You blink about 6.5 million times a year. While a little blinking can look cute and too much blinking looks ridiculous there is more to it.

• It varies but most adults blink once every 5 seconds. Infants on the other hand only blink once every minute.
• When we concentrate or are taking in important information we blink less.
• There are 20-30 sebaceous glands around our eyelids. They produce oil. When you blink you automatically coat your eye with this oil to help lubricate it and prevent it from drying out.
• You also keep your eyes from drying out by coating them with tear fluid from the tear ducts each time you blink.
• The oil and tear fluid help flush dust, dirt and other things from your eye.
• Blinking is also a way of shielding your eyes so things don’t get in them. This is why you naturally blink when you’re startled or when something moves quickly toward your face.
