The_rationalist 5y agowould be nice to share the site
- WillPostForFood 5y agoIf you search for "myopia glasses" on Aliexpress you'll find prescription glasses starting as low as $2. I just added a pair to my cart and the total was $3.31 including shipping. :O
- numpad0 5y agoCould be Zenni Optical. Prescription glasses, right as ordered, no questions asked.
- mkl 5y agoI have glasses from Zenni. Very cheap, and well made. My current glasses cost ~10% of what the previous pair cost me in NZ, and the lenses are better quality. The glasses cost less than the optometrist visit, and I bought a second identical pair as a backup.
- Animats 5y agoNot surprising. Something used in some countries is a briefcased-sized glasses making kit. Eyeglass lenses have three parameters - spherical radius, cylindrical radius, and axis of the cylindrical curvature. The trick is that for round lenses, you can use the same lens for all axis angles, which reduces the number of combinations to a set you can carry around. Once the right set of lenses has been decided, a notcher is used to cut a small notch on the side of the round lens so it locks into the frame and can't rotate.
- graup 5y agoWait – I also don't have stereoscopic vision, do you have any details or sources for those magical glasses with prisms?
- speeder 5y agoI first learned about this prism business when I read this article: https://www.newyorker.com/magazine/2006/06/19/stereo-sue https://www.newyorker.com/magazine/2006/06/19/stereo-sue Back then people even were saying it was pseudoscience or a scam, but seemly there is ongoing research that shows that the article wasn't lying.
- sand500 5y agoMaybe this is a way to do so? https://www.eyebuydirect.com/prescription-lens/prism-glasses https://www.eyebuydirect.com/prescription-lens/prism-glasses? Maybe it depends on the exact condition you have. Is it Binocular Vision Dysfunction?
- JonathanFly 5y ago>currently I don't have stereoscopic vision >my brain CAN do it, if I had the correct images sent to my eyes somehow. >when I watched Avatar, an actually well made 3D movie, it literally felt more real than reality Buy an Oculus Quest 2. (Or any VR headset, but that's the best value at the moment.) It sends seperate images to each eye. You should get that same 'more real than reality' feeling. It may even train your eye muscles to see in 3D, I know I've seen some research into that area. (https://www.seevividly.com/ https://www.seevividly.com/ comes up on a Google search, though it seems to be prescription only)
- karolist 5y agoI'm someone with Amblyopia and would love to hear people's experiences using this. Seems like the project made some waves on reddit and kind of died down. I have bought Oculus Quest last year in anticipation of trying this but the pandemic and work pushed it out somewhat. Watching 3D movies in the theaters just gives me a headache but Oculus actually works fine, I've played a few games and it was amazing...
- gradschool 5y agoI have that too. My right eye keeps steady while my left eye floats around at random (or at least that's how the linguistic side of my brain describes it). It would be great if a VR headset could track the left eye position and translate the image accordingly.

- retpirato 5y agoI would've never guessed Brazil (or any country for that matter) would be like that. I guess I can see why if medics depend on that for their income, but I certainly would've never guessed they would act so aggressive about it. It seems like there should be some other way for them to make enough money. There should be somebody who's specialty is optometry. Do you have specialists for other things like a heart doctor, or cancer doctor?
