Amber lenses enhance vision by blocking the somewhat hazy, blue end of the color spectrum, which results in greater contrast and improved depth perception. Wearers report crisper vision and increased ability to discern shapes, too, especially against green and blue backgrounds. They aid in discerning fish and underwater structures while sight-fishing in relatively shallow water. This is a good choice if you're going to be out in low-light conditions or on a day with changing weather patterns.
