Question

Чому сліпа пляма ока не заважає людині бачити предмети цілісно

Answer 1

В нормальном глазу лучи света не фокусируются на слепом пятне, а фокусируются чаще всего на жёлтом пятне

Answer 2

Why doesn't a blind spot in the eye interfere with a person's ability to see objects as whole?

The blind spot in the eye is an area on the retina where there are no photoreceptor cells, specifically the area where the optic nerve exits the eye. Despite this blind spot, humans are still able to perceive objects as whole without any noticeable gaps or missing information. This is due to a process called visual filling-in, which is the brain's ability to fill in the missing information from the blind spot based on the surrounding visual information.

When light enters the eye, it is focused onto the retina, which contains millions of photoreceptor cells called rods and cones. These cells convert light into electrical signals that are then transmitted to the brain via the optic nerve. However, because the optic nerve exits the eye at a specific point on the retina, it creates a blind spot where there are no photoreceptor cells to detect light.

Despite the blind spot, our brains are able to compensate for this missing information by using the visual information from the surrounding areas. The brain compares the visual information from the two eyes and fills in the missing information from the blind spot based on the patterns and context of the surrounding visual scene. This process is known as visual filling-in.

Additionally, our brains are constantly making predictions and assumptions about the visual world based on past experiences and knowledge. This helps to fill in any missing information and create a coherent and complete perception of the visual scene.

In summary, the blind spot in the eye does not interfere with a person's ability to see objects as whole because the brain is able to fill in the missing information based on the surrounding visual information and make predictions about the visual world.
