But they can still see much better than the average digital camera. This is partly due to the photoreceptors (rods and cones) in the eye. Rods are responsible for our night vision and ability to see in low light. They are found primarily in the peripheral regions of the retina, so you may find that they can see better at night if they focus their gaze sideways to what they are looking at. The cones, however, are concentrated in a central region of the retina called the fovea. They are responsible for high visual acuity tasks such as reading, as well as color vision. We can further classify the cone cells into: red, green and blue. Depending on how they respond to red, green and blue light, it enables us and determines how we perceive
