Hmmm... Well, this is an assumption, but when you learn songs off a cd or however you practice just put the radio in front of you, and then stare at the radio while you play. Honestly the more you practice in general, the more you will get comfortable with the fretboard. You will start to develop muscle memory. Honestly most guys that don't look down (I still sneak peaks time to time

) are guys that have either been playing for a long time, or guys with excellent practice techniques that have paid off. My technical advice would be to develop a left hand technique where you have your fingers slightly fanned with the tips pointing at the frets, with your thumb in the middle of the back of the neck (not pressing too hard) and run some scales keeping your hand in that position. Pretty soon you will know what finger you need to press and that is what will get your eyes up to lock in with the laaaadies (or the dudes... whatever your pref.

)
