About this Item

Print on Demand. This book delves into the field of ophthalmic optics, with a focus on understanding spectacle lenses, their designs, and the concepts behind their use. The author, an established authority in optical science, takes readers through the journey of spectacle lens evolution, from the earliest single-glass designs to modern advancements in aspheric and multifocal lenses. At the core of the book is the exploration of how spectacle lenses interact with ametropic eyes, explaining the principles of correcting nearsightedness, farsightedness, and astigmatism. Diagrams and illustrations help visualize the optical concepts, making them accessible to both professionals and laypeople with an interest in the science of vision correction. Ultimately, this book provides a comprehensive understanding of the role of spectacle lenses in improving visual clarity and enhancing the quality of life for those with refractive errors. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.

About this title

Synopsis

See how lenses shape sight and why glasses work for everyday vision.

In Eyes and Spectacles, McVon Rohr explains the eye as a fixed optical system and shows how different lenses adjust focus and direction to correct ametropia. The book blends clear explanations with practical illustrations to help both prescribers and makers of spectacles.

This edition emphasizes accessibility: it avoids heavy formulas where possible and uses illustrations to illuminate how lenses and frames interact with the eye. It covers the range of topics from how cornea, lens, and vitreous interact to form a clear image, to the ways lenses can be shaped to correct myopia, hypermetropia, and astigmatism. A final section surveys spectacle frames, including pince-nez and lorgnettes, with practical notes on selecting and fitting.

• Learn how the eye focuses light, what goes wrong in common vision problems, and how glasses fix it
• See how different lens shapes and placements affect image direction and perceived space
• Understand the role of frames and accessories in comfort and vision aid
• Get insight into the historical and practical context of lens design and fitting

Ideal for readers of vision science, optical students, and professionals who prescribe or manufacture lenses, as well as anyone curious about how glasses improve daily sight.
