Move over Ray-Ban, there is a new top contender in the ring and they are going to knock you out. Having spent many decades using a variety of different name brand sunglasses and growing annoyed, when they would fail their promises, I searched for best sunglasses. After skimming through the regular names, I saw one that was different. It was Gresso. I decided for the price to give them a shot. I had paid more in the past for less. I love them. No other brand for me. Lightweight, bendable, strong, with protection from UV rays. The tint wasn't dark nor too light. You can read with them on and they reduce the glare from the phone screen or Kindle.
