TY - CHAP M1 - Book, Section TI - Chapter 21. Optics & Refraction A1 - Riordan-Eva, Paul A2 - Riordan-Eva, Paul A2 - Cunningham, Emmett T. Y1 - 2011 N1 - T2 - Vaughan & Asbury's General Ophthalmology, 18e AB - The correct interpretation of visual information depends on the eye's ability to focus incoming rays of light on the retina. An understanding of this process and how it is influenced by normal variations or ocular disease is essential to the successful use of any optical aid, for example, glasses, contact lenses, intraocular lenses, or low-vision aids. To achieve this understanding, it is necessary to master the concepts of geometric optics, which define the effect on light rays as they pass through different surfaces and media.
