i find on my prodigys it's also more comfortable to wear them low when it comes to vision, because the bridge of the nose goes up really high and sometimes impede's my plain of view - when i look either slightly left or slightly right, one of my eyes focuses on the plastic where the lens clips down into - so sometimes i wear em low to eliminate that, but its really uncomfortable on the face. it seems the padding is made to fit snug in a certain position, and that position is not 'sagged'
