Physics of the Human Eye Essay -- Sight Seeing Eyesight Papers
Physics of the human eye. The human eye, what a complex but fascinating organ. It has the ability to see past the horizon and observe the different colors of a rainbow. The eye can be quicker then a race car but slow enough to witness a snail crawling across a beach. The eye can capture objects at various different angles, such as birds flying overhead or a person walking right beside you. Yes indeed, the eye is probably the greatest sense a person can have. The eye is so vast and complex. To try and write everything about the eye would take a very long time. Compiling all the information and then putting it down on paper, a person could write another book. The eyeball it self weighs about 7gm., the volume 6.5cc., and its specific gravity 1.077. It measures 24.15mm. anteroposteriorly, 24.13mm, tranversely at 23.48mm, vertically in adult males and 0.5mm in each dimension in females. (3) Because the eye is so complex, there are many questions that might come to mind when it concerns the break down or conditions that is brought upon the eye. 1st, What happens to the eye during the gradual age of time? 2nd, How do eye glasses or contact lenses influence the eyeââ¬â¢s capability of seeing better? 3rd, In worse case circumstances, what occurs to the eye if there is trauma brought on like an accident that directly affects the way a person sees or if the eye is diagnosed with a disease that will eventually lead to blindness. The best way to explain how the optical component of the eye works and fails is to compare a healthy normal eye to an abnormal eye. The eye, in general is sheltered by a protective covering known as the sclera which surrounds the eye except for in front where the cornea is located. The cornea sits on top of the ... ...r vision, should get an eye examination. Regular examinations are important, especially for older people and those at high risk groups.
