Wonderland of Vision (circa 1948)

never changing ocean and the pleasures of the next time the forms of all creation a wonderland of in the eye is protected by a deep pony side it is marvelously equipped with muscles and the delicate crystal and language truly the eyes of all of wonder nature's masterpiece the iris controls the amount of light admitted the cornea is a protective coating the lens automatically changes shape or near and far see the retina is like a sensitive film on with or like reporters the optic nerve today's impulses to the brain which interprets what we see the purpose of the lens is to bring rays of light to a point or focus and the shape of the lens is all important with no limbs to interrupt their journey rays of light travel in a straight line if we break their journey with the lens that bulges out word we bring the Rays to a focus our lands curved inwards however will spread them apart and so if our eyes had no lenses the Rays would not come to a focus on the retina again the all-important lens focuses raised on the retina so that we record real images a common error of vision is near sightedness the eyeball in a nearsighted I is too long raise focus in front of the retina making everybody look blurred a correcting vast lands in front of our own lens will make things look clear again another seeing error is precisely the eyeball and a farsighted I is too sure raised focus behind the retina again everything looks blurred another kind of lands in front of our own lens will bring things back into focus a thorough examination every year reveals the true condition of our eyesight as well as important aspects of our health to the professional examiner this network of veins and blood vessels at the back of the eye is full of meaning with the aid of ingenious scientific instruments our examiner puts our vision through a multitude of tests and unseen yet forever in the background are the men of vision whose genius inspires every detail Willa thoughts know whose laws of refraction enable us to measure lenses with great accuracy Sir Isaac Newton's experiments would like help lay the foundation of modern optical slam parmesan who taught us much about distorted vision or a stigmatism as it is called on helpfuls the first man to look into the living I and many many more our modern eyesight examiner carries on this great tradition of visual science only years of study experience and judgment aided by precise scientific instruments enable him to uncover and correct the shortcomings of the eyes these might be blurred vision double vision tunnel vision distorted vision and countless other 40 seeing 7 projected on a screen letters symbols figures and colors will help our examiner decide on the best lens powers and curves that will bring our vision to its best possible there will also be many intricate reading tests at normal and varying distances for only by carefully studying all his findings and balancing one against the other can our examiner determine the precise amount of Correction each of our eyes will need our thanks to all the professional men and women of vision everywhere to whom we are indebted for the precision and trustworthiness of a modern high and eyesight examination our thanks also to the technician who interprets would be nut most accuracy the findings of our examiner his job is to take facial measurements to determine the proper size of our lenses he must see that the lens of the properly centered an angle he takes into consideration the exact powers and curves that have been specified to guide us on a choice of frames that will hold our renters are for one carefully calculated distance from our eyes for any classes that are not fitted properly and easily undo much of the examiners conscious work of great importance also give the selection of frame with bridges and temple pieces that really fit our facial characteristics careful fitting is essential if we are to get the greatest benefit from our glasses and enhance our looks and personality my glasses are such simple looking things two lenses in a frame yet how much science and craftsmanship goes into their making what blending of prime skilled what cementing Memphis problem and the constant searching searching for more perfect methods and standards of achievement consider glassmaking there are no greater standards of perfection from those to which ophthalmic glass the glass of lenses have made a pot to hold our glass is made from a carefully balanced play formula it must be free from every place of impurity scientific blending is the secret of the class mix silica theriyum lime led special and rare ingredients from the ends of the earth in the great heat of this blasphemous America will take place the dull opaque stuff of the earth will be transformed into the crystal wonder that makes man master of his sight [Music] starring a long patient job every bubble of air must be speed up the glass texture must be uniform this is a critical operation for long cooking sometimes taking days is finished impurities are skimmed from the surface you you these parts can hold up to 600 pounds of glass yet so high are the standards of quality for a family class that only 40 pounds of Windsor's will successfully pass all their tests glass must be handled with care at every stage it must not cool too quickly or it might back in the annealing ovens where our glass goes next it will be gradually cooled for 12 hours the varieties of ophthalmic glass are endless and it takes 363 lens production skills to make our glass into spectacle lenses when our glass leaves the cooling ovens it is carefully inspected the slightest imperfection waves drive bubbles cloudiness and it goes on the scratchy this man might handle two tons of glass on the course of a days and spectral all phases of glass finishing call for great accuracy skill and judgment this is scouring the carefully measured class into squares or planes and they will now be called the amount of glass in each blank is the gauge to the amount and kinds of curves that can be put on it later and so weighing is important it is done by hand and also an ingenious automatic diamond tip scale up to now our planks have been flat squares here they are molded into round blanks with curved surfaces together conform to the shape of our eyes many fields of science contribute to the perfection of our class 4a scopic writes reveals flaw is invisible to the naked eye [Music] of course many kinds of blanks are made for many different scene purposes these that are being blocked or set in pitch will become a large section in a bifocal this is the dance of the polishing spindles it took years of research to find the right polishing and lubricating compound this man is not a watchmaker this is another number 45 inspections hourglass blank will get