Completely revised and updated, you will benefit from new and rewritten sections on: axial magnification
Jackson Cross Cylinder tests
retinoscopy reflex motions
field of view
the optics of indirect ophthalmoscopy
optical aberrations
diffractive lenses
the Doppler shift
lasers and the similarities and differences of Gaussian laser beams versus the propagation of light from a point source
plus, a new appendix on angles and basic trigonometry.
Although not a matrix optics text, matrices are used extensively in the chapters on spherical systems and off-axis aspects of astigmatism. In particular, the matrix treatment of astigmatism serves as a foundation for the recently developed, much improved statistical techniques that deal with refractive corrections and astigmatism in all its aspects. * Emphasizes conceptual understanding and development of optical intuition * Uses the vergence-dioptric power-wavefront approach * Helpful review for optometry boards and qualifying examinations
