The Spectre Dry-Fly specialist sunglasses feature lightweight polycarbonate frames and 2mm polycarbonate yellow non-polarised lenses for the ultimate fly and bite detection. When dry fly fishing the solid fly silhouette stands out against the glare of the water while the yellow lens tint takes the sting out of the brightness of the sunlight. If this glare is removed by a polarising lens the dry fly melts into the background colour of the water making it harder to see. This specialist un-polarised sunglass is perfect for dry-fly fishing giving you greater clarity to keep your fly in sidght at all times reducing missed takes.
