Reply to comment by DecentChanceOfLousy in The brain can rapidly detect and process fearful faces that are otherwise invisible to the eye. There appears to be a neural pathway for detection of fear, which operates automatically, outside of conscious awareness. by Wagamaga

Seen by the eye but not perceived by your visual cortex.

Eg. A hunter can stand directly in view of an animal it is hunting and sometimes the animal's brain is unable to process what it is looking at and it will not react to the threat that is in plain sight.

So to the prey, the Hunter is "Invisible" according to Science because the visual input isn't being processed and not because the Hunter is Bending light and becoming see-through.

Invisible is the correct scientific term for when you can see something but not process the information.

So yes it is invisible. "Not perceptible by vision"

Your understanding of what that word means scientifically is what is wrong.

Go back to reading comic books and fiction and stop making up incorrect meanings for words.
