Parts of the Eyes Cornea: protects the front of the Iris: olor of the eye the shape of the pupil influenced by the iris Pupil: electromagnetic waves of light enter the eye through the pupil Lens- reflects light into the back of the eye - Accommodation: change of the thickness of the length depending in how far or close an object is - Near and Far sightedness; astigmatism Retina: Photoreceptors convert light energy into neural energy Cresbisopia: middle age farsightedness Function if the cone allows us to see color. 3 different type of cones Some cones have an action potential when hit by long wave lines, red pigment Some cones to medium wave lengths, green pigment Some cones to shorter wave lengths, blue pigment Rod for darker conditions Additive Color mixing – the number of colors that are reflected by surfaces
