Single-Vision lenses sharpen your focus whilst taking aim and shooting. Bifocal lenses sharpen your focus on both nearby and far away objects.
Benefits of Bifocal Lenses
Target shooting competitors benefit from a second lens on the non-shooting eye, allowing clear focus when adjusting sights and marking scores.
Clay & Game Shooters benefit from a small region at the bottom of the lens which allows clear focus when re-loading and marking scores.
