Can We See A Single Photon Of Light?

Photons are the fundamental units of light that humans directly perceive with their eyes. When we look at an object, such as a chair, we are actually seeing the photons that have reflected off it. These photons form a pattern that our brain interprets as the chair's image. But Can We See A Single Photon Of Light?

While our eyes can detect a bunch of photons, they cannot perceive a single, isolated photon on its own. Each rod cell in our eyes can detect a single photon, but our brain requires the simultaneous detection of multiple photons in neighboring rod cells to process the visual signal.

Therefore, although our eyes have the capability to detect a single photon, our brain does not perceive it individually. If it could, a single photon would simply appear as a brief flash of brightness at a specific point.

fun fact, light and objects have no intrinsic colour, colour only exists in the brain.

the brain is capable thats why it has an error-correction procesa to avoid overatimulation. if it was not capable it would have the self correction, to excite only when it gets multiple signals and avoid stray noise

One time when I was a kid I pushed on my eye really hard by accident while it was almost shut with minimal light. Everything turned green which was cool so I left it like that for a bit and I saw a reflection of my eyelash smack a yellow circle. Maybe it was dust or was it a photon? Still don't know to this day.

They don't see these photons coming

Highly experienced meditators can alter their brains to see a single photon

🤯 got trying to see a chair in the dark lol

Photons carry data... they must.. how absurdly strange.

When I was in bed at night with the lights off and no other lightsource is there besides my phone that I’ve reduced the brightness and the white point of under the blankets, I saw some squiggly lights emanating from my phone screen, are these photons ?

I'm here because I pointed a laser pointer at my hand and looked at it really close. A bunch of super fast red particle looking things were bouncing off my hand. The laser seemed to be spraying them all into one direct point.

It's not a big
It's a feature

[itsszztime]

Ok so.. How can you see photons if their massless? And why do our eyes burn from looking at sun if photons are massless?

[lukakrajina]

Ur wrong actually.. but believe what U want idc
