Excellent value for the money. They give an adjustment screw driver, cloth case,and life time warranty. They fit and look great. I’m very happy with them.
I use them in car when driving definitely saves on eye strain.I was not previously a BluBlocker user and these glasses really take some getting used to. The deep amber tint really changes perceived colors. But blue is such a strong component of sunlight, there are a lot of advantages to filtering it out compared to neutral sunglasses. For one thing, the scene remains relatively bright because your eyes are still getting most of the rest of the spectrum. But without the intense blues it’s not actually too much light for your eye. This means that in many conditions you really will see better. The biggest disadvantage in my opinion is that the world is just not as beautiful without the blue.
