What do blind people see?
do they only see black like we do when we close our eyes? or just nothing?
My ex-Mother-in-law was born without retinas and can see shadows or both light and dark. It depends on the individual.
They don't see. They are blind.
complete blackness. lack of impute from the eyes to the brain.
They can't see at all.
They see colorful world with their mind and imagination.
