What Color are Deer Eyes at Night? Unveiling the Mystical Glow

What Color are Deer Eyes at Night

If you have ever been in the woods at night or driven along a dark country road, you may have come across a deer with its eyes shining brightly in the darkness. Have you ever wondered what color those eyes are? In this article, we will explore the mystery of what color deer eyes are at night.

Understanding Deer Vision

Deer have a type of vision called “tetrachromatic vision,” which means they have four types of color-sensing cones in their eyes. While humans and most other mammals only have three types of cones, this extra cone allows deer to see a broader range of colors.

However, when it comes to night vision, deer are better adapted to see in low light conditions than humans. This is due to a few factors, including the structure of their eyes and the presence of a reflective layer called the “tapetum lucidum.”

The Tapetum Lucidum

The tapetum lucidum is an important component of a deer’s eye that helps improve its night vision. This layer sits behind the retina and reflects light back through the eye. It is this reflective layer that causes a deer’s eyes to shine brightly when exposed to light at night.

The tapetum lucidum also enhances a deer’s ability to detect movement in low light conditions. It amplifies any available light and improves the overall sensitivity of their eyes. This feature is especially beneficial for deer as they navigate through dimly lit environments to find food and avoid predators.

Deer Eye Color

Now, coming to the color of a deer’s eyes at night. Contrary to popular belief, deer eyes do not emit light like a torch in the darkness. Instead, their eyes appear to shine when light is directed towards them.

The glow you observe is the reflection of light off the tapetum lucidum. This reflection causes a characteristic “eyeshine” effect, making the eyes appear bright and different from their actual color.

During the day, a deer’s eyes typically have a brownish or amber color, but at night, their eyes may reflect shades of green, yellow, or even red. The color of the eyeshine can vary depending on the individual deer and environmental factors.

Why Different Eyeshine Colors?

The variation in eyeshine color is primarily due to the different pigments present in the tapetum lucidum. Similar to how a prism splits white light into different colors, the tapetum lucidum can scatter and reflect light differently, resulting in various eyeshine colors.

The exact color of the eyeshine can also depend on the intensity and angle of the light source. Artificial light sources, such as car headlights, may cause the eyes to reflect more of a white or greenish color. On the other hand, if you were to shine a red light towards a deer’s eyes, you might see a reddish eyeshine.

Frequently Asked Questions Of What Color Are Deer Eyes At Night? Unveiling The Mystical Glow

What Color Are Deer Eyes At Night?

Deer eyes appear to be reflective and glow green when caught in the light at night.

Do Deer Have Night Vision?

Yes, deer have exceptional night vision, thanks to a high number of rod cells in their eyes that enhance their ability to see in low light conditions.

Why Do Deer Eyes Glow In The Dark?

The glowing effect in deer eyes at night is due to a mirror-like layer, called the tapetum lucidum, which reflects light back through their retina, aiding their night vision.

Can Deer See In Complete Darkness?

Although deer have great night vision, they cannot see in complete darkness. They rely on available light or moonlight to navigate their surroundings effectively.


In conclusion, when you spot a deer at night with its eyes shining bright, those eyes are not glowing, but rather reflecting light off the tapetum lucidum. The actual color of a deer’s eyes can be brownish or amber during the day, but at night, they may appear to have different shades of green, yellow, or even red.

While the color of a deer’s eyes at night may vary, it is undeniably fascinating to observe and a unique adaptation that helps them navigate their nocturnal world. So, the next time you come across a deer with shining eyes in the darkness, take a moment to appreciate the wonders of nature’s design.
