What To Think About

• Eye charts that use pictures or symbols (such as an E chart) may be needed to test children or people who cannot read. Vision tests are also available for babies and young children.
• A complete eye and vision evaluation also includes a physical examination of the structures inside the eye. For more information, see the topic Ophthalmoscopy.
• A test to screen for increased intraocular pressure (IOP), which increases your risk for glaucoma, is often part of a routine eye exam. It also is used to monitor treatment for glaucoma. Tonometry can be used to determine whether a medicine is keeping your IOP below a set target pressure determined by your doctor. For more information, see the topic Tonometry.
• Home tests for near vision in adults and distance vision in children are available. These tests should not replace a thorough eye examination by a health professional.
