Refraction and muscular imbalance, as simplified through the use of the ski-optometer

"Refraction and Muscular Imbalance, as Simplified Through the Use of the Ski-optometer" by Daniel Woolf is an exploration into an early 20th-century device designed to make eye exams more precise and efficient. The book presents the Ski-optometer as a solution to the challenges of traditional vision testing, aiming to streamline the way refractionists work with lenses and evaluate muscle imbalances in the eyes. Woolf highlights the importance of both speed and accuracy in eye examinations, positioning the Ski-optometer as an innovative tool to improve the process of diagnosing vision problems. The book starts by explaining the basic ideas behind the Ski-optometer and how it can help practitioners move away from older, more cumbersome methods, promising a step forward in how eyes are tested.
