Amazon - 漸層色太陽眼鏡

I was worried the darker top might look harsh, but the fade is really subtle and blends perfectly with the lighter bottom. The tint level I picked gives just enough shade for bright afternoons without making everything too dark inside the car.

The gradient transition is so smooth, from dark enough on top for bright sun to almost clear at the bottom for reading my phone. They fit comfortably and the tint level I picked is perfect for driving.

I was a little worried the gradient would be too subtle, but the 80% tint option I chose gives a really nice transition from dark at the top to nearly clear at the bottom. The frames are surprisingly lightweight and comfortable for all-day wear.
