Concept in Definition ABC

The word watch is the term we use to refer to eyesight that we humans and animals have, while it is, together with the taste, hearing, smell and touch, of one of the most outstanding sensory dispositions that we humans have and that is precisely what allows us through light to appreciate bodies with our eyes.

Sense of sight that allows people and animals to see bodies through light with their eyes

Once the rays of light reach our eyes, the sense of sight takes care of its interpretation; the process and the effect of being able to see is called sight or vision.

Thanks to the receptor organ of the eye, the impressions of light reach us and these in turn are transmitted to the brain through the optical pathways that are responsible for processing information and materializing it into images.

Without the aforementioned process perception It would be impossible for us to perceive the shape of objects, determine distances, and also detect the colors and movements of things and people.

While all senses they play a very important role, that of sight, which allows us to understand and know the environment that surrounds us.

All the senses are important, but without a doubt sight and hearing are what allow us a contact and a interaction effective with the world around us, and for case any problem related to the correct functioning These undoubtedly complicate the development and activities of the people affected.

Vision-related problems: blindness, astigmatism and myopia

With regard to the sense of sight, the main problem that it can present is the absolute lack of vision, known as blindness, and that is a pathology that cannot be corrected in any way.

The causes are varied: accidents or injuries to the eye, diabetes, glaucoma, and macular degeneration.

Although blindness generates some limitations for the person who suffers it, we must say that there are some elements and tools that assist the blind when it comes to being able lead a fairly normal life, such as a cane that allows them to walk and detect obstacles along the way, a trained assistance dog, the Braille system that allows them to facilitates the reading, among others.

And on the other hand we can talk about other minor problems in relation to the previous one, which involve partial vision due to suffering from some pathology such as myopia or astigmatism.

The first is a defect caused by the inability of the lens (spherical body that is located behind the eye pupil) to focus on objects that are far away, and the second is a visual defect due to abnormal curvatures of the refractive surface of the eye, especially in the cornea, but also in the crystalline lens, and that causes the light rays to not be able to focus clearly on a given point of the retina; Now, we must say that both can be corrected from the use of prescription glasses to improve vision and recover the lost part naturally.

Other uses of the term

Although, the aforementioned reference lines above is the most widespread use that is assigned to the word see, it is possible It should be noted that we also use the term to account for so many other issues and situations in the language colloquial how to be: the perception we get of something, either with the intelligence or with any of the senses; the careful recognition of any issue that is being analyzed; the recognition that a person makes regarding the physical state of another being; the visit that is made to someone; the contemplation of a spectacle; being in a certain state; verify that something or someone is in the place indicated or known to be; anticipate a future event and prevent it; and as a synonym for actions such as: consider, judge, reflect, among others.

Also, there are many popular expressions that contain the word see, such as: Let's see (we use it when we want to ask someone to let us appreciate or recognize something or to express curiosity), until more see (it is used when firing someone who thinks they will see each other again soon), Must see (we use it to indicate surprise and annoyance or to highlight something) and see from (to try to do something),
