We all blink. Now tell me who does not blink.No part of the body is useless. The average person
blinks s 15-20 times per minute frequently that our eyes are
closed for roughly 10% of our waking hours overall. Blinking is the rapid closing and opening of the eyelid.It is an essential function of the eye that helps spread tears across and remove irritants from the surface of the eyes shielding the eye from foreign bodies.
Blinking provides moisture to the eye by irrigation using tears secreting from the tear duct and a lubricant the eyes secrete. The eyelid provides suction across the eye from the tear duct to the entire eyeball to keep it from drying out.

Each blink is an interval of 2–10 seconds; actual rates vary by
individual averaging around 10 blinks per minute . However, do you ever wonder after reading a book or watching a long movie the eyes gets fatigued ? It is when the eyes are focused on an object for an extended
period of time, such as when reading, the rate of blinking reduces to 3 to 4 times per minute. This is the major reason that eyes dry
out and become fatigued when reading. Blinking is an essential activity. If you notice your rate of blinking is more than what is scientifically approved and you feel uncomfortable, Please visit an Eye Doctor today.
