Blue light causes haziness and limits how far you can see. Copper HD sunglasses are similar to the original Blue Blockers, except Blue Blockers are more orange in color. We believe Copper HD sunglasses provide a more natural, soothing view compared to Blue Blockers. With Copper HD, you can see the golf ball after a 250 yard drive.
