Seeing Eye to Eye: Vision: How it Works and What Can Go Wrong by John E. Dowling and Joseph L. Dowling

摘要

Vision is organized along the visual pathways that our brain uses to form images. The Dowlings begin with a neat description of how we see: Vision occurs when rays of light are captured by the photoreceptor cells of the retina that line the back of the eye. This requires a transparent window into the eye and amechanism for bringing the rays of light to a focus on the photoreceptors. Two remarkable structures, the cornea and lens, serve to accomplish this.
