SUNLIGHT AND Cl-IROMOTI-IERAPY IN EYE CARE By Dr. M. M. Spigel, O.D. Broad-Grace Al'CtlClt',, Riclz-nzond, l'irgin.ia NATURE DEMANDS PLENTY OF SUN- LIGHT Plenty of sunshine. winter and summer, is one of the most effective treatments for both body and eyes-and is the most available treatment for all classes and sections of hu- manity. The beneficial action of the sun depends on the ultra-violet ray, an invisible part of the sunlight, which upon striking the naked skin changes some of the ergosterol ta fatj beneath the skin into that much-need- ed substance-Vitamin D. A prolonged lack of sunlight causes light starvation in certain parts of the physical body and eyes and impairs the circulation of life forces through such parts. which results in diseased organs or possibly malignant growths. Practically everyone has observed that if plants are left in a room where no sunlight can penetrate they soon lose their color and show qualities of parasites. In like manner, a person who lives in a dark room and seldom comes out into the sunshine will become pale and will be subject to all kinds of bacillary infections. especially tuberculosis. In addi- tion, the eyes will appear dull and sluggish: the pupils will dilate. causing a sensitiveness to light Qphotophobiaj. and clark rings will appear underneath the eyes. Animals, through instinct. take sun baths. YVatch a cat or dog follow the sun streaming in through a window or stretch in the sun on the porch or in the yard. Chickens and birds 1nay often be seen lying on their sides, ruffling their feathers in the sun. Since ani- mals and fowls absorb most of the sun rays in their hair and feathers. little sun can reach the skin of the body proper, so it can be as- sumed that they receive in large part health benefits from the sun through their eyes. How often do we hear people complain that they are unable to sit in the sun because it hurts their eyes, or they must wear dark sunglasses to protect their eyes. If the eyes are sensitive to light or glare, it is due to a lack of sunshine Vitamin A. And this needed sunshine vitamin cannot be absorbed through tinted lenses or sun goggles. Tinted lenses will obstruct or neutralize the valuable sun rays, so essential to the eyes and general health, and will increase the eye's sensitive- ness to light. And it has been proven that neither tinted lenses nor sun glasses prevent glare. In fact, they increase the danger of night driving. Sun glasses are not advisable, as they tend to make the eyes more sensitive to light over a period of time and weaken their ability to adapt themselves naturally to various indoor and outdoor lighting condi- tions. Possible symptoms of Vitamin A deficiency and sunlight starvation are: l. Poor vision. 2. Eyes sensitive to light. 3. Poor vision in semi-darkness Qnight blindnessj. 4. Red and swollen eyelids. 5. Squinting. 6. Dryness of the eye membranes. In the retina at the back of the eye is a substance called visual purple. This pigment plays a very important part in the sharpness of the eyesight, especially in the ability to ad- just the eyes from a bright to a dim light. Vitamin A is one of the chief materials from which the body builds visual purple. A lack of sunshine and the failure to include suf- ficient Vitamin A in the diet slows down the regeneration of this substance that helps us to see in a dim light. Other causes, of course, could contribute. Under-corrected farsightedness Qhyperopiaj PAGE THREE
