These glasses are perfect for clay shooting and shooting games. The purple-tinted lenses enhance the orange color of the target (clay) when the background is green, such as mountains, while reducing the green. The metal frame can be bent to fit your own settings. I bought these but never used them, so I'm selling them. - Brand: BERETTA - Color: Purple - Accessories: Case, drawstring bag - Design: For clay shooting - Frame Material: Metal - Lens Shape: Curved lens
