DEFECTIVE EYESIGHT

WHY IT IS INCREASING. The number of people with defective eyesight is increasing very rapidly, and hundreds of otherwise perfectly fit and healthy men have been rejected for service abroad by the Military Authorities on this account, yet fifty years ago defective vision in young and middle-ai;cd people was comparatively rare. The amount of study and Teading that must he 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 the fact that a great deal of this reading and 6tudy 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 light on a: dim kercn sene lamp or acetyleno jet. Under 6uch conditions it is almost impossible for tha eyesight to remain perfect. Many country residents are overcoming the lighting problem by arranging with Messrs..Early Bros.. 59 Cnba. Street, Wellington, to install "Wizard" Incandescent Gas-]ighting, Systems in their homes. The lamus supplied with these systems give a light that is a nearer approach to daylight than any other artificial lieht produced, and users of the "Wizard" find that they can read and study for hours at a time without tiring the eyes. The best wav 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 blua cannot be distineuished from black. Colours can be distinguished with a "Wizard" Light as they can by daylight. People oven in large towns where coal gas is available are giving up the "local "as supply and purchasing "Wizard" Systems. Mr. Stoctwell. the well-known dentist at Palmerston North, dispensed with the town Eras because the "Wizard" <">Ye 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 vou cheque for the installation of the 'Wizard' Light. For considerable time J have been dissatisfied with the Bor-ous-h- Gas for two reasons: Ist, its'exnciise; 2nd, of its dirtiness , and 'poor light. My -wife was much against -makinc the experiment of having the 'Wizard' Light put in. We have had the liirht in now for two months, and mr wife Tvo"ld riot stand the Boroudi Gn's again. We have not yet up°d one tin of benzine, costing, sav. 9*..-In the nur gas bill was onite 255. a month. Tour light illuminates my dining-room (?3ft. Sin. x ICft.
