The brain's flexibility allows for adaptation to visual impairments from "summary" of The Mind's Eye by Oliver Sacks
The brain is a remarkable organ, capable of adapting and compensating for a multitude of challenges and changes, including visual impairments. When a person experiences a loss of vision, whether sudden or gradual, the brain has the unique ability to reorganize and rewire itself in response. This process, known as neuroplasticity, enables individuals to make use of the remaining visual information available to them, as well as develop alternative strategies for navigating the world. One example of the brain's flexibility in the face of visual impairments is the phenomenon of blindsight. In cases where a person has damage to the visual cortex, rendering them blind in a specific area of their visual field, they may still be able to respond to stimuli presented in that area without consciously seeing them. This is because other parts of the brain, such as the superior colliculus, are able to process visual information and guide actions in the absence of con...
