The cones are less sensitive to light than the rods, as shown a typical day-night comparison. The daylight vision (cone vision) adapts much more rapidly to changing light levels, adjusting to a change like coming indoors out of sunlight in a few seconds.
Do you have more rods than cones?Rods are more numerous than cones in the periphery of the retina. There are about 120 million rods in the human retina. The cones are not as sensitive to light as the rods. How many rods and cones do humans have?
Do cones or rods need bright light?Vertebrate eyes function reliably over twelve orders of magnitude in light intensity by employing two types of photoreceptors. Cones function well in bright light, but high levels of intrinsic noise make them unreliable in dimmer light. In contrast, rods have low levels of noise and function well in dim light.
