SECRETS OF HEALTH

LAEvIFS THAT HELP THE EYES To the vast majority of flic public Uio lighting oi the rooms in which they live and work is a. matter ot the most vital importance, writes Sir W. Arbutlinot Lane, in the ‘Daily Mail- His therefore a. striking fact that the subject el illumination is hardly ever dealt with scientifically. Either the candlepower is insufficient, or the lamps arc placed ill an altogether unsuitable position, or open filament lamps, which dazzle tho eyes, are used. In most cases the matter is lelt to a builder or decorator who has no knowledge of the laws of light and still loss of the manner in which unsuitable lights in bad positions arc responsible for so much discomfort, mental irritation, headache, and, indeed, for very much definite disease of this age. Manufacturers of electric lamps have devoted an immense amount of time to evolving the best forms oi lamp. By covering the globe with a thin trail.-'-lucent layer of china clay, which cuts off only 4 to 5 per cent, of the candlepower, the glare of the incandescent filament is removed, and a great- dill'eienco in the character oi the light results. This advantage may be accentuated ami also rendered more attractive by coloring the day. Orange, yellow, green, blue, and flame tints are the colors that are most popular, varying with the taste of the individual and tho decoration of the room. When used in private houses especially they serve to soothe the eyes and brains, over-stimulated and .somewhat exhausted alter a long day’s work. Internal “ frosting,” again, by tho action of a. powerful acid, produces a lamp costing no more than tho older glaring filament lamp, while it effectively screens the filament and totally eliminates glare and dazzle. To tho writer and student so largely dependent upon artificial light this lypo of lamp will be a great boon, since it frees him from so many of the harassing and expensive results of glare, dazzle, or imperfect illumination, the curse of tho last century.
