Section 3 of the Academy's Basic and Clinical Science Course™ (BCSC®) provides a comprehensive overview of clinical optics, including current applications of optical phenomena such as lasers, spectacles, IOLs, and refractive surgery. A chapter on vision rehabilitation addresses the wide range of vision rehabilitation interventions: smartphone accessibility features and apps, electronic magnification devices, audio devices, and various optical devices.

A chief ray is the ray from an off-axis object point which passes through the center of the aperture stop of an optical system. The chief ray enters the optical system along a line directed towards the midpoint of the entrance pupil, and leaves the system along a line passing through the center of the exit pupil. To measure the angle between the optical axis and the chief ray on the image side the following method is used: The lens under test is illuminated by the collimator at different angles corresponding to the object sided chief ray angles. The detector head is moved to the image field position at which the lens focuses the image. Now the detector head is moved towards the lens in small steps while the software registers the lateral movement of the focused spot. From these lateral movements the CRA is calculated. At Optikos, chief ray angle (CRA) is measured by our OPTEST™ MTF Testing System and LensCheck™ VIS. For more information, click on the images below.

Beginning with the 2013–2014 edition, the Academy and the European Board of Ophthalmology (EBO) have partnered to make the BCSC the standard text for all European ophthalmology training programs. The EBO now recommends the BCSC as the primary educational resource for European trainees and ophthalmologists studying for the annual EBO Diploma Exam.

The American Academy of Ophthalmology designates this enduring material for a maximum of 15 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

CME InformationThe American Academy of Ophthalmology is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians.

Each of the 13 volumes includes up-to-date clinical knowledge, concise text, tables, photos and illustrations, multimedia, self-assessment questions with answers, and opportunities for earning AMA PRA Category 1 Credit™.

This section of the BCSC begins with a Quick-Start Guide, which includes an extensive discussion on retinoscopy. The Quick-Start Guide includes seven Try It Yourself! exercises on Hand Neutralization of Spherical and Cylindrical Lenses, Making a Practice Eye, and Detection of Astigmatism.

Nine videos (sample) to increase your understanding of human eye optics, basic concepts of geometric optics, ophthalmic instruments, and contact lenses. An animation video demonstrates a circularly polarized electromagnetic wave. Plus, a dynamic illustration allows modification of "live" drawings to experience the effects of changes in the positions of source objects and focal points. Both print and eBook users have access to the videos and activities.

About the BCSCThe Academy’s Basic and Clinical Science Course™ is ophthalmology’s definitive source of clinical information. Practicing ophthalmologists and residents worldwide use the BCSC® to ensure the highest-quality patient care.
