This diagram highlights critical distinctions: humans have round pupils and double eyelids, while cats feature slit-shaped pupils, a third eyelid (nictitating membrane), and vertically elongated irises for superior night vision. The illustration also contrasts corneal curvature and scleral exposure to emphasize functional adaptations. Each element is labeled for educational clarity.

Used on veterinary, biology, or pet care websites to explain ocular anatomy; supports user intent to understand why cats see differently than humans, especially in low light or motion detection.
