When we close our eyes, in light we can still see shadows and slight movement due to how fine our eyelids are - our eyes perceive the light and any interruptions beyond them slightly.
When we close our eyes in darkness, we have less of this effect as there is less light to see on the "other side". More purely darkness...
Though sometimes in both darkness and light, we see colours too, "washes" of colour, usually (at least in my case) ever changing, ever moving...whether or not these are in the mind or an effect of the eye itself is perhaps something to consider for another question - it is not mine.
For both of these times, light and dark we can also see residual images, particularly when bright light has been involved prior to lights being off and/or eyes being closed.

So what if you are blind...let's go to the extreme of that condition - lets say you have no eyes whatsoever, you were either born without them or they were destroyed/removed in an accident.
Your eyelids are likely permanently closed or there's skin grafted/grown over where they should be, though make no mistake the organs themselves do not exist for you.
What do you "see"?
Black? Nothing at all? Something less than black?
What is your perception so to speak?
I find it hard to believe it would just be the same minus the colours/residual images, even the darkness, all those layers of black, are they not visual in some way? Though I cannot imagine any less, or what would be there in its place?
