I think they might have told some tale to a medical mind.

Normally, his eyes are blurry like the rest of his fatherly face.

And their color, I think, is blue.

But just then they looked like no eyes I have ever seen.

A cold light on burnished steel is the only simile I can think of--perfect hardness, perfect coldness, lustre without depth! The description is poor, but you may get the idea better if I describe the effect of the look rather than the look itself.
