Let me tell you about my experience with these Cyxus photochromic glasses. First off, the transition feature is seriously impressive. I wore them while working on my laptop indoors (hello, blue light protection!), then stepped outside - boom! The lenses darkened smoothly within seconds. No more squinting in sunlight!

The included UV test kit is a nice touch. I played with it like a kid - watching the test paper change color under UV light was oddly satisfying. Confirmed the glasses do block UV rays as promised.

Now about comfort: They're super lightweight, which I mostly love. But heads up if you're active - they feel a bit delicate. I almost sat on mine once (oops!) and had a mini heart attack.

The blue light blocking is legit. After long work sessions, my eyes feel noticeably less strained compared to when I wear regular glasses.

One small gripe? The fit runs tight. My big head struggled a bit at first, but they've loosened up slightly with wear.

Overall? These are my new daily drivers - perfect for bouncing between screen time and sunshine without switching eyewear. Just maybe don't drop them!
