Distractions during practice ( Goenka)
You have very strong concentration but your mindfulness is lacking behind. Every time you fix your mind on an area the concentration takes over and because you have strong sensations in the eyes your concentration takes you back to the eyes. 

The solution is to scan faster whereby you increase your mindfulness and not let concentration zoom in. When you have succeeded to prevent going back to the eyes then slowly slow down your scan.

You may have to start to scan as fast as a Xerox machine.
