The nictitating membrane of a masked lapwing as it closes over the left eye, originating from the medial canthus. The nictitating membrane (from Latin nictare, to blink) is a transparent or translucent third eyelid present in some animals that can be drawn across the eye from the medial canthus to protect and moisten it while maintaining vision.
There are approximately forty Krause glands in the region of the upper eyelid, and around 6 to 8 in the region of the lower lid. [2] The function of these glands are to produce tears which are secreted onto the surface of the conjunctiva. There are rare instances of tumors associated with Krause's glands.
Meibomian glands in the lower eyelid imaged under amber light to show vasculature support and the gland structure. Dysfunctional meibomian glands often cause dry eyes, one of the more common eye conditions. They may also contribute to blepharitis.
During their visits, researchers found six geckos with yellow eyelids, the study said. At first, they thought the lizards were a new population of a known species, but when they took a closer look ...

[3] However, variation occurs in the nature of this feature and the possession of "partial epicanthic folds" or "slight epicanthic folds" is noted in the relevant literature.
