What is the Difference Between a Sheep eye and Human eye?
🆚 Go to Comparative Table 🆚The main differences between a sheep eye and a human eye include:
- Shape of the retina: A crucial difference between the two is that the sheep's retina is shaped like a rectangle, offering a panoramic field of vision of 320-340 degrees. In contrast, the human eye has a circular retina, providing a narrower field of vision.
- Location of the eye: Sheep eyes are placed sideways on their head, allowing for better peripheral vision. In contrast, human eyes are forward-facing, providing better depth perception.
- Night vision: Sheep eyes have a layer of tissue called the tapetum lucidum behind the retina, which aids in night vision by reflecting light. This feature is lacking in the human eye.
- Number of muscles for eye movement: Humans have six muscles for eye movement, while sheep have only four muscles to move their eyes.
- Color vision: Sheep have limited color vision compared to humans.
Despite these differences, both sheep and human eyes share some similarities, such as having a lens, cornea, iris, and retina.

Comparative Table: a Sheep eye vs Human eye
Here is a table comparing the differences between a sheep eye and a human eye:
Feature | Sheep Eye | Human Eye |
---|---|---|
Pupil Shape | Oval-shaped | Circular-shaped |
Eye Position | Sideways on the head, providing peripheral vision | Forward-facing, giving overlapping vision |
Number of Muscles for Eye Movement | 4 | 6 |
Taectum Lucidum | Present, causing reflection of light | Not present |
Depth Perception | Inferior to humans | Superior to sheep |
Fovea | Not present | Present, with vision cells concentrated |
Color Vision | Lacking | Present |
Sheep have a better peripheral vision than humans due to their sideways-positioned eyes, but they lack color vision and have inferior depth perception. Additionally, sheep have only four muscles for eye movement, while humans have six.
