How does the sense of vision work?

The experience of vision begins when photons from the world enter the lens of our eye and focus on a small area of photoreceptive cells in a part of the eye called the retina. These cells represent rods and cones. The cones are responsible for determining the color, they function well in bright light, and the rods are more sensitive. Some have more wands, especially those who are adapted to nightlife. Some owls have night vision 100 times sharper than the vision we are used to.
Cones and rods perform a function called phototransduction, which simply means converting incoming light into electrical signals that need to be sent to the brain, which makes it possible to see. All these cells contain photoreceptive proteins with various pigment molecules. Various pigments can be found in the cones, allowing the eye to distinguish between different colors. When the light associated with the pigment affects the photoreceptor cell, it sends a signal along the optical fiber.
There are two notable structural characteristics of the human retina. The first is the foveola, a highly condensed region of photoreceptor cells located in the center of the retina. The density of cells here is several times higher than in the periphery, which is why when we look directly at something, we see the object much more clearly than if we look at it out of the corner of our eye.
The foveola is also responsible for behavioral adaptations that provoke us to quickly turn our heads and look at something if it scares us. If the foveoli did not exist and the density of photoreceptors was uniform across the entire surface of the retina, we would not need to do this - we only needed to tilt our head slightly to bring the object into our field of vision.
The second notable structural characteristic of the retina is the presence of a blind spot. This is where the optical fiber connects to the back of the retina to receive visual information that excludes the presence of photoreceptors in a small area. Our brain automatically fills in blind spots, and various visual exercises can prove that they exist.
When light is converted into electrical impulses and transmitted to an optical fiber, it travels all the way to the back of the brain (after several stops), where the visual cortex is located. In it, the hierarchy of detector cells isolates useful patterns in visual data, discarding unnecessary information. One layer of cells detects things like lines and curves.
A higher level will determine patterns such as movement and three-dimensional shapes. The highest level is where gestalts appear - common symbols responsible for conscious experience of vision under normal circumstances. The visual cortex is one of the best concepts of all areas of the brain, supported by the literature on neuroscience.
