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.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
