Ionic Theory of Vision

The ion theory of vision was proposed in the 1950s by Soviet physicist Igor Lazarev. It is based on the assumption that visual images are created as a result of the interaction of photons of light with electrons in the retina. Lazarev proposed that vision occurs as a result of the exchange of energy between photons and electrons, leading to the formation of ions in the retina.

According to this theory, each photon of light contains energy that is transferred to electrons in the retina, causing them to become excited. The excited electrons then return to the ground state, emitting light in the form of a photon. This process occurs several times, and each time the photon energy decreases and the electron energy increases. As a result, a series of photons with different wavelengths and intensities are created in the retina, which are then transmitted to the brain to be processed and create a visual image.

Lazarev's theory of vision has received wide recognition in scientific circles and continues to be studied to this day. However, it cannot fully explain all aspects of vision, and many scientists continue to work on more accurate models of the visual process.
