I've only used the yellow lenses and only for about 2 hours so far. I use these for night tennis. The soft case is fine. Do note that the lenses do not fit in the soft case with the frames and whichever lenses you have installed. There is a soft divider to insert the three extra lenses into. They don't fit well at all! This divider then goes into a drawstring bag to help provide further protection. I have no idea why they would not have just designed a single case for the frames and extra lenses to fit into.
While the yellow lenses provide great contrast due to filtering blue light, things aren't as sharp through the lens compared to not using any glasses at all. However, overall, it's much better for my purpose than not using glasses. I did, however, have a strange experience. I felt that the depth perception was slightly altered. Though, I did read a scientific article that said that yellow lenses don't affect it. I'll try them again soon to form a better opinion.
Note: mine were made in Taiwan (whereas others said in China) so maybe they have a new factory making these.
Edited to Add: These were very scratchy on my nose. I looked at the nose piece but it is not adjustable. What I realized is that it's actually the lens that was resting on my nose, not the rubber nose piece. Very poor design there. If shooting, perhaps it's fine but with tennis, I'm moving around and bouncing a lot so there's rubbing. (I will add, though, that I never felt that they would fall off my face or even move out of position so that was very good.)
