According to the British newspaper “Daily Mail”, the new tool was developed by the global site TrustedHousesitters for pets, where Angela Laws, Community Director of TrustedHousesitters said: “The bond we share with our pets is very special, and they really understand how they see the moments and the life we share with them.” It makes this bond stronger.
She added: ‘We created this tool to allow people to learn more about pet vision, from understanding your pet’s favorite color to understanding how they see you, and it can give owners a new understanding of their best friend.’
The new feature allows you to upload or take a photo, then put a filter over it to turn it into what your pet will see. At the back of the human eye are photoreceptors, cells that respond to bright light.
Photoreceptors are divided into two types, one of which is sensitive to movement and night vision, and the other is able to detect color, through three types of cone cells, each of which is more sensitive to a specific color, either red, green or blue.
Dogs have only two types of cells that are sensitive to blue and yellow, which means they can only see these colors as well as shades of grey.
This is similar to approximately 9% of people with red-green color blindness, which makes green appear redder.
However, dogs’ retinas are heavy, which is why they can see better in the dark and can detect movement much better than humans.
Dogs’ eyes are also set at an angle of 20 degrees and are much further from ours, which increases their peripheral vision. This gives them a field of view of 240 degrees, which is greater than 180 degrees for humans, but means that they cannot see things in 3D and have reduced depth perception.
What dogs lack in vision they more than make up for in their other senses, such as their sense of smell, their sense of smell is 10,000 to 100,000 times more acute than ours, so they can still cope quite well if their vision deteriorates.
Cats are also not believed to be able to see the full range of colors that humans can see, as scientists say they mostly only see blue and grey.
To make up for this, it’s vastly superior in motion detection, thanks to its 200-degree field of view and greater degree of peripheral vision.
Cats also have excellent night vision, thanks to the fact that they have up to eight times more photoreceptor cells, which are sensitive to low light levels.
However, cats also can’t see in bright light because they have 10 times fewer cone cells than us, which makes things appear fuzzier.
On the other hand, rabbits have an almost 360-degree field of vision since their eyes are on the side of their heads, but they have a blind spot right in front of them.
So they rely more on their acute sense of smell, but they also use their whiskers and teeth to help ‘see’ what is directly ahead of them. Jumping mammals also have bichromatic vision, limited to green and blue, and can only see in two dimensions at close ranges, but they can see in Dark ones are better than humans because they have more cells.
While birds can see the full range of colors that humans can see, but also some additional colors that are invisible and unimaginable to us, this is because they have four types of cone cells, and their additional type enables them to see wavelengths of light in the ultraviolet range. instead of just seeing it.
Bird species that have eyes on the side of their head have a field of view of about 300 degrees, while those that have them in front, such as owls, have a field of view of about 150 degrees.
Some can also use ‘monocular’ vision which allows them to focus their eyes on different objects at the same time, as opposed to ‘binocular’ vision where they both focus on the same object at once.
