Parts of the Eyelid: Understanding Their Structure and Function
Learning about the parts of the eyelid helps you understand how these delicate structures protect and support your eyes. Each eyelid is made up of several essential components — including the skin, muscles (like the orbicularis oculi), tarsal plates, conjunctiva, and fat pads — all working together to ensure smooth movement and proper eye function. The upper eyelid also features lifting muscles such as the levator palpebrae superioris and Müller’s muscle. Knowing the anatomy and parts of the eyelid is key to understanding common conditions like ptosis, droopy lids, or eyelid swelling.
