![]() ![]() For example, a yellow object - such as a banana - stimulates the red and green cones simultaneously, as red and green combine to create a yellow hue. More than one color cone is stimulated to see the colors in between. Red light and objects stimulate the red cones, while green light and objects stimulate the green cones and so on. There are three subtypes of cones: blue, red and green cones - each is sensitive to various wavelengths of light, which allows the eye to see multiple colors. This type of photoreceptor contains proteins called photopsins (or cone opsins) that help create color pigments for the eye to view. Cone photoreceptorsĬone photoreceptors are activated by bright lighting and help the eye to see color. The human eye contains more rod photoreceptors than cone photoreceptors. Rods aid in night vision and identifying black and white hues.īoth cones and rods contain special proteins that assist in their functionality. While cone photoreceptors detect color through bright light, rod photoreceptors are sensitive to low-light levels. These cells function by sensing light and/or color and delivering the message back to the brain through the optic nerve. There are two types of photoreceptors: cone photoreceptors and rod photoreceptors. Each type of photoreceptor works to convert different levels of light into signals that are then sent to the brain to form a visual representation. ![]() There are two kinds of photoreceptor cells: cones and rods. Photoreceptor cells are located in the retina, which is the light-sensitive tissue that lines the back of the eye. Small cells called photoreceptors in the eye play a vital role in night vision and also affect how the eye sees color. ![]()
