That is a very interesting observation! When we close both eyes, we perceive a blackness, or perhaps some sort of reddish/purplish glow of light through eyelids, or the after-effect of light. However, by keeping one eye open, it seems any signal from the closed eye is overridden, so you really don't perceive anything there.
- eric_h 12y agoAgreed. Definitely just spent a few minutes contemplating if I was seeing anything through my closed left eye. It seemed as if the only way I could turn my left eye "on" when it was closed was by also closing my right eye.
- heinrich5991 12y agoI can differentiate between light or no light in front of my closed eye, even if the other eye is open. Is this the inverse effect of the effect you're talking about?
