1. Structure:
* Pupil shape: Komodo dragons have vertical pupils, similar to cats and snakes. This helps them see better in low light conditions. Human pupils are round.
* Lens: Komodo dragon lenses are more spherical than human lenses, allowing them to focus on objects closer than humans can.
* Eyelids: Komodo dragons have a transparent third eyelid called a nictitating membrane, which protects their eyes while still allowing them to see. Humans lack this structure.
* Color vision: Komodo dragons are dichromats, meaning they can see two primary colors (possibly blue and green). Humans are trichromats and can see three primary colors (red, green, and blue).
2. Function:
* Night vision: While not as good as some nocturnal animals, Komodo dragons have better night vision than humans due to their vertical pupils.
* Heat sensing: Komodo dragons have a pit organ near their eyes that senses infrared radiation, allowing them to "see" heat. This helps them hunt prey, even in low-light conditions. Humans lack this ability.
* Depth perception: Komodo dragons have good depth perception, which is essential for hunting and navigating their environment. Humans also have good depth perception, but it is achieved through slightly different mechanisms.
3. Eye size and placement:
* Size: Komodo dragon eyes are relatively small compared to their body size.
* Placement: Komodo dragon eyes are positioned on the sides of their head, giving them a wider field of vision. This is beneficial for hunting and detecting predators. Human eyes are positioned on the front of our heads, providing better depth perception and binocular vision.
In summary, Komodo dragon eyes have adapted to their specific needs, allowing them to excel in hunting and navigating their environment. These adaptations result in significant differences in structure and function compared to human eyes.
