The changes that occur with aging can lead to problems with mobility (ability to move around), such as unsteadiness while walking, difficulty getting in and out of a chair, or falls. Muscle weakness, joint problems, pain, disease, and neurological (brain and nervous system) difficulties can all contribute to mobility problems. Sometimes several mild problems occur at one time and combine to seriously affect mobility.

The number one mobility problem that older people experience is falls. Falls result in broken bones, bruises, and fear of falling. If a hip is fractured, canes, walkers, or wheelchairs might be needed permanently. Falls are a major cause of injury and death, so prevention is important.

Treatment options include separate pairs of glasses for distant and near viewing tasks, prisms and vision rehabilitation therapy.
