Eye Lens and Refractive Errors

Refractive error is the result of the eye's shape improperly bending light, which causes a blurry image. Surgery (like LASIK) can also be used to treat some refractive diseases. Corrective lenses like eyeglasses or contact lenses are frequently used to treat refractive disorders. During a typical eye exam, an eye care practitioner can identify a refractive mistake. In order to maximise a patient's vision, testing typically involves having the patient read a vision chart while using a variety of lenses. Rarely are specialised imaging or other tests required.
