In Introduction to Visual Optics: A Light Approach, Samantha Strong brings fresh life to a traditionally dense topic, making optics accessible, engaging, and even enjoyable. With a conversational tone and clear organisation, Strong guides readers through complex concepts in a way that feels inviting rather than intimidating.
Her approach makes this book a fantastic resource for students, optometry professionals, and ophthalmic healthcare professionals looking to deepen their understanding of optical principles.
The book is structured into five main sections, gradually moving from foundational theories to practical applications and hands-on experiments:
- Section 1: ‘Geometric and Basic Optics’ introduces essential principles like the basics of light and colour, vergence and refraction, thin and thick lenses, spherical and cylindrical lenses related to the eye, as well as topics on reflection, ray tracing, dispersion, chromatic aberration, and prisms. This section provides a solid grounding for the basics of optics, which can be helpful for those needing a refresher on foundational concepts.
- Section 2: ‘Physical Optics’ covers the physical properties of light, such as superposition, interference, and diffraction. These concepts give readers a deeper understanding of light’s behaviour, complementing the material in the first section.
- Section 3: ‘Clinical Applications’ bridges theory and clinical practice. This section covers focimetry, photometry, optical instruments and low vision aids, polarisation, imaging the eye and measuring refractive errors, wavefront aberrations, adaptive optics, and optical coherence tomography. For those in clinical roles, this section provides essential insights into the practical applications of optical science.
- Section 4: ‘Experiments to Do at Home’ includes hands-on experiments that allow readers to apply the scientific principles discussed in earlier chapters. Projects such as creating a camera obscura, simulating a blue sky at home, and even measuring the speed of light provide an engaging way to reinforce understanding. Although healthcare workers may not always have the time to explore these activities, it’s still enjoyable to have this option for a hands-on way to engage with the material.
- Section 5: ‘Question Answers’ offers answers to practice questions and quizzes found throughout the book, allowing readers to assess their knowledge and track progress, reinforcing key concepts as they study.
In addition to the well-organised content, Strong’s thoughtful design choices enhance readability and comprehension. Key terms are highlighted in bold, equations are colour-coded, and the book is filled with high-quality diagrams. Each chapter begins with an outline of topics and clear learning objectives, helping readers set goals and focus on specific skills as they progress. Furthermore, demo questions and chapter-end quizzes reinforce learning, allowing readers to apply their knowledge in real time.
One of the book’s standout features is its digital accessibility. Readers can access a read-aloud feature, customisable layouts, a searchable glossary, and multicoloured highlighting options on any device, allowing them to study on the go and tailor the material to their preferred learning styles. This modern approach sets Introduction to Visual Optics apart from traditional textbooks, enhancing its appeal as a versatile, accessible resource.
Overall, Introduction to Visual Optics: A Light Approach is a remarkable resource that reflects Strong’s commitment to making optics both comprehensive and accessible. With its thoughtful explanations, hands-on tools, and innovative digital features, this book truly transforms a traditionally dry topic. I give it five out of five stars for bringing a fresh, modern approach to the field of visual optics.
