to ensure that your sunglasses provide at least 98%

Sunglasses is best for you to be comfortable, is a good choice. Although the daily use to determine the standard of the vast majority of sunglasses, some activities may need some extra. For example, if you are buying sports, such as riding a bike, you will benefit from more and more padded weapons and a nose clip, as this will prevent any excessive movement.
Your sunglasses colors is a further consideration, not all colors suit all skin types or under what conditions, you may be wearing glasses. For example, if you are a real bright sunlight, you'll find out, will help the blue lens sharpness, but as an all-around player, you should consider the tinted lenses. Polarized lens sharpness can be improved is especially useful for pilots and fishermen.
