Cats’ Night Vision Is Very Strong
Cats can easily distinguish colors like green, blue and red. However, the actual superiority of their eyes is that they are created for night vision. Cats’ eyelids open up at nights; so in environments of low light, the colored layer of the eye called the iris makes the pupil larger (covering more than almost 90% of the eye) and allows more light to come in. In environments with high levels of light, this system works in the opposite way to protect the retina, the pupil narrows and turns into a thin line.
There is a layer that does not exist in humans. This layer just behind the retiana reflects the light. Since the light that falls on this layer is reflected back, light passes two times through the retina. Therefore, cats can easily see in low light, and even in dark environments the human eye cannot see in. The reason that cats’ eyes shine under light in the dark is this layer. This layer is made up of tapetum lucidum crystals that reflect light. Thanks to these crystals, the light that falls on the back of the eye is reflected back to the retina. Some of the reflected light turns back from the lens, and causes the eyes to shine at night. Thanks to this structure, the amount of light the eye can see in the dark is increased, and more precisely, available light is better used. Therefore, cats have better vision in the dark. This is not a form of bio-luminescence, because the light is not produced by the animal, but is a result of light being reflected back.
Another reason that cats can see well in the dark is that there are more rod cells than cone cells in their retinas. As it is known, rod cells are sensitive to light only. They form a black or white image depending on the light that comes from objects, but they are sensitive enough to work even with little light.
Thanks to these special rod cells, all cats can easily hunt at night. As it is seen, Allah created the most appropriate eye structure for their living conditions and nutritional needs. Cats’ eyes have markedly different structures and characteristics in line with their own needs. This is one of the unique examples of Allah’s art of creation. Our Lord’s unique science of creation is revealed in one verse as such:
