Eye Examination
The American Optometric Society (www.aoa.org) states that periodic eye and vision examinations are an important part of preventive health care because 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 medical eye examination may include, but is not limited to, the following tests:
- Patient history to determine any symptoms that may be affecting your vision.
- Visual acuity to evaluate how clearly each eye is seeing.
- Preliminary testing to evaluate specific aspects of visual function and eye health, such as depth perception, color vision, peripheral vision, and the way your pupils respond to light.
- Keratometry to measure the curvature of your cornea.
- Refraction to determine the appropriate lens power to compensate for your refractive error (nearsightedness, farsightedness, or astigmatism).
- Eye movement testing to determine how well the eyes focus, move and work together.
- Eye health evaluation, which includes an external and internal examination of the eye.
