Show I WHY EYESIGHT FAILS M INFERIOR ARTIFICIAL LIQHT FRE- B QUENTLY THE CAUSE. H fllumlnants of the Past, One and All, H Have Serious Defect Acetylene H Gas, with Its Clear, Unwavering, Yet H Soft Flame Cannot Hurt the Eye. H Chicago, June 20. No one can M to Into our nchools or meet n m group of children on the street H without noticing hov large a number M of them wear spectacles. The propor- B tlon scorns to Increase yearly, and m thcro are many more who ought to M wear glasses. The experience of one H teacher might be duplicated by the M score, Sbe knew Alice was lnatten- H tlvo and she thought she was unusual' H ly stupid.' She said eo to the principal H nnd sent a noto -to tli mother, rd- H questing that the child be helped at m homo if she wished her to keep up H with her class. One day after a black- H board explanation, the teacher called H upon the child and found that sho H bad not seen what had been written. H Sho was kept after school and by dint H of much sympathetic questioning Miss H O. found that Allco had novor been 1 able to sec what was put on tho board WM and that hor head had ached so often H and so hard that she frequently failed M to hear what was said. Stinh a condition may be caused by lack of proper food, but In our Ameri- can homes it is usually duo to the H poor quality of the artificial light. Tho M yellow, lnsufllclent light of tho ordi- B nary kcroscno lamp, with its smoky H chlmnoy, is about as bad for tho eyes H as can bo Imagined. Tho flickering B light from a coal gas Jet is but little PH better, and oven tho electric light, H brilliant as It usually Is, ha'a an un- M steadiness duo to variations In power, M and a glare peculiarly trying to the B delicate nerves of Bight. The compar- H atlvely now lllumlnant acotylono gas M produces as nearly perfect an artificial M light as has yet boon found. It gives PH a clear white, unwavering light, very PH brilliant yet perfectly soft, and so PPJ nearly like tho rays of tho sun that PPJ oven colors appear as in daylight. PPV Fortunately, ncetyleno Is very easily PPJ nnd cheaply produced, and tho simple PH apparatus necessary can bo purchased PP and Installed in any homo at a very PPj modornto cost, anil the acetyleno can PH bo piped to convenient points in tho PH houso whero a light Is needed. It is PH , thon lighted and extinguished and used Bx exactly liko common city gas. ' ttVi Acetylene is rapidly coming Into PpB common use In homes, churches, PPK, schools and institutions of nil kinds, Bfey' nn(l " 'B reasonable to expect that as PPpPl its, ilso inHheihomo Increases, there-ppK, there-ppK, 4T" "' ' w'lll bo fowor defectlvo oyes, pnrtlcu- PPV larly among children. Poor eyoslght? PPJ and tho many ills resulting therefrom PH will undoubtedly bo much reduced by PB tho uso of this now lllumlnant. |
