    This is one of many reasons the perfect eye argument by creationists is utter bullshit.

    • themeatbridge@lemmy.world ⁨1⁩ ⁨day⁩ ago

      Ugh that drives me crazy. The human eye is a perfect example of observable evolution. Organisms exist with every stage of eye development, from a photosensitive spot to a more advanced convergent evolution of our eye. And the human eye is poorly designed for it’s current use, resulting in a significant percentage of people requiring corrective lenses.

        It’s a good example of evolving towards a local maximum then being unable to travel through a valley to a more optimal design. As such it confirms exactly what evolutionary theory would predict, and not what “intelligent design by an omniscient creator” would predict.

        most of the dipshit “the eye is to perfect to have evolved” people also have cheap optics on their rifles. something to think about

        In the lore of Lord of the Rings, it is said that the supreme being of that universe personally created both men and elves and since men were his favorite creations, he gave them the gift of… having pretty short lives (wow, thanks). Well, octopuses have a much shorter lifespan than us, so if our universe’s creator is anything like the Middle Earth’s then there’s a good chance they are his favorites.

      As usual with biologists, if they don’t understand what it does they claim it’s a useless byproduct of evolution. A few years later they discover there is actual purpose to it and it’s actually pretty nifty. Rinse and repeat.

    Because of this we have blind spots, one for each eye. They are not usually noticeable because 1) the blind spot of one eye can be seen by the other, and 2) the brain fills in the gap.

    So with this I will perform a magic trick, I will make your thumb disappear: Close your left eye and with your right look at a spot in the background, make a thumbs up gesture and place the tip of your thumb on that spot, move your thumb to the the right continuing to look at the spot in the background, when your thumb moves about 15 cm your thumb should disappear.

    You can use you left eye too, just switch the directions.

    source
    • Carrot@lemmy.today ⁨7⁩ ⁨hours⁩ ago

      Woah, i didn’t know that the effect would be so drastic. I want to point out to those struggling to get it to work that, as diverging mentioned, your arm needs to be fully extended. Also, the blind spot is about a thumb’s width, at least for me, and is only visible at a specific x/y axis location. Any deviation from that single spot will cause it to stop working. I could tell I was close to the spot when parts of my thumb would disappear, and just had to slowly move it around until I found the spot that looked like the thumb was gone completely.

      It’s way too late at night for all those directions, somehow ended up creating my own blind spot by sticking my thumb in my bum.

      source
      • diverging@piefed.social ⁨1⁩ ⁨day⁩ ago

        Well, I guess your thumb disappeared.

        I can try another way the blind spot is about 15 cm at arms length to the right of the right eyes center of vision. So put your thumb there and it should disappear

      It looks like there’s just a gap in spacetime or something.

      By the way, your eyes are not meant to track your thumb when doing this, you have to keep still and move only your thumb for it to work, so don’t move your eyes.

      source
    • drmoose@lemmy.world ⁨21⁩ ⁨hours⁩ ago

      the brain fills in the gap

      To expand on this, current leading theory (predictive processing) says that brain first generates a visual image than confirms it with inputs and if there’s no input to confirm/deny the halucination it’s just accepted as is. So we can have a whole load of blind spots in all of our sensors and continue functioning rather well with an ocassional artifact.

      • Whats_your_reasoning@lemmy.world ⁨13⁩ ⁨hours⁩ ago

        I think about this at night when my eyes are forced to attempt to make sense of the low light levels in a dark room. I know my room isn’t grainy and grey-scale - that’s just the best my eyes and brain can do at night. It’s interesting to look around and try to imagine the proper colors and shapes of things, reckoning the difference between what I know and what I see in the moment.

        With our brains constantly making things up to explain gaps in information, it’s no wonder kids think they see “monsters” in the dark. It’s also no wonder that nightlights work well to keep said “monsters” away.

      I couldn’t make it work. But I did notice that the spot in the background changed focus a tiny bit at one point. I suspect my brain was tracking the thumb and simply refused to continue to truely focus on the background spot. I tried and tried, but just couldn’t make it happen. Neither eye. :(

        Make sure to hold it at arm’s length, if you weren’t already. If it’s close to you it’s too big to vanish into the blind spot.

    convergently evolved eyes, cephalod pod eyes evolved very differently from tetrapods. cephalpod eyes evolved by forming an invagination of those tissues. whereas the tetrapods evolved as extensions of thier brain.

        no they’re not. by definition if you don’t have what you need you don’t survive. we definitively don’t need it. or at least haven’t for millions of years. that’s different from saying we wouldn’t benefit from it.

        although that’s not a guarantee either. more information isn’t always better.

    Quick way to find your blindspot:

    1. Close your right eye
    2. Hold your phone/monitor 1ft (30cm) away from your face
    3. Look at the ‘x’ below
    4. Slowly bring your phone towards you (or your face towards the monitor) until the ‘.’ disappears
