The sense of sight

Sense of taste

Powerful, complex and fragile, the eye is the most sought-after of our five senses. As our vision is a precious asset for learning, working and developing to the full, it is important to correct it, protect it and prevent possible problems or pathologies.

What we see is never totally reality. What we see is a composition made by our brain from perceptions and visual sensations. In the same way, a photo, which is a flat version of a 3D world, can never resemble what our eyes see.

THE SENSES OF SIGHT: It is one of the most evolved senses. It allows us to capture and interpret visual information about light, color, shape, distance, position or movement. Its receptor organ is the eyeball (eye) and is housed in the orbital cavities. The anatomy of the eye consists of the following parts:

How vision works

Vision is the ability to interpret the environment thanks to the rays of light that reach the eye. Vision, or the sense of sight, is one of the main sensory abilities of humans and many other animals. World Sight Day is celebrated on the second Thursday of October.

When light enters the eye, it passes through the cornea, pupil and lens to reach the retina, where the electromagnetic energy of light is converted into nerve impulses that are sent via the optic nerve to the brain for processing by the visual cortex. The complicated process of visual perception takes place in the brain, thanks to which we are able to perceive the shape of objects, identify distances, detect colors and movement. The retina is one of the most important regions of the eye and contains specialized cells called cones and rods that are sensitive to light.[1] Injury to any of the structures of the retina can cause damage to the retina.

Injury to any of the structures of the visual system can cause blindness even if the rest of the visual system is unimpaired. In cortical blindness, for example, caused by a lesion in the occipital region of the brain, complete loss of vision occurs even though the eye and optic nerve are unimpaired.[2][3] In cortical blindness, for example, caused by a lesion in the occipital region of the brain, complete loss of vision occurs even though the eye and optic nerve are not abnormal.[2][3

Human eye

The sense of sight is the most developed of the five senses we have and, therefore, the most important of all. This is due, in part, to the fact that we live in a world that has historically given priority to visuals and images.

The sense of sight is the most important simply because it is thanks to it that we carry out a large part of our day-to-day activities. It is a cultural issue, since almost all of our environment is related to the ability to look at things and analyze them, especially since the advent of new technologies (cinema, videos, electronic media, etc.).

The sense of sight, therefore, is the most important of all, so we must take care of it in terms of nutrition and rest, as well as sun exposure, exercise and relaxation, without forgetting to visit the ophthalmologist regularly.
