The evidence that substantiates Young’s hypothesis. Introduction: The cones and rods are the photoreceptors. The cones, as well as rods, contain rhodopsin (light-sensitive pigments). In each human eye, there are around 1 million cones and 125 million rods. The function of the cones is to perceive color.

Human color vision is "produced" by the nervous system based on how three different cone receptors interact with photons oflight in the eye. These three different types of cones interact with photons of different frequency light, as indicated in the following chart:

Here you see an astigmatism illustration. Please explain why astigmatisms cause blurred vision in the context of our sense of sight. Please do not merely say “The light rays do not hit the focal point”. Please explain why that matters for the sense of sight.

You are watching the stars at night, and you never seem to be looking at the right spot to catch the brightest meteors. Which of the following might explain this? a)Your fovea contains mostly cones; thus you see dim light especially well when looking right at it. b)Your peripheral retina contains more rods, which are more sensitive to dim light than cones; thus objects in your peripheral vision appear brighter in dim light situations. c)Detection of light depends mostly on its color rather than intensity; thus cones play a larger role in detection of light in dim light situations. d) all of the above. ( well explain the correct answer and type answer).
