What Does view Mean
Originating from the Latin term visĭo , the concept of vision allows us to describe the meaning that gives different organisms the possibility of detecting light and recognizing places, people and objects (that is, it enables them to see ). Vision, in itself, is a capacity that animals (including humans) have developed from their ocular structure. In the case of certain machinery or devices that mimic this achievement, we speak of artificial vision .
The visual system sets in motion different mechanisms to make vision possible. In principle, it assumes the task of interpreting the received stimulus to form the corresponding optical image on the retina, through the cornea and lens of each eye. This part of the visual process is in charge of the optical system .
Specifically, we can state that within what is the optical system, we must highlight the fundamental role played by various elements of the eye. These include the cornea, aqueous humor, iris, lens, and, of course, the retina.
Vital part of the eye this last mentioned that can be affected by a series of diseases of more or less importance. Thus, among them we must highlight those known as floating bodies, which are spots in the field of vision, retinal detachment, macular hole or macular degeneration.
On the other hand, the cells that are located in the retina constitute the so-called sensory system of the ocular organ . Here the photoreceptors intervene, which are responsible for capturing the luminosity that reaches them. According to experts, there are two classes of photoreceptors: some that are known as cones and others that are defined as rods.
Other types of cells also participate in this stage of the process, responsible for converting light into electrochemical impulses and conducting them to the optic nerve . Once there, they are transmitted to different areas, among which we can mention the area of the lateral geniculate nucleus and the visual cortex of the brain.
The process of reconstructing distances, recognizing the colors, movements and shapes of objects, finally takes place in the brain .
It should be noted that the dictionary of the Royal Spanish Academy (RAE) attributes many other meanings to the concept of vision, such as describing direct contemplation without any sensitive perception; that of naming an opinion that an individual may have on a specific issue or problem; that of being related to the consideration as true and real of a fantasy or illusion; and to represent an image that, in a supernatural way, is appreciated through sight or through a recreation of something imaginary.
Taking into account these meanings, some of the examples that can work to explain everything we have underlined would be the following: "The young man had a ghostly vision while he was sleeping in the abandoned mansion" or "The medium has had a vision of what could have happened to him. to the missing boy ”.
In the same way, it should be emphasized that this type of vision also occurs in certain people who are sick. Specifically, they are suffered by those who are living a moment of psychosis, that is, those who for some specific circumstance are experiencing a mental state that takes them away from reality.
The aforementioned patients who will not only have those aforementioned visions, both auditory and visual, but also suffer from sudden changes in behavior, loss of memories, depressions, and feelings that people are observing them and even that they are plotting something against them. he.
Finally, we can mention the business vision , a component of the planning process of a company .
