I usually don't consider myself an extreme person, but a few years ago, as Elul came along, I decided that for one Elul, I could do something that (to me) seemed a bit extreme, the kind of thing that "those" guys do. You all know what I mean - thy guys that take things just too far, etc.
Anyway, I decided that whenever I left super-chareidi areas, I would take my glasses off. Just an extreme Elul thing.
To my surprise, it was liberating! I suddenly just didn't have to battle my eyes, didn't have to fight to avoid looking at things I didn't want to...everything became a blur of shapes, to the point where I could barely tell that a particular shape was a woman!
Unfortunately, while I did end up doing it past Elul, it didn't last as long as it should...but I'm starting to do it again, albeit not on a regular basis. And it just feels great!
I kinda feel like it's a perfect example of "let go and let God," because by taking off your glasses, there is a certain loss of control...
As a side note, the first time I did this recently, I got an almost instant wave and hug from Hashem (in a form that made it clear (to me) that I'd done the right thing) - in the form of an opportunity to do a mitzvah! A half-block after taking off my glasses and slipping them into my pocket, I noticed a frum-woman shaped blob in my blurry vision, about to start dragging a baby carriage up the stairs to an elevated train station. I seized the opportunity for a mitzvah, and helped her with it, and got the bonus of not even having to know what she looked like!
Hashem, you ROCK!
