Author Description

Major revision for 2013-2014! In this major revision, Section 3 has been completely reorganized for easier use! You'll find more real-life clinical examples, many new figures and brand-new learning exercises to help gauge your understanding of the material. This section provides a comprehensive overview of clinical optics, including current applications of optical phenomena such as lasers, spectacles, IOLs and refractive surgery. Presents optics of the human eye; basic concepts of geometric optics; ophthalmic instruments and contact lenses. Vision rehabilitation is also discussed. Upon completion of Section 3, readers should be able to: *Outline the principles of light propagation and image formation and work through some of the fundamental equations that describe or measure such properties as refraction, reflection, magnification and vergence *Define the various types of visual perception and function, including visual acuity, brightness sensitivity, color perception and contrast sensitivity *Explain the optical principles underlying various modalities of refractive correction: spectacles, contact lenses, intraocular lenses and refractive surgery
