Is this the most current information?  As I understand it, the engineer knew that his vision was varying from day to day, and could therefore recognize when it was at its poorest state.  Also, as I understand it, the engineer could not disinguish red from green at times.  What I wonder is whether the engineer routinely passed signals while realizing that he could not tell their aspect.  That would be much different than failing to interpret the aspect of signals being passed, but not being aware of the failure.  The latter would be an accident.  The former would be a crime.
