Скачать или смотреть Inside the Eye: How Photoreceptors in the Retina Produce Vision

Join Dr. Jeffery A. Jones for an exploration into the fascinating world of vision. We uncover the complex processes by which our eyes convert light into the vivid imagery we see. We explore the components of the eye and their roles in visual perception, from the lens to the remarkable function of photoreceptors.
