What is the perception of light?
The perception of light is a process by which the body or device created by man perceives and interprets light from the environment. To do this, light must first achieve a form of an organ or device that can receive visual input, such as eyes that have many organisms. When the light hits an organ or a light -renowned device, there is a form of processing, as with the brain or computer system to turn the sensory input to meaningful perception. In some cases, the perception of light can only provide information about whether there is light. In other cases, as in the case of human perception, light provides detailed information about the external environment in the form of colors, spatial data and well -defined shapes.
The first part of the perception of light occurs when light from a source interacts with a sensory organ such as the human eye. The human eye, as well as many other types of organic and artificial sensory apparatuses, can Focus about KONKRiet environmental features, thereby involving the selective perception of light. The raw sensory input is converted into nerve pulses in the case of human and animal vision or into electrical signals for computer visual equipment. Organs or devices capable of receiving sensory entry are unable to perceive themselves because perception requires the processing of sensory input.
neural or electrical impulses are interpreted by a brain that creates a detailed representation of the external environment in humans. This processing is an interesting problem for psychologists, cognitive scientists and even philosophers. Neural processing is an essential mediator between the outside world and the perception of human light, so people actually do not see the accurate replication of the world as objectively. How exactly, neural processing affects the perception of light and a kind of world differs from the "world in itself" is unknown.
wideThe range of various human diseases and disorders has a harmful effect on the perception of light. Any direct damage to the eyes or parts of the brain responsible for the processing of visual stimuli, for example, can significantly disrupt or even completely deactivate the perception of light. Similarly, some people are unable to perceive certain colors or any color at all, while others are born completely blind. In addition, diseases and disorders such as cataracts, glaucoma and diabetic retinopathy can all lead to impaired vision. Various treatments and therapy-dokonce and nerve implants-for fight against such problems based on perception have been developed.
