Paperback. Etat : New. Print on Demand. This book delves into the intricacies of artificial lighting, particularly as it pertains to educational settings such as schools and homes. Building on previous research, the author examines the relative effectiveness of various gas and petroleum lamps and their accompanying shades. Through the use of photometry, a method of precisely measuring light intensity, the author reveals both the benefits and drawbacks of each lighting apparatus, providing detailed insights into how these factors impact the well-being of students and individuals engaging in reading and writing tasks. The author demonstrates how lighting conditions can influence the strain on the eyes, linking excessive strain to the development of nearsightedness. By assessing the amount of light produced by different lamps and the distribution of that light across a work surface, the book equips readers with the knowledge necessary to make informed decisions about lighting choices that promote optimal visual health. Ultimately, this book not only provides a comprehensive analysis of artificial lighting but also highlights its significance in shaping the educational and domestic environments in which we live and learn. 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. print-on-demand item. N� de r�f. du vendeur 9780243555321_0
