This has nothing to do with blind spot. The blind spot is only a thing if you close one eye. Furthermore you only have one blind spot so it would only hide one dot and it would only work at a certain distance from your eye to the screen.
The real reason here is just that the dots blend in with the grey lines when you don’t focus on them.
Your eyes are very low resolution outside of the center of your vision, so your brain makes up a lot of missing info to prevent you from noticing. Try reading this comment without moving your eyes, for example. Keep them straight ahead. It is impossible.
Yeah this, most of the sides of the retinas are meant for color distinction and not granular details, the only detailed part of our eyes is very close to center
So is this like a type of buffering? Saving brain RAM?
Brain interpolating the parts of the image missing due to blood vessels, etc over the retina I think

It’s more like shortcutting via pattern recognition

I think you actually can see them all at once but they just blend in with the grey lines. If the dots were orange, you’d see all of them at once.
