Periodic eye and vision examinations are an essential part of preventive health care. Many eye and vision problems have no obvious signs or symptoms. As a result, individuals are often unaware that problems exist.
Early diagnosis and treatment of eye and vision problems are important for maintaining good vision and eye health, and when possible, preventing vision loss. A comprehensive adult eye and vision examination may include, but is not limited to, the following tests:
- Patient History: to determine vision difficulties experienced by the patient that may limit their daily activities and other general health concerns affecting vision.
- Visual Acuity Measurement: to determine to what extent a cataract may be limiting clear vision at distance and near.
- Refraction: to determine the need for changes in an eyeglass or contact lens prescription.
- Evaluation of the Lens: (under high magnification and illumination) to determine the extent and location of any cataracts.
- Evaluation of the Retina: the back of the eye through a dilated pupil.
- Eye Pressure Measurement: the pressure within the eye.
- Supplemental Testing: for color vision and glare sensitivity. Individual patient signs and symptoms, along with the professional judgment of the doctor, may significantly influence the testing done.
