It also provides an overview of the optical instruments and procedures that are used to diagnose errors in vision. The book begins by covering the basics of Light and Optics. It then covers Visual Acuity, tests for Potential Vision, and Contrast Sensitivity. The book also looks at Errors of Refraction and Determination of Errors of Refraction. It explains the causes of Asthenopia.Theory and Practice of Optics and Refraction also discusses Corneal Topography or methods of non-invasive analysis corneal surface curvature. It also goes into Keratometry and Aberrometry. The book then focuses on all aspects of Spectacles as corrective instruments for eye defects.
