Causes of Night Blindness and Possible Treatments ------------------------------------------------------------------------------ QUESTION: I read your column each day in our local paper and find it most informative. Can you tell me if it is true that there is a medication for night blindness? I have heard that if one has a problem driving after dusk, it is possible to buy a pill to cure this. True or not? ------------------------------------------------------------------------------ ANSWER: Possibly true, probably not. It all depends upon the cause of your night vision difficulty. And there is more than just one possibility. If your night vision is poor due to a Vitamin A deficiency, theoretically "a pill" could be purchased that would solve the problem. Actually it would have to be more than just one pill, and you would have to take the vitamins over some time, but a single therapeutic substance could remedy the situation. However, night blindness due to a lack of this vitamin is rare today for seldom is the vitamin deficiency that severe. However, night vision problems can also be caused by cataracts and glaucoma, even in their early stages. In addition, older folks have a bit more trouble with dim lighting, and their eyes have less ability to adapt to dimness after a sudden glare of light, as from the headlights of an oncoming car. If you are experiencing this problem now, and you are an active driver, don't delay. Have your eyes checked, and keep your after-dark driving to a minimum until you have discovered the cause and corrected it. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
