I love these. I wear blue light filtering glasses every time I look at a screen, which is all day. I'd been mostly fine with some cheaper ones that I liked the look of but they slip and we're heavy. These don't slip and are very light. I have several pairs and these are far and away the most comfortable and stable. I wanted the transition and was super excited(like way too excited) about it. Unfortunately that bit let me down. They transition slowly and barely. It still helps since my desk is facing a window but they certainly couldn't pass for sunglasses even in the brightest light for a long time. I would still buy another pair because they are cute and comfortable and filter blue light preventing headaches and eye strain so still worth it. I hope they get the transition working better in the future because I will most likely buy these again when I inevitably break these (because I'm clumsy not because of quality, they seem sturdy). EDIT I was wrong they transition fine, I don't know why it seemed like they didn't before but they definitely do and I'm buying another pair bc these rock
