Fotoretseptoreid

Fotoretseptoreid, also known as photoreceptors, are specialized cells in the retina of the eye that are responsible for detecting light and converting it into electrical signals that can be interpreted by the brain. There are two main types of photoreceptors: rods and cones. Rods are responsible for vision in low light conditions, providing black-and-white vision and are more sensitive to light. Cones, on the other hand, are responsible for color vision and detail in bright light conditions. Each type of photoreceptor has a unique structure and function, with rods containing a single type of opsins and cones containing three different types, each sensitive to a different color of light. Photoreceptors play a crucial role in vision, and their proper functioning is essential for maintaining good eyesight.
