Document Summary

Light is made up of particles called photons. The colour we see depends on the wavelength or frequency of the light. The brightness we see depends on the intensity/amplitude of the light. The major structures of the eye are the cornea, pupil, lens, and retina. They bring the rays together to form an upside-down image on the object on the retina, where light energy is transducer into neural impulses. Dark adaptation - describes how the dark adaptation curve shows how sensitivity to low levels of light increases over time. Colour sensitivity - in bright lighting conditions we see colour and in dark conditions we see in shades of grey. Both rods and cones contain photopigments and when exposed to light these pigments change their chemical structure and become white (process is called bleaching). The bleaching causes the photoreceptors to become less receptive to light (become white reflects light). Rod receptors - have another different type of.
