I have tried many clip on sunglasses and these are by far my favourite. They are lightweight but durable. My glasses are easy to put on and take off, but stay on securely once attached. The visual acuity is good and the toning is perfect for me. The app does not block my view. They look a little weird and the clamp and release mechanism is a visible protrusion above the bridge of your glasses that people will notice and might look a little nerdy but I've always been the shape guy so who cares? A minor issue is that the little soft rubber/silicone grommets that cushion the pinch points tend to fall off and get lost over time.
