How does blindness from brain damage differ from blindness from eye damage?
What will be an ideal response?
Someone with cortical blindness loses visual imagery, even in dreams, whereas someone who lost vision by eye damage after at least a few years of sight will continue to have visual imagery and visual dreams, at least for years. Sunlight continues to regulate the sleep-wake cycle of someone with cortical damage, but not someone with damage to both eyes. Also, some people with cortical blindness have blindsight, in which they can indicate the location or other properties of a visual stimulus without consciously perceiving it.
