(ii) The ameliorative effects of the mitigating measures of ordinary eyeglasses or contact lenses shall be considered in determining whether an impairment substantially limits a major life activity. (iii) As used in this subparagraph— (I) the term “ordinary eyeglasses or contact lenses” means lenses that are intended to fully correct visual acuity or eliminate refractive error; and (II) the term “low-vision devices” means devices that magnify, enhance, or otherwise augment a visual image.
