WebHumans have two types of receptors for vision. Rods and cones. Rods work under dim lighting conditions, whereas cones function under bright lighting conditions. Rods and cones are located on the retina, a thin layer in the back of the eye. In the dark, we cannot see colors because there is only one kind of rods. WebThese mutations lead to the premature destruction of S cones or the production of defective S cones. Impaired S cone function alters perception of the color blue, making it difficult or impossible to detect differences between shades of blue and green and causing problems with distinguishing dark blue from black.
