Optics, Retinoscopy and Refractometry

Combining the topics of optics, retinoscopy and refractometry, this text aims to allow the reader to better measure the patient's refractive error. The optics section discusses light, mirrors, lenses and physiologic optics. A discussion of refractometry and retinoscopy follows.

Combining the topics of optics, retinoscopy and refractometry, this text aims to allow the reader to better measure the patient's refractive error. The optics section discusses light, mirrors, lenses and physiologic optics. The following discussion of refractometry and retinoscopy covers equipment, practical applications and trouble-shooting. The appendix contains data on the metric system, units of measurement and metric conversions.
