Low Vision

Do you have low vision? Do you know someone with low vision? One out of every five people who live into their eighties will encounter vision loss. Some may grow up with healthy vision and then experience vision loss from macular degeneration, glaucoma, or some other eye disease later in life. Others may be born with an inherited or congenital condition that results in low vision such as albinism or retinopathy of prematurity. Most people with vision loss have useful remaining vision; we call it low vision. But what can they see? What is the impact of low vision on their daily lives? Put it simply, what's it like to live with low vision?Low vision is any form of vision impairment, not correctable by glasses or contacts, resulting from eye disease or injury. Low vision is a broad spectrum lying between total blindness and normal vision. The number of people with low vision is rising rapidly as our population ages, with conservative estimates ranging upward from seven million in the United States to hundreds of millions worldwide. Despite its high prevalence, there is little understanding of low vision among the general public and even in the medical community. Gordon Legge is a leading vision scientist who has devoted more than forty years to research on low vision. He has low vision himself, providing him with a unique perspective on the science and its implications. In the book, he describes the diverse nature of low vision, how it is measured and characterized, and its impact on daily experience. By understanding the science behind these experiences, we will all better understand the challenges and possibilities of life with low vision.
