How Does The Human Eye Works?
- Human eye works similar to camera ,each part in the human eye plays in a vital role to provide clear vision. So, we can say that human eye acts as a camera. The eye has a lens, and a sensitive light tissue at the rear of the eye called retina which acts as the photographic film.
How Eye Is Similar To Cameras.
- In camera when we want to see the things clearly we press on zoom ,so that we can make the image bigger or smaller , the same way in human eye happens.
The cornea is a structure found in front of the eye that helps to focus incoming light , we have something behind the cornea called iris, (which is a colored ring shaped membrane) and inside the iris there is a circular opening called the pupil which can stretch or compress depending on the amount of light entering the eye. At the rear of the eye the retina will be found.
- we have many important parts in our eyes supporting role in the main activity of sight such as : muscles that allow eye to move , carry fluid like (tears and blood ) and so on .
- The muscles inside the eyes are important because they are holding lens in their places .when the muscles relax ,they pull on and flatten the lens to allow the eyes to see the far objects , moreover to see the closer objects the muscles must contract .
When Light Passes Though The Eye.
When light enters the eye it will fall on the retina which is light sensitive forming the object image. Certain processes will occur to transform the image to the brain so that we will be able to see objects.
