Okay, so I snagged these YIMI photochromic glasses after my cat (again) sat on my last pair. First impression? They give off major '70s detective vibes – my partner said I look like a hip librarian. The TR90 frame is crazy lightweight, and the spring hinges actually fit my weirdly narrow face without squeezing my temples.

The photochromic feature is... interesting. They don't get super dark – more like a light gray tint when I'm outside. Fine for cloudy days but kinda wimpy in direct sunlight. Still beats carrying separate prescription sunglasses though!

Durability seems decent so far? I've dropped them twice (oops) and they survived, unlike my last $400 pair that shattered from a 2-foot fall. The lenses are thicker than premium options (I'm at -4.25), but honestly the retro chunky look works.

Biggest gripe: The left hinge started creaking after 3 weeks of daily wear. Not broken yet, but I'm side-eyeing it suspiciously. For the price though? Worth having as backup glasses stashed in my car/office/purse – because we all know glasses have a habit of going AWOL when you need them most.
