CAL Anti-slip Clip-on Sportbril op sterkte

The clip-on mechanism is surprisingly secure, and the 53mm lens width covers my regular frames perfectly without any gaps. I've been wearing them during my morning runs and they haven't budged once.

At 14 grams, I barely notice they're on, and the acetate frame holds its shape nicely even after being tossed in my gym bag daily. The clip-on flips up and down smoothly without ever loosening, which is exactly what I needed for cycling between indoor and outdoor lighting.

The clip-on mechanism feels rock-solid over my regular frames, and the 14-gram acetate build is so light I forget they're on during a full round of golf. The rectangular lenses sit perfectly without fogging up on my morning runs. Exactly what I needed for sunny commutes.
