Vision
Elephant eyes are about 3.8 cm (1.5 in.) in diameter and their vision is moderate. Elephants traverse forests, savannas, and grasslands, primarily orienting with the trunk, as opposed to sight. Ex: There have been documented occurrences of elephant herds being led by a blind member. The complete lack of vision did not hinder the blind member’s ability to fulfill its leadership role.
Elephants have long eyelashes to help avert blowing sand, dirt, and debris from the eyes.
In addition to the upper and lower eyelids, elephants have a “third eyelid” which moves vertically across the eye. These eyelids function to protect the eye when feeding, bathing, and dusting (cooling down). Refer to behavior section.
Some elephants develop a white ring that encircles the iris as they mature. This ring is similar to an age-ring that may develop in humans (as they age) called arcus lipoides, and does not affect vision.
