Mathematics of the Eye and Color Essay examples -- Math

Eye And Color The eye form a â€Å"optical image† on the light sensitive cell of the retina. It is very often compared to a camera in it so workings. However it is like a camera in its focusing properties but is very different after the light has hit the retina. The camera just prints a point to point representation of the image on film, where as the is much more complex and interesting. The visible light is only a very small portion of the electromagnetic spectrum and various wavelength in this visible spectrum of light represent different colors. Short wavelength light is reddish, medium wavelength light is greenish and long wavelength light is bluish. This make apparent in the a schematic of electromagnetic radiation below. The various structures of the eye refract the light entering the eye to focus is on the photosensitive retina. This structure are like the lenses we studied in class. Path The light takes * Cornea - The transparent tissue (part of the sclera) towards the front of the eye. Nearly a spherical and accounts for 43 of 59 of the dioptric power of the eye. Light must pass through the cornea to enter the interior of the eye. Imperfection in the spherical shape of the eye, astigmatism, result in vision problems. * Pupil- opening to the interior of the eye is controlled by the iris. Iris is the thing pigmented smooth muscle part of the choroid. Pupil controls the amount of light entering the eye by dilating or constricting. The diameter of the pupil can range from 2mm to 8mm. * Aqueous Humor- The liquid between the cornea and lens that has a refractive index (1.336) very close to water. * Lens-flexible tissue suspended from colliery muscles which can be used for accommodation. ... ... for all the visual phenomenon, remember the trick with the four colorful squares towards the beginning of the section. That phenomenon and many other like can not be explained with tricromatic theory alone, so a combination of tricromatic theory and opposition theory are used to explain vision. But the trichromatic system works at the retinal level where as the opposition is at the cerebral level.