before it leaves the factory matching the two sections of a bifocal calls for trained eyes patience and dexterity and because a single speck of dust between the two parts will spoil the finished lens girls work in dustproof air-conditioned rooms every inch of each compartment in the room is carefully scrubbed every morning Benjamin Franklin was the man who first thought of combining two lenses of one or near and far see nowadays we have trifocals three lenses in 14 near point midpoint and far-seeing the little metal pins hold the two sections with a blank and proper position during the fusing operation the electric using furnace is specially designed to rigid specifications it is automatically controlled although only 20 feet long temperature gradations are so critical that our bifocals will take five to eight hours for their journey hourglass cookies already the heat has caused the center of a small lens blank to become fused to the large blank the little pins we saw will afterwards be ground on our two lands pranks have now become one starting with milling some 20 preliminary operations will be performed on our land flank it will receive rough grinding fine grinding all the grades of polishing engaging sorting and wing and of course constant inspection inspection inspection or there is only one standard of the lenses that correct our vision perfection yes sir lens blank looks deceptively simple yet each single bite must go through every one of these stages how much has had to be worked out studies of light the complicated mathematics of seeing miraculous laboratory and shop techniques incredibly precise instruments the analysis of countless class chemistry formulas unending research and experimentation the experience judgment and skill of thousands of artisans craftsmen technician the centuries of devotion to visual science simple indeed yet this piece of glass is the culmination of all man's knowledge and work in the realm of ophthalmic class making ophthalmic class that brings to millions of us on you joy and see and so having made our limbs planks let us find out how we make our frames in metal frames gold is the important ingredient gold is beautiful and flexible it is the one metal that can be worn close to the skin for long periods of time with perfect comfort fine pure gold is also very expensive each of these 24 karat gold bricks is with about ten thousand dollars what gold is soft it is strengthened by mixing it with other metals in our finished frames this precious gold will surround every exposed metal part to turn it into the various thicknesses of wire and cable we need are those will be rolled pressed annealed and drawn it will be heated cooled bathed in chemical receiving the scrupulous attention and know-how of skills gold workers and metallurgy here are some of a 59 parts that go into the gold mounting for our glass lenses bridges temple screws hinges and the number of operations necessary from the gold mouth to the completely assembled time one frame mind you is 456 these operations call for skilled handiwork by trained and nimble fingers to make plastic frames we have borrowed our material from the chemist and our colors from the rainbow plastic frames call for as much dexterity and partnership as metal frames special machines and processes give them that brilliant luster that is really built in they go through many carefully controlled statements it is this unlimited attention to detail that have made American eyeglasses unrivaled for sheer beauty and sound value standards of perfection are maintained with constant checking the frames are mixed with wooden pegs soda and pumice in a very interesting smoothing operation called tumbling and now having made our frames and watched our glass become blanks we come to the very heart of lens work custom finishing in the prescription laboratory to the rigid specifications of our examiner this is exacting work a slip of the hand here and this lens Frank would be ruined after access marking to keep the lens in proper register a wrap or cutting tool will give it the proper curvature flaps can be machined to thousands of differing curves and combinations plus or minus curves spherical and cylindrical curved special curved prisms eyes are as individual almost as fingerprints these custom operations also call for the use of special grinding and polishing materials diamonds garments the finest ruled blends of minerals and substances chosen only after thousands of other plans have been rejected these are only a few of the key operations there is blocking cleaning shaping filling and many many more after that we'll step there is precise measuring check engaging vigilant watch to make absolutely certain our examiner's orders are being carried out to the minutest tail and here are our finished classes mathematically exact to a hair's breadth with a brilliant flawless surface frames and lenses scientifically made an assembled set it in front of our eyes in their one true position to work modern miracles for our vision glasses glasses glasses every shape every size every color of the rainbow scientists artists craftsmen and plastics and precious metals designers chemists professional men and women and a hundred branches of optical science all had a hand in bringing passes to their modern-day perfection glasses are indispensable to seven out of every ten of us young and old all ages required besides giving us flawless visually enhance our personality flatter our features they are also high fashion for all occasions the up to take person has an eyeglass wardrobe to Brandon eyewear with clothes for every activity business sports social engagements having several pairs is also wise in case of loss or breakage how often has our day been spoiled without them our eyesight changes almost from the year to year and our general health and alertness is so dependent on how well we see a regular eyesight examination can do so much for us and if we have that we can count on modern visual signs to keep us abreast of every new development to guide our eyes to help us cherish our vision to bring us the utmost perfection and I care and I wear for the most precious of all our senses vision and what a world of vision this is for the world of activity pleasure and relaxation alright bring us on the job every day of every year indoors and out enriching our life with color beauty and a thousand and one entrancing sites let us not forget many have labored throughout the years to help us see well at all times in every stage of our lives and this labor is unceasing in the multiforme realm of visual science for their vision is king to bring us the glories of nature the wonders of man and to safeguard the eyes of the future in the Wonderland of vision nothing you buy gives you so much yet cost you so little you you
