In "The Rocking Horse Winner," the writer describes Paul's eyes. What do they tell us about Paul?

The first description is "The boy watched her with unsure eyes" which indicates that he is thoughtful, ponderous.  Most of the descriptions are:  "His eyes had a strange glare", "big blue eyes blazing with a sort of madness", "His eyes blazed", "a blue glare...his blue eyes still flaring", "big, hot, blue eyes", "his eyes were blue fire...with eyes blazing"  All descriptions related to him on his horse, thinking or talking about winning money, or being at the races reflect a hot, burning obsession that is taking over him.  Blaze, glare, flare, fire:  strong words, consuming, and destructive, perhaps foreshadowing the unpleasant result of his quest. 

When his uncle or mom suggests he stop, the descriptions change:  "uncanny blue eyes" (creepy or unique) and "The boy watched him with big blue eyes, that had an uncanny cold fire in them".  The fire changes to cold-frightening, but a fire nonetheless.  Eventually, he was "wild-eyed and strange," adding even more of an element of being out of control.  Before he dies, there is a change:  "his eyes were like blue stones".  All fire, passion, and life is gone; he is left as cold and empty as a stone.  His obession has burned the life out of him.  The eyes are a very efficient way to relay information about the inner mindset of a character, and Lawrence does the well, tracking the tragedy of Paul.
