"Shaping the Next Generation" helps parents grasp God's vision for their children and design an intentional character-building strategy that really works.

This book describes the optical structure and optical properties of the human eye. It will be useful to those who have an interest in vision, such as optometrists, ophthalmologists, vision scientists, optical physicists and students of visual optics. An understanding of the optics of the human eye is particularly important to designers of ophthalmic diagnostic equipment and visual optical systems such as telescopes.

This book describes the optical structure and optical properties of the human eye. For ease of reference, the most commonly useful topics are at the beginning and topics with narrower appeal are placed towards the end. The book is divided into five sections, covering:


Basic optical structure of the eye, including the refracting components, the pupil, axes, and simple models of the eye


Image formation and refraction of the eye, including refractive errors, measurement, and correction


Interactions between light and the eye, considering transmission, reflection, and scatter in the media...
