I don’t really have a suggestion for them not feeling comfortable. I have days when I can never get them to sit right, and other days where I never notice them. For me, that just seems random whether they’re uncomfortable or not. As for one lense feeling heavier, that makes sense to me. If they just slipped a clear lense in, it might’ve been something similar to the lenses they use on the display glasses, and those are definitely lighter than actual lenses. It seems weird that they wouldn’t have used something weighted, but it makes sense that it’s lighter.
