title: Aging, physiology, and vision.
abstract: This article provides an overview of the normal, physiologic changes in vision that are a part of the aging process. Associated symptoms noted by and worrisome to many patients also are discussed. Clear explanations of the rationale and cause of these concerning complaints reduces anxiety and enables people to function more safely in environments in which visual loss is likely to have a deleterious effect. Likewise, accurate understanding of normal versus pathological vision symptoms assists health care providers, such as nurse practitioners, to better triage, assess, and treat ophthalmic-related problems.
