Why does closing one eye after the other not feel the same as blinking?
In: Biology
It’s the consciousness of the movement. Even though blinking uses both eyes we do it so often subconsciously that the “action” being taken is essentially letting our eyes do what they do and requires no real concentration other than thinking about it. By comparison closing one eye then the other, regardless of how fast you may be able to do it, requires conscious thought and at least a small degree of concentration to close one lid then the other.
