Colour Blindness with Near Drowning
If someone were to have a near-drowning experience, would it be possible for them to develop colourblindness? Say, lack of oxygen to the brain or if they hit their head on a rock, could there be a possibility of them acquiring colourblindness? If it is possible, what type of colourblindness could they develop? Or would the colours just become muted in a way? Thank you.
