George, who is 48 years old, recently had his sight restored after 45 years of blindness. After the operation, he could associate people with their distinct features (e. g., hair color), but could not recognize their faces. He was also not good at judging the size of objects when their distance from him changed. His case suggests that:

He is suffering from Colour blindness and partial memory loss

Explanation:

Colour blidness as the name suggest is the medical state whereby an individual would be unable to recognize the colour of any given object or something as a result of the deficiency in his eyes processing the image. A normal eyes could be able to filter all the colours of an image which it sees and tell which one is which when called upon to do so.

For George to be able to recognize people based on distinct featurelike hair colour shows that he is suffering from colour blidness while the inability not to regonize their face is as a result of partial memory loss caused by temporal loss of sight over the past 45years. He would recover from the partial memory loss as his eyes tries to adjust to the faces and things he sees.
