Sapco, we are completely at cross purposes.
Of course "peripheral vision" is essential to landing.
My point is that what we call "peripheral vision" is actually a combination of poor eye and excellent brain. If you literally force yourself to fixate on one single point you will have extremely poor "peripheral vision". The more natural human behaviour is to flick your eyes around what you are looking at. Which is what I suggested.
Here is another fun example of the brain's visual system at work: get somebody to throw something (soft) at you, so you can catch it. Close your eyes while it is in mid-air. Odds are you will still catch it... Now, before you tried this, how did you think you caught things?
And no, I am not suggesting you close your eyes while landing...
