Light, or the lack of it, affects our vision, but how exactly do dogs sense and navigate in the dark? Let's take a look at this unique ability of dogs and reveal the secrets of their night vision.
Let's start with the fact that dogs have twice as many rods (photosensitive cells) in the retina of their eye than humans. This allows them to more easily distinguish light in low-light conditions. In addition to rods, dogs have special cells known as rods that allow them to absorb more light.
This ability, known as photophoresis, allows them to see in the dark much better than many other animals. The large volume of retina in their eyes also provides a larger surface area to absorb light, improving their ability to see in low light conditions.
It is important to note that, compared to humans, dogs are more prone to side vision and less capable of distinguishing colors. They are more focused on detecting movement and shapes rather than colors, which makes their vision less sensitive to different hues.
In some cases, dogs can be sensitive to infrared radiation, making them effective at finding heat trails in the dark.
Dogs have great abilities in understanding space and detecting various objects, even in low light.
Dogs' dark vision is an amazing adaptation that allows them to function and navigate in a variety of lighting conditions. Understanding these characteristics can help you better understand your four-legged friend and create a comfortable environment for him, especially at night.
