This work focuses on the design and application of the Ski-optometer, an instrument aimed at streamlining the processes involved in eye refraction and assessing muscular imbalances in vision. The book serves as a guide for practitioners and those interested in improving efficiency and accuracy in ocular examinations. The opening of the text introduces the reader to the conceptual foundation of the Ski-optometer, explaining how it seeks to enhance the refractionist's practice by simplifying the handling of trial lenses and addressing muscular imbalance—an often neglected but crucial aspect of eye examinations. Woolf discusses the necessity of optimizing time and accuracy in the refraction process and outlines the shortcomings of traditional methods, leading to the development of the Ski-optometer as an automatic trial-case solution. The initial chapters set a technical tone, laying the groundwork for a detailed exploration of the Ski-optometer’s features and its application in various ocular assessments.
