Leonid Vitalievich Rudnitsky, Doctor of Medical Sciences, professor, author of many medical monographs, wrote this book for older people who know firsthand such serious diseases as cataracts and glaucoma. The eyes are perhaps the most important of the sense organs. Light and shadow, green leaves and grass, blue seas, purple sunset, facial features of a loved one and masterpieces of fine art - all the beauty of the world is given to us by sight. But time passes, a person gradually ages, vision becomes worse, and eye diseases appear. Some of the worst are cataracts, which affect 95-98% of older people, and glaucoma, which occurs in middle age. This small but extremely informative book brings together for the first time both scientific information about these ailments and recipes for alternative and traditional medicine, as well as recommendations and proprietary techniques for preserving vision and improving eye health. The author sincerely hopes that every reader will be able to find here something truly useful for themselves, something that can help and teach how to cope with the disease and preserve vision.
