DEFECTIVE EYESIGHT

The number of people Tvitli defective ■eyesight is increasing very rapidly, ancl hundreds of otherwise perfectly fit and healthy meu have been rejected for service abroad by the Military Authorities on this account, yet fifty years ago defective vision in ypung and middle-aged people was' comparatively rare. : • The amount of study and reading that must be gone through by young people in order to keep up with the standard of modern education is the chief cause of most eye troubles. All medical authorities are agreed on this point, and tho fact that a great "deal of this reading and study takes place in badly lighted rooms accentuates the danger. This applies particularly to country districts, where it is quite common to find, three or four children doing home lessons, and the parents reading'books or papers, and all depending for Might on a dim kerosene lamp or acetylene jet. Under such conditions it is almost impossible for the eyesight to remain perfect. Many country residents are overcoming, tlie lighting- problem by arranging with Messrs. Early Bros., 59 Cuba Street, Wellington, to install "Wizard" Incandescent Gas-lighting Systems in their homes. The lamps supplied with these systems give a light that is a iearer approach to daylight' than sny other artificial light produced, and users of tho '"Wizard" find, that they can read and study for hours at a time without tiring the eyes. The best way to test the quality of an artificial light is to examine a piece of (lark blue material, such as serge, in daylight, and then in the artificial light. In daylight the exact shade of the material can be judged, but under electric light and even coal gas the dark blue cannot be distinguished from black. Colours can be distinguished with a "Wizard" Light just as they can by daylight. People even in large towns where coal gas is available aro giving up the local gas supply and purchasing "Wizard" Systems. Mr. Stoclnvell, the well-known dentist at Palmerston North, .dispensed 'with'the town gas because .the "Wizard" gave a better light for much less cost. The following letter has been received by. Early Bros., from this gentleman:— "I have much pleasure in forwarding you cheque for the installation of the 'Wizard' Light. For considerable time I have beeu dissatisfied with the Borough Gas for two reasons: Ist, its expense; 2nd, of its dirtiness and poor light. My wife was much against niakr ing the experiment of having the 'Wizard' Light put in. We have hadi tho light in now for two months, and my wife would not stand the Borough Gas again. We have not yet used one tin of benzine, costiug, say, 9s. In the past our gas bill was quite 255. a month. Your light illuminates my dining-room (23ft. Gin. x lGft" Gin.) brilliantly, and gives a much better light than two of tho Borough Gas Lights did. "Yours faithfully, "(Signed) T. G. Stockwell, "Dontal Surgeon, "Palmerston N." ■ Further particulars of "Wizard Lighting Systems" ■ may be tobtained from Early 'Bros., 59 Cuba Street, Wellington. -G. (Published By Arrangement.)
