This is the same question that the students of John Dalton (1766-1844) asked after his death.
Dalton was the first person to describe color blindness as he was profoundly color blind himself. In fact the proper name for green-red color deficient vision "Daltonism" is derived from the name of this chemist and physicist.
A his eyes looked normal in life, his students reasoned that there must be something about them that changed his vision. After his death they removed his eyes. One eye was drained of its fluids so they could be put in a glass vial and peered through. The other group scraped the back of one of the eyeballs to see if the whole eye (aquious humour, vitreous humour, lense etc.) had to be considered in producing the colour blind effect.
Both groups saw no effect on colur transmission.
So his eyes looked normal in life and noramal in the autopsy.
Many years later the cause was determined to be a problem with the retina (a neuro-membrane lining the inside back of the eye) of the eye itself.
