Do you see? (1935)

thousands of years ago primitive man developed his keen sight by constantly having to use his eyes in searching for foes and food then in the middle ages with the advent of writing ice strain began to appear the monks writing in the dim light of their narrow cells were the first sufferers and so eyeglasses came into being crude at first but gradually improving necessity being the mother of invention many years ago if you had any doubt about your eyesight being good you probably went to a place like this where the tests were more like a spelling lesson than an optical examination while even today old-fashioned methods of eye testing are still used in some places how beautiful eyes can be yet it has taken thousands of years to learn the importance of caring for them properly nowadays however we are able to seek the advice of a doctor with special knowledge of the eyes and a private consultation should be the first step in treating all cases of detective site it is the brain that actually sees not the eyes behind the cornea is the iris the colored part of the eye around the pupil the opening which adjusts itself to varying degrees of light the image is focused on the retina and transmitted by the optic nerve to the brain if this nerve is destroyed the image does not reach consciousness and blindness results the eye directly affects and is affected by the bodily health and conditions only a doctor has the medical knowledge and experience necessary to treat defects in a living organ therefore it is most important to seek the skill and knowledge of the medical eye specialist immediately the site becomes troublesome so many diseases show their first symptoms in the eye that skilled examination of the fundus or back structures of the eye is of the greatest importance any change in color or condition is carefully noted in many cases the eye specialist finds it necessary to make use of other appliances in addition and finally having assured himself that the trouble is not caused by bodily defects he tests the patient for imperfections of sight some people are color blind and in these days of color traffic signals everyone should be examined for this particular defect which strangely enough afflicts more men than women and so the examination goes on until the eyes have been completely tested then if necessary the eye doctor gives the patient a prescription for glasses to be made up by a qualified dispensing optician for inaccurately made glasses do more harm than good careful measurements are taken so that the flames may fit comfortably and in the correct position and when made they are tried on to ensure that every detail is correct who said the glasses were not attractive medical examination of the eyes is so necessary to the health and well-being of the public that a national scheme has been brought into being by the british medical association providing for all of limited means an examination of the eyes by an eye doctor and glasses where necessary at low inclusive charges this scheme known as a nationalised service is available in all parts of the country over 900 medical eye specialists having generously consented to examine patients neglect may easily cause you lifelong regret if your eyes worry you consult a medical eye specialist if you cannot afford to do so privately ask your doctor about the nationalized service we'll repeat that on the screen for all of you with a blessed gift of sight to read and remember
