Document Summary

We can only perceive a small portion of light (visible spectrum - ~380nm (violet) to 720nm (red)) Near-sightedness: eye too long: image focused in front of fovea. Farsightedness: eye too short: image focused behind fovea. Eye, optic nerve, optic chiasm, lateral geniculate nucleus, visual cortex are major components of the visual system. The image projected onto the retina and received by the visual cortex is upside-down and reversed. Light goes through ganglion cell layer bipolar cell layer photoreceptor layer (cone and. Rod) and detected at the back of the eye. Photo strikes photo-pigment photo pigment split, chemical reactions produce message . Message is transmitted to bipolar cell message transmitted to ganglion message is sent to brain. A huge amount of cones at the fovea. (cones detect colour) few cones in periphery. There are more rods at the periphery, no rods at the fovea and the optic disk.
