Accommodative Dysfunction is a term used to describe when a person has difficulty with their focusing system, due to reasons other than natural aging changes. Stress, certain medications, and prolonged reading and computer work can all result in AD. Signs and symptoms of AD include blurry near vision, intermittent blurry distance vision, headaches, and eye strain. A comprehensive eye exam can aid in diagnosing this condition and treatment is often obtained with reading glasses for near vision tasks.
