DEFECTIVE EYESIGHT.

The number of people with defective eyesight is increasing very rapidly, and hundreds of otherwise perfectly fit and healthy men have been rejected foi service abroad by the military authorities on this account, yqt fifty years ago defective vision in young and middle-aged people was comparatively rare.

•The amount of study and reading that roust be gone through by young jpeople in' order to keep up with tli«: standard of modern education is the chief cause of most eye troubles. A'J medica! authorities are agreed on this point, and the fact that a great deal of this reading and study takes place in oadly lighted looms accentuates the danger. This applies particularly to country districts, where it is quite common to find three or four children reading books or papers, and all depending for light on a dim kerosene lamp or acetylene jet. Under such conditions it ir, almost impossible for ths eyesight to remain perfect.

Many eoiintry residents are overcoming the ligr.ting problem by arranging with Messrs Early 'Bros., 59 Cuba street, Wellington, to instal "Wizard" Incandescent Gas-lighting Systems in their homes. The lamps supplied with these systems give a light that is a nearer approach to daylight than any other artificial light produced, and users of the "Wizard" find that they can read and study for hoii-.f at a time without tiring the eyes. The best way to test- the quality of an artificial light is to examine a piece of dark 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. Colors can be distinguished with a ''Wizard" Lfglit just, as they can by daylight. People evon in large towns where coal gas is available are giving U P the local gas supply and purchasing "Wizard" Systems. Mr. Stockwell, the well-known dentist at Palme'rston North, dispensed With the town gas because the "Wizard" gave a better light for much less cost. The following lettei has been received by Early Bros, from this gentleman:— "J have much pleasure in forwarding you cheque for the installation of the 'Wizard' Light. For a considerable time I have been dissatisfied with the borough gas, for two reasons: Ist, its expense; 2nd, of its dirtiness and poor light. My wife was much against making the experiment of having the 'Wizard' Light put in. We have had the 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, cc.s'ing, say, 9s. In the paet our gas bill was quite '2ss a month. Your light illuminates my dining-room 123 ft liiu x 16ft Bin) brilliantly, and gives a much better light than two of the borough gas lights did. "Yours faithfully, (S'gncd) T. G. Stockwell, "Dental Surgeon, "Pulmerston N." Further particulars of "Wizard Lightipg SystemS" may be obtained from Early Bros., 59 Cuba Street, Wellington. GO
