That Zennioptical article was really good. Super informative and yet so concise, I wish I could write like that. Surely shouldn't have any doubts after reading such an epic, really. Anyway, I've been wearing anti-glare progressive glasses for 3 years now because it's a sedentary desk job (I'm hoping to change, soon). I recall my ophthalmologist reciting these very words after my Lasik eye surgery for maximum correction- "the best part about your eyes is that they have the adaptability to adjust themselves provided they're trained in the right manner but everyone is too busy staring at computer screens all day". The irony was he was wearing anti-glares and seated in front of a Mac. These guys have got a lot of wisdom and I'd clear all my doubts at the eye clinic instead of spending more hours in front of bright "retinal-display" screens.
