What is the difference between eyes and camera

The retina has three types of cones; one is sensitive to the colour red, one is sensitive to the colour blue and the other is sensitive to the colour green. These three cones work together to sense combinations of light waves that help us see millions of other colours and shades. Flitting eyes suggest distress or tension. It can be present at birth or can be developed over time, however it is very rare. Sometimes, people with this condition will notice that the difference in size is only temporary, and they return to their normal sizes again.

Red-green colour blindness is primarily found in men. The genes for the red and green colour receptors are found on the X chromosome, of which men only have one. Women, on the other hand, have two X chromosomes and the stronger of the two is superior. This means that even if one is faulty, a woman will still retain correct vision. Your eyes start to develop just two weeks after conception.

This is one of the reasons why it is so important for a pregnant woman to take care of her own body so that her unborn child can develop properly. At birth, babies can only see in black, white and some shades of gray. This is because certain nerve cells in their retina and brain are not fully developed. However, they develop the ability to see in colour as quickly as a week later. People with blue-eyes share the same ancestor. Originally, all human beings had brown eyes, until a genetic mutation occurred between 6, and 10, years ago.

Every single blue-eyed person shares this very distant relative. Male and female brains process colours slightly differently. Research has shown that men and women see colours slightly differently. It is likely that the male hormone, testosterone, affects the way a male brain processes information taken in by the eye.

However, the difference is only very small. Playing Tetris can treat a lazy-eye. Canadian doctors have found that the puzzle game is effective in training both eyes to work together. In fact, it works better than the conventional eye patch. Photo by Angelos Michalopoulos on Unsplash Your eyes are incredibly complex. Photo by Hichem Dahmani on Unsplash 3.

One similarity between our eyes and a camera is the ability to control the amount of light which passes through the lens. Our eyes utilize the iris, which can relax and flex to control the amount of light. In a camera, the aperture can be adjusted to let in different amounts of light.

A major difference between our eyes and a camera is the lens. There is no way to have the depth in the picture as a photograph is a flat medium. This is mainly achieved by the stereoscopic vision of the eye.

A simple demonstration of this can be trying to bring the forefingers of both hands to meet from the sides. This is much simpler to do with both eyes open than with only one eye or almost impossible with a camera.

While changing the focus the retina and parts of the pupil adjust the size accordingly. However, in a camera the focus is changed by the movement of the lens. Eye has a blind spot which is also known as scotoma, whereas, the cameras do not have any such limitations. The eye can also adapt itself to the dark and within a few seconds one can get start seeing better in the dark.

However, if a camera is not equipped to capture images in the dark it can never get accustomed. The eye is highly sensitive to the dust and foreign particles settling on the outer film. Subjective Versus Objective Imaging When you take a picture with a camera, that is an objective image of a single instant in time, and the entire image shows detail and color.
