All Day Polarised Fishing SunglassesAmber lenses are a good all round colour to improve vision, reduce glare, and help you see into the water more clearly. They also cut blue light (HEV), boost contrast and depth perception, and offer 100% UVA UVB protection. Amber polarised lenses give you clearer vision in mixed and overcast light, helping you read rivers, flats, and near bank water with confidence.
