Mantis Shrimp Eye vs. Human Eye
The Human Eye
There are various parts of the human eye. However, the main parts are the cornea, pupil, iris, lens, retina and optic nerve.
Human Eye
How can we see images?
The eye refracts light into the retina, making the image upside down. However, in the brain, the image is turned right side up. The image is processed by the brain in the occipital lobe. This all happens in an instance.
How We See
Eye diseases you can get
Glaucoma is an example of an eye disease that impacts the human eye. This disease mainly affects the optic nerve. The optic nerve is vital to our vision, for it sends visual images from the retina to the brain. Some symptoms may be severe pain in the eyes and gradual loss of blindness.
Diseases
Mantis Shrimp Eye
Mantis shrimps eye contain 3 pupils in each eye stacked on top of one and another.This creature can see far beyond humans eyes on the light spectrum.The mantis shrimps eyes are also positioned on two supportive stalks.The mantis shrimp also has compound eyes, which are made up of thousands of elements containing preceptor cells, support cells and pigment cells.
Mantis shrimps vision
Mantis Shrimps vision
The Mantis shrimp has 16 preceptors and can see UV and visible and polarized light however despite the mantis shrimps wavelengths it can only discriminate wavelengths less than 25nm apart. Beside the mantis shrimps vision they also have the ability to see in the dark, this is because of their rows they have in each eye. These rows are used to detect certain wavelengths in the dark as well as polarized light. The preceptors cells have played a huge role in the ability to see so well in the dark for these creatures
How does the Mantis shrimp perceive colour
How does the Mantis Shrimp perceive colour
The Mantis shrimp uses a pigment called ospin to help perceive color. The Mantis shrimp has six preceptors while other animals only have one direct relation of ;preceptors to ospin. These preceptors detect light in the ultra violet range which helps the animal recognize colour. However the Mantis shrimp only has two ospins sensitive to ultraviolet light.The Mantis shrimp also has 12 cannals in which they can see colour and that can detect ultra violet, and polarized light that cannot be seen by humans naked eye.
Mantis Shrimp Eye vs. Human Eye;
Different
Compare &
Contrast
As humans and mantis shrimp are very different, so are their eyes. From the structure of the eyes to the way images are seen. The Mantis shrimps eyes have 16 receptors while the human eye only contains 3. Humans are better at distinguishing between colours than the mantis shrimps eyes however the Mantis shrimp can see polarized light, this type of light cannot be sen by the naked eye of humans.
How are their eyes similar
The mantsi shrimps eyes and humans eyes share more differnces than simlarties. This makes sense becuase one lives underwater while one resides on land so they need different eyes according to their surroundings
