Colour Of Squirrel Eyes
Do squirrels have blue eyes? All are the same eastern gray squirrel species (Sciurus carolinensis), with genetic variations that range from pure black to pure white. Although there are true albino squirrels, there are also white squirrels with blue eyes or dark eyes. Squirrels are dichromats, meaning that they are color blind and only able to detect the colors of blue and yellow.
While squirrels tend to gravitate towards yellow shades, research shows that they are attracted to the vibrancy of oranges, reds, and even purples. Melanin is needed for color development but is also an important component for the proper development of components of the eye including the retina. As animals with these traits tend to have poorly developed eyes, albino squirrels have vision problems.

(One reference suggests that albino grey squirrels maintain good vision. The unique color perception of squirrels stems from the specialized photoreceptor cells located in their retinas. Like most mammals, their eyes contain two main types of photoreceptors: rods and cones.
Rods are highly sensitive to light and are responsible for vision in low-light conditions, providing monochrome vision. Squirrel eyes, like all eyes, rely on special proteins called opsins (a protein that forms part of the visual pigment rhodopsin and is released by the action of light) to detect colour. To solve this, red squirrels have developed a yellow and brown pigments in their eyes, you might even call this, built-in sunglasses.

This protects their eyes from the bright UV lights, as well as protection from flash burns doing the winter, also known as welders eyes, white out or snow blindness. Vision Simple observation of squirrels chasing through the tree tops suggests that they are equipped with good eyesight. Morphological examination of the squirrel eye suggests excellent, wide-angle vision with exceptional focussing power across the whole retina.
We humans, by contrast, have a single point on the retina, called the fovea centralis (or simply fovea), where our colour and detail. Are Squirrels Color Blind? Unveiling the Truth About Their Vision Paul West / Pet And Wildlife Care Have you ever pondered what the world looks like through the eyes of a squirrel? It's a question that tickles the curiosity of many nature enthusiasts and animal lovers. As you watch these agile creatures dash across your yard, you might be surprised to learn that their vision is quite.

Squirrels are fascinating creatures, and their ability to see the world is quite different from ours. You might wonder, squirrels can see some colors, but not red and green, as they have dichromatic vision. This means their eyes are equipped to detect primarily blue and yellow hues, which helps them navigate their environments and find food.
This implies that squirrels are sensitive to blue and green wavelengths, but cannot decipher red. More recently, electroretinographic studies suggest that squirrels do possess dichromatic (two-colour) vision, with colour discrepancy similar to a human protanope (i.e. someone who is red-green colour blind).
