If we are born with colour blindness , why can’t the brain adapt to the eye? If the baby is told by the parent this is blue and the child sees something else they will learn it as blue right?
In: Biology
There’s different types of colorblindness, but there is a loss of information. When you’re colorblind, parts of your eye are missing and your brain doesn’t receive the same information. Imagine there’s three buckets filled with balls. Different colors have different amounts of balls in each buckets. This is kinda like how we see color (it’s an oversimplification). Bucket 1 sees blue, bucket 2 sees green and bucket 3 sees red. Seeing purple is having (1,0,1) in the buckets. Some types of coloblindness happen because a bucket is missing. So when you look at purple you get (1,0,-).
So if we have something blue (1,0,0), the parent sees (1,0,0) and tells the kid this is blue. In this case the kid also sees (1,0,-) and learns this as blue. But if we have something purple (1,0,1) it’s a bit different. The parent sees (1,0,1) and tells the kid the kid this is purple. But the kid still sees (1,0,-), the same thing as blue. So now the kid has two labels for what is percieved as one color. All learning and adaptation done by the brain is done at higher levels (I believe this actually takes place in the eye, not the brain). If the brain is a computer, this is a broken USB port, not a software butg.
Of course this is a simplification. You don’t pick up on colors quite this directly and you also pick up on the overall brightness (in this example, the purple would look brighter).
My friend has red green colorblindness and can’t make out the difference between red and green. His parents can’t show him a green thing and say this is green and show him a red thing and say this is red. His brain perceives them as the same colors and he can’t see a difference
