RostrioThe eyelids are the folds of skin that protect the eyes from dirt and moisture. Humans have two eyelids, one above and one below the eye, while some animals have three.
Eyelashes are located at the edge of the upper and lower eyelids, which prevent particles from entering the eye by quickly closing the eye upon touch.
Functions of the Eyelids
The eyelids serve multiple functions:
- Protect the Eyes from Dirt and Moisture.
- Close the Eyes During Sleep.
- Moisturize the Eyes by Blinking.
Rules for Eyelids on Passport Photos
The passport photo requirements state that the eyelids must be fully visible in your passport photo.
If your hair falls over your eyes or eyelids, your face may not be recognized, and droopy eyelids can pose a problem in meeting this requirement.
