The concept of critical periods suggests that there are specific times during development when the brain is particularly receptive to certain types of learning or sensory information. In the case of vision, if the visual system is not used during these critical periods, typically early in life, it may never develop the ability to process visual information properly, even if vision is restored later. This is why adults who have been blind since birth and then gain sight often struggle to interpret visual information fully.
