WHY WE BILK OUR EYES

We blink our eyes every six seconds. Although blinking eyes ins an involuntary action, we can raise or lower the number of blinks voluntarily. Blinking our eyes automatically supplies two forms of safety to our eyes, to keep them from drying out, and to keep foreign matter from entering and irritating our eyes. The rims of our eyelids are lined with 20-30  oil-producing glands. Blinking automatically coats the eyelid and eyelashes with the lubricant it secretes, to prevent them from drying out.
