The greatest fatigue from lighting, however, lies in the question of glare and reflection. One sees examples of this everywhere. It is caused largely by a misplaced pride in equipment or machinery, and by keeping everything in a high state of polish. One is often disturbed and inconvenienced in even the best equipped public libraries by the glare of the electric lights upon the shiny, varnished, or otherwise highly polished surfaces of the desks. Oftentimes we see lights carefully placed so that the individual gets light enough with his light in the right location, while lights in the distance shine in his eyes. Even when the lights are provided with adjustable shades, it is almost impossible to place one’s book in such a position that reflected light will not shine from the page to the eyes. The glare from nickel-plated machinery, be it a large factory machine or a typewriter, or any other kind of shop or office equipment, will cause fatigue, if the eye is required to work constantly in the vicinity; but the source of fatigue is not recognized. A dull black finished machine may not be as beautiful either to manufacturer or purchaser as would be a shiny, nickel-plated machine of the same design, but the main question is, “How much comfort will the operator take while using the machine?” The kind of finish of such machinery is usually affected greatly, if not determined wholly, by the question of salesmanship. Good appearances have always been a large element in making sales, and it is natural and right that the manufacturer should like his product to be attractive in appearance, and that the manager should take pride in the looks of his factory or office. But our entire standard of what is desirable in “good looks” in a work place has changed. We look now for efficiency and fatigue elimination rather than for ornament and glaring polish. We reduced fatigue, annoyance, and distraction on several pieces of work by having our clients paint nickel and other bright parts with a coat of dull black paint. For the best results to the eye, the same finish as that on the inside of a camera is to be recommended.
