Blind Spot

The Blind Spot is the site where the optic nerve exits the retina (optic disc). This area lacks photoreceptor cells and therefore no cones or rods, so it does not perceive light.

Even though there is a blind spot, we usually don't notice it because the brain takes in information from the surrounding areas of the retina. However, under certain conditions, a blind spot may appear.

The blind spot has a diameter of about 5-7 degrees of the visual field, which is approximately 6-8 mm on the retina. It is located 15-17 degrees lateral (outward) from the point of gaze fixation.

The anatomical name of the blind spot is punctum caecum (lat. point of blindness). This is because when looking directly at a blind spot, it appears to be a point where vision is absent.

Thus, a blind spot is a small area of ​​the retina that lacks photoreceptors and is unable to perceive light. Despite this, thanks to the brain, we do not perceive the presence of a blind spot under normal conditions.



A blind spot, or blind spot (Latin for “blind spot”) is an area in the human visual field where photoreceptors are absent. This is where the optic nerve exits the retina. There is no perception of light in this place, since there are no cones and rods here.

Anatomically, the blind spot is located in the center of the visual field, at the intersection of the visual lines coming from both eyes. The space within the blind spot is inaccessible to the eye's perception. It is a circular area with a diameter of about 10 degrees.

The absence of cones and rods in the blind spot is explained by the fact that they are located on the periphery of the retina and do not fall into this area. The blind spot is one of the main factors influencing the perception of depth in space. It may also be associated with vision problems such as glaucoma, cataracts and other diseases.

To compensate for the lack of light in the blind spot, the brain uses other perceptual mechanisms, such as eye movements and changes in focus. However, despite this, people may still experience discomfort and difficulty perceiving space in this area.

Thus, the blind spot plays an important role in our perception of the world and can influence the quality of our life. Therefore, it is important to understand how this area works and how it can be used to improve vision and spatial perception.



A blind spot, or blind spot, is a place in the pupil that cannot see light. It is located on the back of the optic nerve in the eyeball. The optic disc is part of the visual analyzer, which transmits nerve impulses from the eyes to the brain. It consists of axons of neurosensory cells
