Abstract
A visor for a helmet includes a lens having a top edge that slopes downward from a top center point to first right and left curve points, at the first curve points the top edge begins to slope more aggressively toward second right and left curve points, and more aggressively toward right and left side edge points. A plane of sight along the vertical extent of the lens is displaced above the plane intersecting the side edge points. The lens has a thickness defined between an inner concave surface and an outer convex surface; the inner and outer surfaces having different radii of curvatures. The lens tapers from the center toward the outer edges.
