Blink enough to keep away dry eye

Dry eye is a common condition without a cure and if you are one of those suffering from the burning, gritty condition that can impair vision and damage the cornea, check if you are blinking your eyes enough.With computer simulations that map the way tears move across the surface of the eye, researchers discovered that when your eyes are open, the tears get thin right along the edge of the eye.Using the software programme Overture, researchers recre-ated the flow of tears on the surface of an open eye, moving from the upper corner and draining through the ducts at the opposite corner.”One thing we were able to find is that when your eyes are open, the tears get thin right along the edge of the eye, and that is referred to as the ‘black line’,” said Kara Maki, an assis-tant professor at Rochester Institute of Technology in the US.The tears, Maki explained, climb up the eyelid and join a col-umn of fluid that travels along the lids.
