What is the sense of sight?

The sense of sight or vision (in English Vision) is one of the five basic senses in the human body, and it is the one that allows you to see everything that surrounds you, through a delicate system resulting from the union of parts of the eye with some parts of the brain, so they work together according to fast, specific and accurate steps.

The mechanism of the sense of sight and how vision takes place

The stages of the process of seeing and interpreting things occur in successive steps and are as follows:

1. Light enters the eye through the cornea, and then the lens. During this process, the pupil of the eye enlarges or decreases in order to control the rate of light entering your eyes.
2. The cornea and lens bend or break the light that falls on them, so that what you see can stand out.
3. The light then reaches the retina at the back of the eye, which converts the images into electrical and nerve impulses and signals.
4. The optic nerve transmits signals to the brain, especially to the part responsible for vision, which is known as the visual cortex. The optic nerve can transmit signals from both eyes at the same time.
5. The mind then interprets the thing that you saw, as it collects visual signals and information from the eyes, and then combines them into one clear and explicit image that you perceive in a very short time.

Conditions that affect the sense of sight

3- Various diseases

There are many diseases that negatively affect your sense of sight, such as glaucoma, which damages the optic nerve of the eye, and thus the ability of the part of the brain responsible for vision may weaken and fail to convert eye signals into clear images.

4- Growth disorders

5- Exposure to infection

Infection can greatly affect any part of your eye, thus affecting the eye’s ability to see and see.

6- Ocular refractive disorder

In the event that your eye is unable to bend and bend the light properly, this may expose you to vision problems as well, and this condition causes a weakening of the eye’s ability to focus in addition to blurred vision, and it is a very famous condition that can be treated with glasses and vision correction procedures.
