Compared to humans, deer have terrible eyesight; if they were to take an eye exam, their vision would be 20/100. In other words, a deer can see 20 feet in front of it as if a person with perfect vision could see 100 feet.
Since there is less light during nighttime, deer have a more difficult time seeing in the distance. However, deer possess an advantage over humans in low light conditions as they’re able to absorb more light than we do.
What Colors Can A Deer See?
Deer can see blue and green color wavelengths best, but they have a more difficult time distinguishing between red and orange. To put it simply, deer are red-orange color blind. They have around half as many cones in their eyes as we do, which affects how they see color during the day and at long wavelengths.
What Other Senses Help Deer to See and Forage?
A deer’s keen sense of smell plays a significant role in its defense strategy. They utilize their noses to locate food, detect the presence of other creatures nearby, and warn the others of potential danger.
White-tailed deer snort and pound their hooves to alert others to danger when they are scared. The white undersides of their tails, which serve as distress signs, may also be raised or “flagged” by these creatures.

Final Thoughts
In conclusion, deer have poor eyesight when compared to humans, but they make up for it in other ways. Additionally, they have a unique ability to see certain colors better than humans, such as blue and green, but they have difficulty distinguishing between red and orange. All of these senses help deer to survive in the wild and to forage for food.
