Sunglasses is good to protect our eyes from the bright sunlight. I have one with power. Although my glasses has transition lens, it is still the best to put the sunglasses on if the sunlight is too bright, especially during driving. Due to the power and thickness of the glass, I only left a few brand choices to choose from. I always want to get a RayBan sunglasses. It looks cool and stylish. It only can become reality if I wear contact lens. I tried that but I always fail from putting the lens into my eyes. After several attempts, I gave up and back to normal glasses.
