The surface anatomy of the eyelids includes the upper and lower lids, which protect the eye and maintain the tear film. The upper eyelid is larger, more mobile, and contains the levator palpebrae superioris muscle that lifts it during opening, while the lower eyelid moves less and relies on facial muscles for subtle motion. Both lids contain tarsal plates that provide structure, as well as meibomian glands that secrete oils to prevent tear evaporation. The margins of the lids meet at the medial and lateral canthi, forming the corners of the eye. Their delicate anatomy plays a crucial role in blinking, lubrication, and defense against foreign particles.
