Why? You know reasons?

    Peripheral vision is weak in humans, especially at distinguishing detail, color, and shape. This is because the density of receptor and ganglion cells in the retina is greater at the center and lowest at the edges, and, moreover, the representation in the visual cortex is much smaller than that of the fovea[1] (see visual system for an explanation of these concepts).

    It took me a while to see ONE dot.

    I can only see 2 at a time. The rest just disappear

    @electrineer hmmm I can too if I move my phone far enough from my face. Part of it could be screen size

    @theabbie not really, you should be able to see all dots if you looked with both eyes, because the blind spots would land on different places.

    @electrineer Yeah, a similar illusion had blind spot thing, so, I thought so,

    How can we prove that it's even up to 12 dots 🤔?
    And also if we were able to see all dots don't you think that will come at a cost on our ability to focus quickly at a single item without the brain blurring out the surrounding image?

    Oh okay. I had to cover all others to see each individual dot. Thought my eyes and op was playing a quick one.

    Here, I fixed it

    I guess, that because peripheral resolution is pretty low and humans have integrated noise reduction, the high contrast parts just get low-passed away where imaging resolution is too low.

    Wait, you guys see dots?

    As people have already mentioned, our peripheral vision is weak. The brain fills in alot of the details where it’s not clearly defined, and since most of the grid is dot free I guess the brain assumes everything in the peripheral view is.

    Focus the top left corner. Then move the focus slowly. Try to move your gaze slowly.

    Held my hand over 2 3rds of the image. Then saw where the 3 dots were vertically. Once you know where the dots are, I think the brain adjusts to keep assuming the correct pattern and I seem to be able to see a lot more and not have the "popping in" anymore.

    Yeah, because the stupid watermark is in the way.
