Paperback. Condizione: New. Print on Demand. This book defines and explains the laws of conjugate foci as they relate to the human eye, and how these principles provide the basis for understanding refraction. The author explores the different optical systems in the eye and their functions and introduces the principal plane, including the principal focus and conjugate foci. The laws of conjugate foci are illustrated through the movements of an object emitting rays, beginning at infinity on the left and going to infinity on the right, exploring different positions of the object and the resulting movements of the conjugate focus. The author also applies these laws to the human eye, explaining the conditions of emmetropia, myopia, and hypermetropia, and additional chapters are dedicated to the conjugate focus in accommodation, ophthalmoscopy, and skiascopy. By examining the conjugate foci formed by the eye's optical systems, this book provides a comprehensive understanding of the principles of refraction.
