Abstract: Vision is the most fundamental of our senses and it is perhaps the greatest tragedy of all when blindness robs us of this modality. Although all parts of the eye are important for perceiving a good image, the most vital layer for vision is the retina. The retina is essentially a piece of brain tissue that gets direct stimulation from the outside world's lights and images. We have tried to present material at the cutting edge of the present knowledge, but in a simple way that is accessible to both expert and non-expert people. [Information of the supplier, modified]
