10 Interesting Facts About Dogs' Eyesight

Dogs See Fewer Colors 🌈 Dogs have dichromatic vision, meaning they can only see shades of blue and yellow. They have trouble distinguishing between red and green, which appear as shades of gray to them.

Better Night Vision 🌙 Dogs have superior night vision compared to humans. Their eyes contain more rod cells (which help in low-light conditions), enabling them to see better in dim environments.

Wider Field of View 👀 Dogs typically have a wider field of vision than humans—around 250 degrees, compared to our 180 degrees. This helps them detect movement from the side.

Less Detail 🔍 While dogs can see in wide angles, they don’t see fine details as clearly as humans do. Their vision is more blurry, similar to human eyesight when it’s about 20/75.

Superior Motion Detection 🏃‍♂️ Dogs excel at detecting motion, even from a distance. They can spot moving objects much faster and from further away than we can, which is an evolutionary trait.

Third Eyelid (Haw) 👁️ Dogs have a "third eyelid" known as the nictitating membrane, which helps protect their eyes and keep them moist. It can be seen as a thin, translucent layer in the corner of their eyes.

Scent Over Sight 👃 While dogs have great eyesight, they rely more on their sense of smell. Their noses are much more powerful than their eyes, making scent their dominant sense.
