Show F.llrtrlc Lilslita and Kyeiiliclit. Dr. John A. Payne, oculist says; 'Most persons who use the incandescent incandes-cent electric light like a new lamp he-cause he-cause the light is whiter and more brilliant bril-liant than after the lamp has been in use lor two or three weeks. This is wrong:. It is the dazzling white light that harms the eve. An old lamp is the boat, for in these the light has become changed to a pale yellow, which is the ideal color. Just as in noonday brightr ness human sight is not so elear and far-reaching as at the yellow sunset, so a new incandescent burner is not so j good for the eye as an old one. An old burner so adjusted and shaded that the light from it does not shine in the face, is the ideal artificial light. An argand gas-burner comes next. The use of the are light should bo eonfiuod to street lamps. Some storekeepers still use them, but they are terribly hurtful to the eye. This is because the intensity of the light is constantly changing, and this jumping of thq blaze is much worse for the eye than the nicker of the gaslight. I have had occasion to treat a great many people for inflammation of the retina caused by the light of arc lamps." St. Louis Globe-Domocrat |
