Best Answer

The human eyes contains liquid that protects it from ultraviolet and infrared rays as well as particles that may enter it.

The blinking allows for the spreading of this liquid so that the eyes do not dry out.

At the same time, it may allow for disposal of particles that may have entered the eye.
