Eyelids and Eyelashes

The eyelids serve to protect the eye from foreign matter, such as dust, dirt, and other debris, as well as bright light that might damage the eye. When you blink, the eyelids also help spread tears over the surface of your eye, keeping the eye moist and comfortable.
 
The eyelashes help filter out foreign matter, including dust and debris, and prevent it from getting into the eye.
