All people see light when their eyes are open and see darkness when they close their eyes because their eyelids block out the light, why do people see light when their eyes are open and darkness when their eyes are closed?
 
I'm so white that my skin is nearly transparent, and let me tell you my eyelids don't do much against modern light pollution. Need some proper thick curtains on my bedroom.
 
Eyelids are very opaque, when all people close their eyes, they commonly see darkness because their block out light, your skin isn't transparent, though.
 
Other people have the luxury of believing the world can stop existing when they close their eyes. Not me.

I can shine a bright torch through my hand and see my bones. My eyelids present little obstacle to the average light source.
 
Okay, you commonly see darkness like everyone else does, because their eyelids usually block out light, and of course, the world can't stop existing.
 
They don't see darkness, just the absence of light. (Credit to Terry Pratchett)

They do see black but not true black with closed eyes, sometimes they see red when light or sun faces their eyelids.

they are opaque, but far from perfectly so.

close your eyes in a well lit room. there is an obvious difference when you further cover your eyes with your hands vs not. enough that you can tell when someone else holds their hands in front of your closed eyes too, assuming they do so in a way that blocks the light w/o touching you.

eyes are light receptors, you don't "see" darkness, you see light or nothing. as you say, sensory experience does not necessarily align to reality. the world is still there even when your light receptors are not receiving light. and if you take the wrong controlled substances, you might also see things that are not there, brain gets tricked into processing wrong information.

Eyes are light receptors, even if people don't see darkness, they see a dark color which is the absence of light with closed eyes and their eyelids block out light due to them being opaque, some people say they see darkness with closed eyes, but they don't see darkness, they see a dark color which is the absence of light with closed eyes.
 
...but they don't see darkness, they see a dark color which is the absence of light with closed eyes.

A dark color which is the absence of light assumes that light must exist in the space the eyes are currently occupying. If the space the eyes are currently occupying is devoid of light, then by closing the eye will then the dark color which is the absence of light appear a bit brighter then the environment that is devoid of light?

If the answer is no then we need to explain the difference between absence of light being a dark color which would not be the case if the environment surrounding the eye is filled with bright light.

Eyelids are not opaque, they are translucent but with a very small factor of translucence.
 
All people see a dark color with closed eyes, usually black, not but not true black, all people see the absence of light with closed eyes, but not darkness, but a dark color, and who told you that eyelids are translucent? They're opaque, but not 100% opaque.
 
You might want to check what translucent means.
Alright, eyelids are translucent, but all people see a dark color with closed eyes, regardless. People think either eyelids are opaque or translucent, it depends on who you ask.
 
While dreaming, my eyelids are closed, yet I'm registering effects associated with light. We have a dream thread here (welcome on board AmberGirl), and just recently I recounted a dream in which I saw (at first at least) the well lit cockpit of a small aircraft (and later in the dream when it was no longer well lit, it spelled disaster for that plane).
 
If hold a flashlight that has been turned on about one centimeter from my closed eyelid I will see a reddish color that is not too dark but not too bright.

I just tested this in a room that gets lots of natural sunlight. Your statement is not correct. I saw no dark colors.

My statement is correct, All people see a dark color though, they see a blackish color with closed eyes when light is not facing them, I closed my eyes just now and saw a dark color.

You need to be careful with statements using the word "All" or "all" or "ALL". There are normally exceptions to that, and it's not courteous to keep digging when someone tells you their experience is not the same as yours.

People perceive things like colors differently. There is at least one color-blind person who posts in OT, and I have artificial lenses in my eyes. I've encountered people whose "mind's eye" is in black and white, so they don't dream in color and can't imagine things in color (which is very sad in my opinion, but it's how things are for them). It's true that people tend to see darker colors when their eyes are closed, but it depends on what physical environment they're in.
 
People frequently see a dark color with closed eyelids depending on what physical environment they're in when light is not facing them, which is true. There are billions of people in the world that see a dark color with closed eyelids, usually a blackish color but it's not true black. Don't you mean people can't visualize things in color, and I'm not talking about dreams or mental visualization.
