Basics of Visual Optics: A Foundational Optometry Textbook for B.Optom Students | Schematic Eye, Convergence, Emmetropia, Ametropia, Anisometropia and Progressive Lens Design: 1

Basics of Visual Optics is a foundational textbook written specifically as per the Revised B Optom Course Curriculum, designed to help optometry students build a clear, exam-ready understanding of visual optics from first principles. Authored by Ajay Kumar Bhootra and Swarnali Pal, the book moves through 26 chapters across three sections, taking students from the basic science of vision to the applied optics used in everyday clinical practice. Section I lays the foundations - the nature of vision itself, geometric optics of the eye, the schematic eye (including Gullstrand's model and the reduced eye), the eye as an imaging system, its optical constants, and its axes and angles. Section II covers ocular optics and focusing mechanisms in depth: accommodation and presbyopia, convergence, emmetropia and ametropia, astigmatism (including image formation by cylinder and sphero-cylinder lenses), and anisometropia and aniseikonia. Section III turns to refractive correction and applied optics, covering the correction of refractive errors and refractive surgery, and a comprehensive spectacle optics chapter spanning lens power, forms, base curve, thickness, prismatic effect, optical aberrations, lens material and Abbe value, tinted lenses, and bifocal, progressive addition, regressive, anti-fatigue, and myopia-control lens designs. Who This Book Is For: B.Optom Students: a curriculum-aligned foundational text covering the complete Revised B Optom visual optics syllabus in one book. Why This Book Helps: Curriculum-matched from the ground up: written specifically for the Revised B Optom Course Curriculum, not adapted from a general optics or ophthalmology text. Builds concepts in a clear progression: moves systematically from basic vision science through ocular focusing mechanisms to applied spectacle and refractive-correction optics. Covers the full spectacle-optics toolkit: a single detailed chapter spans lens power, aberrations, materials, and every major lens design category (bifocal, progressive, regressive, anti-fatigue, myopia-control). Exam-friendly structure: content organized for straightforward revision of core visual-optics topics ahead of university examinations. Key Features: 26 chapters across 3 sections spanning foundational, ocular, and applied/refractive-correction optics. Dedicated chapter on the schematic eye, including Gullstrand's model and the reduced eye. In-depth coverage of accommodation, presbyopia, convergence, and both emmetropia/ametropia and astigmatism. Comprehensive spectacle optics chapter covering lens forms, aberrations, materials, coatings, and all major multifocal lens designs. Written as per the Revised B Optom Course Curriculum, with a foreword by Kushalendu Goswami.
