Any type of vision loss (e.g. blindness, blurred vision, double vision, etc.) is a symptom of great concern. Many of the causes are very serious medical conditions. Certain types of vision changes can be a medical emergency where delay can lead to loss of sight (e.g. for causes such as glaucoma, eye injury, retinal detachment) or loss of life (e.g. for causes such as stroke, TIA, etc.).
Vision loss can also be considered as loss of sight that cannot be corrected to a normal level with eyeglasses. The causes of loss of vision are extremely varied and range from conditions affecting the eyes to conditions affecting the visual processing centers in the brain. Impaired vision becomes more common with age. Common causes of vision loss in the elderly include diabetic retinopathy, glaucoma, age-related macular degeneration, and cataracts.
