Sight (including color vision) Biophysics of Primary Mechanisms

Sight analyzer is the most important human sense organ. We perceive 90% of the outside world through the eye. It participates in formation of representation of objects, their color, shape, size and layout. Damage to individual parts of the vision analyzer causes a variety of violations. That is why it is important to protect sight, adjust to work with appliances (TV, computer, etc.) deadlines, conduct prophylactic medical control. The paper presents light, its properties, elements of geometric optics, eye structure, mechanisms of vision, its initial biophysics, vision disorders and their prevention.
