Blinking is essential for lubricating the eyes. The sebum or natural lubricant, secreted by the sebaceous glands present on the rim of the eyelids, is evenly spread throughout the eyes through blinking. Blinking is a natural mechanism of preventing eye dryness and irritation. However, too much blinking might mean that something is perhaps wrong with your eye or may be you are suffering from an underlying health disorder.
