In brief: Lubrication

Blinking serves at least two functions: removing debris from the eye surface, and lubricating the eye.
Eyelids act as "reverse windshield wipers" - they push tears onto the eye's surface in order to keep it moist and nourished. Blinking can clear up vision temporarily in those whose eyes have become dry (from excess staring at the computer, for example), but does not relieve strain.
