The squirrels are unable to be seen through the glass. They aren’t sure what glass is. Since squirrels don’t have the same amount of eyes that human beings, they struggle to discern the same amount of reflections of light. This is what helps humans recognize glass as an obstacle. The squirrels are also color blind, making it more difficult to distinguish between stained or colored glass. Glass that is frosted may also be too opaque to be able to see through for squirrels. They didn’t develop the cones or muscles required to see clearly through the glass.
However, their vision plays a crucially in their existence. Other rodents, like rodents and mice, are night-time creatures in the natural world. Because rats spend the majority of their time in darkness, they tend to be blind and utilize their whiskers to navigate tools. But on the other side, the squirrel is energetic and running throughout the day, relying on their vision to identify predators. The difference in the ability to see rodents and squirrels can be apparent in the fact the brains of visual squirrels are more developed than those of other rodents.
There are two kinds of photoreceptors found in the retina of squirrels: cones and rods. It is possible to view even in low light conditions is made possible through the presence of rods. The density of rods differs among different kinds of squirrels. They have receptors. Ground squirrels have an average rod density of 10%, whereas the grey squirrel has around 40%, and the nocturnal flying squirrel has a rod density close to 100 percent.
So the ability of squirrels to see in the dark differs greatly between the different kinds of squirrels. The albino squirrels are the sole outlier to this rule. Albino animals are unable to produce a crucial pigment known as melanin. Melanin is essential for the development of color but is also an essential ingredient in the proper development of all the parts of the eye like the retina.
