People May Sense Single Photons
People can detect flashes of light as feeble as a single photon, an experiment has demonstrated—a finding that seems to conclude a 70-year quest to test the limits of human vision.

That might explain the occasional very very tiny flashes of light I see
I thought that was blamed on cosmic rays…

maybe
sometimes just a point of while light
sometimes, a point of while light with a little blue ring around it

Always villianising minorities!

That sounds like something physiological.
You’re not an astronaut, are you?
“Astronauts almost always reported that the flashes were white, with one exception in which the astronaut observed “blue with a white cast, like a blue diamond.”“

Has a side note At the optometrist, I did a optical test that flashes a tiny point of light and I had to click when I spotted one, random times, random positions, I scored very high and she give me this surprised look, I did the test again, another impressive score.
I have exceptional hearing as well.

I can concur with that. If that was false then there would not be any such thing as subliminal.
three volunteers sat in total darkness for around 40 minutes, and then stared into an optical system. When they pushed a button they heard two sounds, separated by one second. Sometimes, one of the sounds was accompanied by the emission of a photon. The participants had to say on which occasion they thought they saw a photon, and how confident they were (on a scale of 1 to 3) about their sighting.
In many cases, they got it wrong; this is to be expected, given that more than 90% of photons that enter the front of the eye never even reach a rod cell, because they are absorbed or reflected by other parts of the eye. Still, participants were able to answer correctly more frequently than would be expected if they had guessed at random—and their confidence level was higher when they were right.
Three individuals! Only three individuals. Who designed a major experiment to have only three participants? It’s amazing that a journal as prestigious as Nature accepted it for publication.

it’s not like seeing light. It’s almost a feeling, at the threshold of imaginationI can concur with that. If that was false then there would not be any such thing as subliminal.

It did mention they were hoping for more participants
But Krivitskiy is convinced that the authors’ method is capable of settling the question once and for all, if the experiment is tested on more volunteers.
A better experiment would be to show the volunteers a variable number of photons, say one to ten. Only if the success rate increases monotonically with number of photons can the result be considered as definitive.

I wonder if it would improve if people took a photon pill and crooks began to worry

lol
What if 1 photon can see everything?
