      It depends. They both contract, but if the second pupil is small, it doesn’t matter. I have a small one, and it just causes uveitis every once in a while. I went half my life without even noticing it.

      You can become sensitive to light, and the irritation can slowly cause blindness. That’s pretty much it

      One fun thing: if you ever get uveitis, wearing an eye patch won’t work. Your eye will still try to dilate with your other eye. Also your pupil/s will stretch like in the pictures.

    On a road trip through Ontario one year we met a couple of teenagers at a country gas station near Ottawa with pupils in the shape of a cat … a vertical almond shape. I freaked out when I saw the girl first and jumped back. She was used to the reaction and said she just looked like that and it wasn’t a trick. She then said her brother had the same thing and he came to see us.

    This was about 25 years ago before novelty contact lenses were around … they may have been around but I had never heard of them at the time.

    It’s a weird thing to see just these tiny differences to the human anatomy … it immediately makes you think that something is wrong or not right. It makes you realize just how easily prejudices are born.

    The two people were really nice small town people and we had a good conversation and we even left them a tip before we never saw them again.

    Then again that is the special thing about differences though … I’ve seen so many 'normal looking" people in my life and none of them stand out, but I can still picture these two and I’ll never forget them.

      Fwiw, 25 yrs ago was 1999, and I remember seeing these for sale at my eye doctor even before that. These kids may have been fucking with you…

      Maybe somewhat… It would let more light in, but it wouldn’t be focused correctly.

          It results in decreased function of the iris and pupil, affecting the physical eye and visualization.

          When the iris becomes deformed, it will disarrange the control of light coming in leading to blurred vision and finding it hard to visually focus.

          From what I’m finding it either has no effect or bad effects but never good effects like better night vision so you just got lied to or they said that as a joke and you didn’t get it.

      Yes, sorry. It is a problem that started over the weekend. I thought I had patched it by doubling the server’s RAM and adding a core, but that was not enough. Some process is causing the RAM use to spike and the image backend is crashing because of that.

        Thanks. I noticed and reset the server a few minutes ago.

        Something has been off recently. The CPU is spiking and the RAM gets used up, which crashes the pict-rs container. The pict-rs won’t reconnect until I reset the lemmy Docker container.

        I doubled the RAM and added one core, but that was not enough to stop this problem, which means that whatever is causing these spikes is unconstrained. I need to look more deeply into Docker memory management to see if I can limit RAM usage such that the crash can be avoided while remaining functional.

            Thanks. I have looked into it a bit more and I think that it is the postgres database grabbing all the memory it can. I have set a hard limit for the postgres container. Hopefully this resolves the problem!
