Low vision is a term describing a level of vision below normal that cannot be corrected with conventional glasses.
Low vision interferes with the performance of activities of daily living such as reading or driving.
The level of visual loss may range from mildly reduced vision to legal blindness. The symptoms described above may not necessarily mean that you have low vision. However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam. Your eye doctor can tell the difference between normal changes which are common with age and changes caused by eye disease. Although low vision can occur at any stage in life, it primarily affects the elderly.
