Mars is 1.52 AU from the sun, or 1.52x further than Earth, so the inverse square law says 43% less sun power. But the atmosphere is thinner and a different composition.
To know how the human eye actually operates on Mars, one would have to get a human eye to Mars.
Red rover, red rover, send a human eye over.
And, that eye would still need to be attached to a human. A living one. No shortcuts just launching the eye in a jar ;)
Oh, man, you should have said something an hour ago. Now what am I going to do with these jars?
And the other eye…
What if we connect that eye to a neurolink?
It will quickly become festered with ads about where to buy a Cybertruck.
Time delay would be super disorienting to livestream it into your ocular nerve or something... But sure!
I wonder if a human could even properly make sense of the difference after spending so long on a ship between the planets. Plenty of time to adjust
This is more in line with what I was asking. The sun seems to have a psychological impact on humans. I wonder what that impact would be under both relentless cold conditions, but also when the sun never quite feels the same.
I mean, it is obviously subjective and not critical to the functioning of life or anything like that, but it just seems like one of those very subtle "death by a thousand cuts" kinds of elements that might become noticeable over time.
I don't think anyone would directly perceive the effects in a binary logic kind of way. It would be like times when our local region is covered in thin high atmospheric clouds for weeks on end. It becomes more noticeable over time that this amount of light is not normal. I wonder about that awareness of "this is not normal" having more long term impact on psychology, not profound impacts, just some impact. I thought maybe someone had already posted images somewhere on the interwebs exploring this, but haven't found any.
Depends entirely on the ship's lighting.
I guess I meant more about how well you'd actually remember the brightness on earth after being on route so long rather than your eyes physically adjusting
