Our Feather Vision Series Lenses are great for the 3D course and hunting alike. They make for a valuable add-on to your HHA sight. HHA’s proprietary AR coating provides a superior scratch resistance comparable to glass and a super slick surface that repels water completely. A separate oleophobic coating is also added to repel fingerprints, grease, dust, dirt and makes our lenses very easy to clean. These lenses are made using the highest quality optical grade polycarbonate material.
