I've been using the YIMI Photochromic Blue Light Blocking Glasses for a few weeks now, and they've become my go-to eyewear for both indoor and outdoor use. The photochromic feature is a game-changer—transitioning from clear to tinted in sunlight feels like having two pairs of glasses in one.

At my desk job, these glasses help reduce eye strain from staring at screens all day. I noticed less fatigue during long work sessions, though I do wish the blue light blocking was more pronounced—some colors still peek through.

The real magic happens when I step outside. While it takes about a minute for the lenses to fully darken (during which I do squint a bit), the UV protection is excellent once they've adjusted. They're not as dark as dedicated sunglasses, but perfect for casual outdoor use.

Comfort-wise, the lightweight metal frame is great for all-day wear, though the nose pads have a persistent plastic smell that's bothersome up close. The non-spring hinges feel sturdy but might not suit those who prefer flexible temple arms.

The included hard case and cleaning cloth are nice touches that make these travel-friendly. While they may not block blue light as effectively as claimed, their dual functionality makes them worth considering if you want one pair of glasses that adapts to different lighting conditions throughout your day.
