Visual impairment can arise from how the brain processes what the eyes see, not just from the eyes themselves. When vision loss comes from injury to brain areas that interpret visual information, the eyes may be structurally normal, but the processing behind sight is impaired. This is described by Cortical Visual Impairment: a brain-based difficulty in making sense of visual input, which can persist even when eye structure appears healthy. People with CVI may struggle with interpreting complex scenes, recognizing objects or faces, or maintaining attention to visual stimuli, despite having functional eyes.

Macular Degeneration affects the retina, specifically the central part used for sharp vision, and is an eye-origin issue rather than a brain processing problem. The vitreous humor is the gel inside the eye; issues here influence vision as an eye component, not brain processing. Glaucoma involves the optic nerve and is typically linked to eye factors like pressure; its effects come from the eye/nerve pathway rather than brain processing of visual information.
