Rods and cones in the eye definition

WebCone dystrophy. The light-sensing cells in the retina come in two main kinds: rods and cones. Rods are extremely sensitive and work better in dim light, whereas cones are more effective in bright light. Cones give us our colour vision and although they exist across the retina, they are densely clustered around the macula. WebThe rods on the retina are concentrated in a ring around the cones; There are virtually no rods at all in the center of the eye; Because rods are mostly located away from the fovea, they are responsible for peripheral vision; This requires a pilot to look off center to see an object at night; Unable to discern color but are sensitive on low lights
