The human eye is an incredibly complex organ, it acts like a camera to collect and focus light and changes this light into an electrical signals that the brain then reads to form images. Instead of using film, the eye has specialized components such as the retina that detects light and process it using many types of neurons. The eye is so complex that its origin has long been a hot topic of debate and is often used to defend a creationist point of view, they say the eye is too complex to have evolved

space. Human experience in the space is emphasized and regarded as important as mental map, which is more real and concrete. Limitations: The approaches relying on 2D images fail to fully express the multi-dimensional information perceived in human’s eyes and brain from the dynamic environment, which is much more complicated than simple images and will be combined and filtered by personal experiences and cultural background. All in all, unilateral visual perception cannot fully reflect a comprehensive

optic nerve. The axons of these ganglion neurons are what form the optic nerve. Finally the information is transferred from the optic nerve to the primary visual cortex, which is a part of the brain. The retina is considered the neuroprocessor of the eye and is responsible for the recognition of images. The article continues next stating that there are many different groups of researchers who are creating types of implants to possibly help the vision of patients with retinas that are degenerating.
