here is the answer:
The rods and cones respond, respectively to the amount of light energy and to the colours present in it. The rods are responsible for the vision in dim condition and the cones helps us in colour vision. The cones get activated only in bright light conditions.Our eye contain 7million cones which helps us see the colours and the details of the object. Also, there are 120million cones which helps us to see better in dim light conditions.

Hey mate here is your answer
There are two types of photoreceptors involved in sight: rods and cones.
Rods work at very low levels of light. We use these for night vision because only a few bits of light (photons) can activate a rod. Rods don't help with color vision, which is why at night, we see everything in a gray scale. The human eye has over 100 million rod cells.
Cones require a lot more light and they are used to see color. We have three types of cones: blue, green, and red. The human eye only has about 6 million cones. Many of these are packed into the fovea, a small pit in the back of the eye that helps with the sharpness or detail of images.
Hope the answer helps you and if you are satisfied plz mark as brainliest
