      I don’t understand why this still happens. How have car manufacturers still not realized that they need to polarize their displays in the opposite direction? Tons of people wear polarized lenses, especially for driving! It’s not even a niche use-case, like half the options my optometrist offers are polarized, they’re everywhere. And the fix is so incredibly simple - just rotate some of your manufacturing equipment 90 degrees. Boom, done, problem solved.

      This has been quietly driving me crazy for years.

        I would simply prefer my car didn’t have any screens at all. If a new car just powered off the screen while not using the backup camera it’d have my attention so fast.

        From a technical standpoint it doesn’t matter which way something gets polarised. Trouble is that some manufacturers do it one way and others the other way. Which means that it’s not standardized. Having it be mandatory to do it one way and one way only for a given product would solve that issue because then it would be correct every time. Barring the one or other Monday where someone for some reason messes it up before noticing.

          Yeah, it’s bizarre that this isn’t something that’s been standardized yet. Things you look into should be polarized one way, and things you look out through should be polarized the other way.

          If the EU can sort out USB-C, maybe they can fix this mess, too.

          Instead of trying to standardize screens, standardize the glasses lens at 45°. Now every screen is half as bright but no screen is black. Assuming the manufacturers of the screens dont also decide to rotate their polarization to 45°

      You know that you can just buy a sheet of the right filter and tape it over the display? There are probably even specifically designed screen protectors with this.

        It’s the same filter, just turned 90 degrees. You’d need to peel off the old filter if it’s even removable, and replace it with a new one.

      I just watched this movie for the first time last week. It is cheesy as heck and the story isn’t deep (I know it is an action movie with a bit of story thrown in there). Nonetheless I was so impressed by the beginning of the movie that it made me ponder a lot on my own when the movie ended, even though those views already permeated my mind. I would recommend this over Robocop which is what people throw around for the same “vibe” (action with some deep lore).
      Edit: Mid 90’s kid btw!

    That’s a pretty sweet perk. How did you get this achievement? Did you have to throw like a thousand ads in the shredder or something?

    Sometimes I’ll go into a restaurant or a fast food place and they have TVs rotated 90° with the menu shown on them and they look like they’re all turned off until I tilt my head.

    I was parked at a gas station with my car facing nose to nose with another car. I was startled when I put my polarized sunglasses on and saw the person in the other car looking at me while eating a burger. I couldn’t see them without sunglasses because of the glare on their windshield.

    Does anyone else get migraines triggered by polarization? I can’t wear polarized sunglasses at all.

      That sounds strange, because they just filter out and don’t add anything. What does give me headache though are glasses that are too small for me. Maybe your glasses are just a bit too small and the increased pressure triggers the migraine?

        Nah, I’ve tried on friends polarized sunglasses and goggles and what not. My face is small so it’s not a size issue.

        I had a brain injury as a teenager so I think it might be related to that. I’m also pretty sure I’m autistic so it could be a sensory issue because I remember as a child (pre injury) hating wearing sunglasses (probably because they were polarized). Nowadays I can’t be outside on even a cloudy day without normal sunglasses, and my contacts and prescription glasses are transition lenses because of how sensitive to light my eyes are.

          I can’t say I get migraines, but I do get some dissonance with polarized sunglasses that can sometimes put a little uncertainty in my brain and I suppose hurt my eyes. It’s rare and certainly not debilitating for me because ie exclusively wear polarized. I just wonder if it could be related to your issue with them. When surfaces reflect polarized light, the appearance is not exactly identical between my eyes due to offset viewing angles. The rainbow effect isn’t lined up and the color tends to be shifted. The plastic in decent sunglasses usually isn’t varied too much, but it’s somewhat easy to get a tar patch to look green in one eye and purple in the other. This also happens when looking through my car’s tint at other windshields, but there’s usually motion so the mismatch moves out of sight before setting in.

          Does it hurt to wear them indoors?

            It hurts to wear them anywhere, kinda like trying on a friends prescription glasses and getting an instant headache because you don’t need that prescription.

              That is an interesting example because I would say the pain I rarely get (as described above) does resemble the strain pain I get when I try someone’s glasses. I don’t wear any corrective glasses. How many polarized pairs have you tried? I consider myself very aware of warped lensing effects from various sunglasses and they take a bit of adjustment sometimes. I even noticed wavy warp lines once on a rental and had to do a fair amount of driving with one eye closed or else I’d get motion sickness

                I’ve tried on a variety… I worked in the action sports industry so I’ve had access to high end glasses and goggles for a long time, even top of the line brands and what not. It’s the polarization. I wear goggles all the time and only wear spherical lenses because the flat shaped ones have too much distortion.

                  That sounds like you’ve tested this extensively. Ive never heard of this before. I have no further ideas. I wish you luck in avoiding polarized lenses :(

      I can’t wear them in vehicles because the polarization of the glasses through windshields make me car sick.

      I don’t normally get car sick, so it’s only if I wear polarized lenses. I speculate it’s the light being changed as it goes through the tempered glass.

      They’re ok I guess, not much worse than the analog ones, except for the ones that are way too bright. That should be illegal.

      In Iceland there are some billboards that shine like the sun and if you look at them on a red light you’ll have dangerously strong after image. Needless to say I hate them, they should just use e-ink and lights if they want to automate them.
