can dogs see in the dark ? Or can dogs see you better in total darkness? Or he can’t see you at all.
When you turn off your room lights and go to bed at night, The glow of the moonlight Or the bedside clock light allows creating some shadows We may not be able to see the features of the place, but what about dogs?
can dogs see in the dark ?
Many dog owners ask this question, Wondering how their dogs eyes work. And how they perceive things around them ..
However, we must be careful when assuming what animals actually see, Because we don’t know what her brain interprets from the information she receives.
Anatomically and functionally the eyes of dogs are very similar to ours, They can see in the dark like what we can do. Dogs have cornea, The focus of the lens, the retina of the eye, and cone cells into the dog.
Also place the eyes on the front of the head, A sign that the dog is a predator and not a prey, Prey has eyes on both sides of its head “Like mice and rodents” But dogs have eyes in front of the head, Makes dogs limited peripheral vision Like humans and a good deep look.
Also, the eyes of dogs work and functional, such as human eyes. Light enters through the cornea and then the focus, Where it expands and convex to control the amount of internal light, Then light passes through the lens and hits the retina, and there the light is processed.
What is the difference between the eyes of dogs and human eyes?
The main difference between the dogs eyes and the human eyes, In night vision capabilities are located in the retina.
The retina consists of bacillary cells and conical cells that interpret light information. Bacillus deals with low-light visibility while cones process bright light and see colors.
who can see in the dark better ?
Dogs have a better view in the dark because Bacillus cells are dominant on the retina of the eye, Whereas the human retina has more conical cells.
In addition, the retina of the eyes of dogs has a lot of bacilli, Dealing with low light, They contain a reflective tissue below the retina, Called (tapetum lucidum), This fabric is said to help them use less light more efficiently.
Scientists also speculate that dogs do not see in the dark completely, But they see much better in low light or dim light, More than we can because of these differences.
Can dogs distinguish between colors an can dogs see in the dark?
Scientists say that since dogs have more bacillary cells and fewer cone cells, They have the vision of a limited color. The human eyes they have to see the tri-color.
Meaning they have three different types of conical cells that absorb different wavelengths of light, This allows most humans to see colors from the red to violet spectrum.
Dogs are on the contrary, As it is a bilateral vision (dichromatic), It has two types of conical cells. Dogs are likely to see blue and purple colors, But the colors between them (such as: green, yellow, red) They may blend with each other and appear the same color.
So scientists say dogs have what is called color blindness. Where they have limited color vision may be like some people infected with color blindness, They essentially lack the ability to distinguish between colors such as green and red.
Summary of speech,
That dogs see in the dark better than humans, But they don’t have a complete vision of colors like humans, In addition, they rely on other senses such as the sense of smell and hearing mainly.
