Document Summary
Absorb range of variations of wavelengths of light (electromagnetic spectrum) This is what give us insight into what we see. Other animals (not humans) have a completely di erent view of the world as they have di erent wavelengths of light that they can see (some can see ultraviolet or infrared which humans cannot) Therefore every animal has a di erent perception of the world. When its dark only use rods (some women have 4 cone types - sensitive to colour and light) Everyone has a unique pattern of photoreceptors (10 people have had their retinas photographed) degree visual system wavelength seen in the one point in time (everything else related to vision is the brain) Pattern not a very good indicator of the individual"s sense of sensitivity. Wiring of the visual system normalises di erence between people to some. Everything you see is only due to the photoreceptors in the retina.
