Process of seeing in Human eye
Seeing is a human process that require certain organs playing their role in the eye and to make it an effective process it requires to decide to share information to the brain and that brain interprets and helps understanding after taking the scenes via the process of light for which we will take the process of the same in certain organs to discuss this topic.
To give a basic example, visual tasks are of three types in which near visuals task include reading or writing, medium distance visual tasks include examples like seeing on a blackboard or peeping into any place closely from the outdoor, and the far distance visual tasks include seeing a car coming from far, watching a cricket ball and others;
Thence to have such visual task we require the processing of light and hence let's discuss step by step those organs in our eye that help this process of human seeing below to understand it better-
Roles of outer organs-
Here to begin the process of seeing, light has to be considered in accurate amount and to study the process we should first highlight the outer eye organs with their roles to understand the process basic terms.
To do that effectively we have highlighted them one by one below, so let's explain the process further by mentioning their features to see-
Cornea- This is a smooth layer in the outer part of eye through which light passes and if its surface is not clear, it will not be easy to see as the whole process depends on the same.
Aqueous humur- The role of this humur is to control the pressure constantly so when light passes that pressure helps in letting it through clearly.
Pupil- A round part located in the inner sillary body which helps determine the light to pass without any other challenges and help regulate it's proper movement through. As before it light passes through Sclera and Iris, hence after reaching here its further movement is done for a visual image to form.
Vitreous- After passing through the pupil, the light reaches to the inner jelly shape particle located in the Eyeball which is known as vitreous and here it is further processed to have a clear sight.
Lens- It is a transparent layer in the eye through which light need to pass and depending on the distance of passing light it adjusts the flashes of vision that make it easy for other organs to react.
Thus these are the outer organs by which light first passes and only on that basis the sight can be possible for which we highlighted them first.
Now we shall go on to the inner organs to help the further process of light or visual process to study the term better.
Inner process-
There is also a process that takes place in the further inner Eye body and that also has to be mentioned to understand how the Human eye is able to see with role of them also coming to effect.
To do that effectively we shall again mention the organ particles and describe the structure of light processing in them to make the sight possible, so let's discuss them below one by one-
Choroid- This organ is located between Sclera and Retina where it has the role to transfer the light to retina and from here the process of the inner eye organs comes to effect for helping the sight or visual scenes possible.
Retina- The near layer lining the eye which creates electric impulses helping to send visual messages to the brain.
Macula- the Centre place located in the retina which helps in creating special light reflecting cells responsible to send visual messages to the brain.
Fovea- It is of most importance for light to transfer as cones that are most responsible for visual sight can only respond after the clear light falls on to the fovea being the central place inside retina and hence only in such process the movement of vision can be done easily.
Optic nerve- The main large group of Nerve fiber by which the light transfers to the brain in form of visual message to understand and interpret the things coming into sight through such light being transferred.
Hence from the upper process of the whole eye body mentioned, the light is finally able to pass inside the brain and the images are communicated which ultimately makes the sight of a human eye possible...
Thus on the basis of the facts mentioned above, we can conclude that there is a long process through which humans are able to see and if any of such part gets affected so does the vision. For which we need to realize role of them and via that motive we can close the topic mentioning how that all functioning takes place that helps the process of sight and how effective it is for sure.
