Has anyone removed the headlight LENS, only?

OK, my headlights are murky like everyone's, so I ordered more.  The lens cover alone was cheaper than the entire assembly.  One review said it worked fine, but he wouldn't do it again.  Have any of you removed the headlight assembly and then removed the clear lens for replacement?  Any tips on getting it apart?  It's pretty tight and I'm thinking it's glued as well as snapped.  Anyone?

What year?

99-04 are sealed/glued.

2009.  It appears to be glued also.  I found some obscure references to using an oven, but wanted to see if anyone here has some direct experience doing it.
