Definition

The eyelids designate the skin plates which are above the eyes. They can be folded so as to close the eyes.

Role

This voluntary act or unconscious when you blink, can protect the eyes from external aggressions. The eyelids are also useful to reduce light, especially for sleeping. They also play an important role in hydrating the cornea, which can clean the eye.
