I went to the optometrist today, since lately my eyes have been bugging me, and as a nerd I am constantly craving some form of objectivity in whatever "problem space" I currently sit.

At some point the doctor looks up from her notepad and asks:

"Is your night vision different?"

I somewhat froze, since I have no good answer for that.  What does that even mean?  I always assumed I was seeing the night, but how do I know that even though I think I'm seeing just Night, I'm actually seeing the Night, but *wrong*.

This frustrates me, because I'm used to solving problems in computer land.  I can reset, pause, adjust, and dissect a problem.  If I had it my way I would be able to start flipping out my eyes for someone else's carefully taking notes, reseting day / night cycles so I could quickly test night vision, or distance, or different computer screens.

Solving problems like this is what makes programming so amazing, and realizing you are able to is a Transformative moment in your career.

But I can't.  I'm stuck with this murky subjectivity that I have to pretend is objectivity, and limp to a solution.

How do other people deal with this?
