Vision

movement and change in light intensity.

Vision is one of the most important senses for many living organisms. It allows you to navigate the world around you, find food, avoid danger and find partners for reproduction. Almost all living organisms, even the simplest, have light-sensitive cells that are responsible for vision. However, in higher animals this sensitivity to light is localized in specialized cells, which provides higher accuracy and clarity of perception.

The human eye is an excellent example of an extremely sensitive and specialized organ for sensing light. With the help of the eyeball and other structures, the human eye is able to focus light on the retina, where the light-sensitive receptors - cones and rods - are located. Cones are responsible for the perception of color and detail, and rods are responsible for the perception of movement and changes in light intensity.

However, other animals also have their own specific ways of perceiving light. For example, flatworms (planarians) have “eyes” that allow them to determine the direction of a light source. Many sea worms have well-developed eyes and other sensory organs located on the head. Insects and crabs have complex compound eyes that create a mosaic of images.

In addition, vision can be adapted to different environmental conditions. For example, at night, the eyes can adapt to darkness, allowing them to see in low light conditions. Other animals, such as earthworms, may use light-sensitive cells on the skin to sense changes in light and other environmental factors.

In summary, vision is an important sense for many living organisms, and it can be implemented in a variety of ways depending on environmental conditions and evolutionary development. Understanding vision in different animals can help us better understand nature and its diversity, and help us develop new technologies to improve vision in humans and animals.

👀 VISION IS THE SCIENCE ABOUT THE NATURAL WAY OF INFLUENCE OF LIGHT AND FURTHER TRANSMISSION OF LIGHT SIGNALS TO THE BRAIN OF HUMAN AND ANIMAL, BY WHICH THE FORMATION OF AN IDEAL IMAGE IS CONDUCTED. THE VISION OF THE ORGAN PLACES ONE OF THE MOST IMPORTANT ROLES ON THE EARTH.

👁️ THE ORGAN OF VISION IS THE SCIENTIFIC NAME FOR THE EYE, THE DIAMETER OF WHICH IS ON AVERAGE EQUAL TO 24 MM, AND THE WEIGHT reaches 6 G. DEPENDING ON THE CLEAR CONSIDERATION OF THREE SPHERES OF PRIORITY ZONES of action of the human eye are divided into areas: central, upper and lower peripheral zone. Each zone is characterized by a certain visual acuity, or the ability to distinguish small details of objects and the distance to them. The central zone (area of ​​greatest vision) is about 1.5° angular fields in the horizontal plane and 57° in the sagittal plane. The size of the scotoma area in the center of the visual field determines the angle of action of the Fouque factor for strabismus
