Different animals have different cones. Cones help us see color. For example, a red cone will help us see red and a blue cone will help us see blue.

Humans have 3 cones. Red, blue and yellow.

Other animals can have many other cones, which let them see colors that we can't.

One such example is the mantis shrimp. They have 16 color receptors and 360 degree vision.

Different animals see colors in a different way depending on their eyes.

Us humans see Blue, Red and yellow as colors.

Humans have a binocular vision. Rats have independent visions in their eyes which means each eye looks in a different way.

There are various researches going on to replicate and learn from complex eye structures of various animals and apply them into making advanced lenses cameras.

If all colors of light are reflected by a material, it'll appear white.

Few special animals have night vision because their cells are build differently form other animals.

The light enters trough the cornea and gets refracted into the lens which focuses the light to the retina which has rods and cones which converts the information it gets into electric impulsive and it sends it to the brain using nerves.
There are rods and cones in our retina are receptors that collect light and send the information to the brain.

Cats have a special layer of cells in the back of their eyes called the tapetum lucidum

which gives them night vision

Mantis shrimp have 16 colour receptors

~The refracted rays enter the cornea

~Colors are what is reflected off the surface and whatever color it's not is absorbed and if it's black it generated heat and if it's white it reflects all the colors.

~The wavelength depends on the properties of the object-is it smooth or rough etc.

~Color is an illusion

~VIBGYOR- if an object appears red it absorbs all the colors but red turning it into the object red.

~We can see in the night because of the rods in our eyes

~Cones and Rods react to the light and relay this to the brain using optical nerves.

1) Animals can see some colours which we cannot see

2) Cones are the cells which perceive colours, whereas rods absorb the brightness & motion

3) We have 3 cones, and these enable us to see red, blue and green light.

4) Dogs have 2 cones, they see blue and green as mixed. Also, they have many rods.

5) Cats have excellent night vision because they have cells called tapetum lucidum, which enables them to see at night. Their night vision is much stronger compared to ours.

6) Geckos have only cones and no rods. Their night vision is also much better than ours.

Article:

1) The light waves that enter our eye are refracted in the cornea.

2) The retina transfers the light energy waves to nerve impulses, which is then transferred to the optic nerve.

3) How we can see colour: When a material reflects a light wave of a certain frequency, it absorbs the rest. The reflected light wave is what we perceive as colour (which is actually an illusion).

4) Objects which appear black absorb all colours, whereas  objects which are white reflect all colours.

How do coloured filters work? (Article)

- They allow certain colours to pass through them. the other colours are either absorbed or reflected.

# data[].attributes.body
-Just like how light refracts when it enters different objects and mediums, it also refracts when it enters our eyes.( cornea)
-The light then reaches the retina( located at the back of the eye), which is composed of tiny light sensitive nerves that transfer the energy(through the optic nerve) for the brain to interpret as sight.

-We perceive colour when the remaining light that interacts with an object is reflected back. When an object doesn't absorb all of the light frequency, then the remaining that is reflected will be seen by the observer.

-We have three cones that enable us to perceive the colours red, blue and green light. (rods and cones)

- Animals can see much more than us.
-They don't always have binocular vision as we do, and can rotate their head and eyes 360 degrees( pigeons and rats)
-They had more rods so they can sense motion better.
- Animals like cats have special cells in the back of their eyes called 'Tapetum Lucidum' that allows them to have night vision( 6x stronger then ours )
- Geckos also only have cone cells and vertical pupils that allow them to have good night vision.
-Mantis shrimp's have 16 colour receptors, they see all kinds of light rays in the spectrum such as ultraviolet, infrared, polarised light etc. They are the only creatures that can see circular polarised light. Their eyes also move individually.

There is a significant difference between how we and different animals see the world.

Our sights are based on the amount of cones and rods we have in our eyes. For example, we have three cones which allow us to see red, blue and green.

While we have binocular vision where the view of both our eyes overlap, animals such as the Mantis shrimp don't have binocular vision, consequently they have a different view than us, even if we were staring at the same thing.

Many animals from the animal kingdom have evolved differently when compared to humans. Some have more or less cones and rods. The cats even have a special layer of cells called the 'Tapetum Lucidum' which enables them to visualize better pictures at night than us.

The structure of the pupil also plays a key role in how we see. Gecko's who have vertical pupils can see far better than us at night. Another factor supporting this is the fact that Geckos only have cones and no rods.

The type of eye and the number of colour receptors also can affect which parts of the EMS you can see. The Mantis Shrimp can see many more rays than us such as the UV rays.

Article-

How do we see?

When light rays reflected by other objects reach over eyes, the  white layer on our eyes called the Cornea refracts it leading it inside our eyes where it meets the Convex lens. The convex lens refracts and focuses these rays to one single point inside the Retina. The Retina which has light sensitive nerves create impulses which are carried by the optical nerve to the brain. The brain perceives these impulses and creates a picture which is what we see.

How do we perceive colours?

When the VIBGYOR hit an object, some rays are absorbed and others are reflected depending on their wavelength. The rays which are reflected are the colours we see the object to have. We do not perceive the colour absorbed rays.

When all the rays are absorbed, we see the object to be black. The object also creates heat.

When all the rays are reflected, they continue to form white light and we see these objects as white in colour.

- The colourful part of the eye is the Iris.

- In the middle of the eye, there is a Pupil which is a opening that lets light into the eye.

- The Pupil gets smaller when there is a lot of light.

- The Pupil gets bigger when it's dimmer.

- Blinking protects & moistens the eye.

- The Lens in your eyes focuses the light to the back of the eye and that's the time we can start seeing.

- The Cilliary muscles change the shape of the lens to let the eye change it's focus to something close by & things far away.

- The Cilliary muscles make the lens thicker to see something closer.

- The Cilliary muscles makes the lens thinner to see something further away.

- The Lens focuses the light onto the Retina.

- The Rods and Cones are present in the Retina.
