Abstract
A goggle lens is coupled with a goggle frame for enclosing a wearer's head, and includes a first lens portion, at least one second lens portion integrally connected with a lower edge of the first lens portion, and a third lens portion integrally formed with and extends upwardly from an upper edge of the first lens portion. A first convex surface of the first lens portion has a first vertical radius of curvature which is different from a second vertical radius of curvature of a second convex surface of the second lens portion, and is different from a third vertical radius of curvature of a third convex surface of the third lens portion so as to provide a wearer with good visual effects.
Claims9
A goggle lens adapted to be coupled with a goggle frame for enclosing a wearer's head, comprising:
- a first lens portion including a first convex surface that is distal to the wearer's face, said first convex surface having a first vertical radius of curvature along a first meridian direction;
- at least one second lens portion integrally connected with a lower edge of said first lens portion, said at least one second lens portion including a second convex surface that is distal to the wearer's face, said second convex surface having a second vertical radius of curvature along a second meridian direction, wherein said second vertical radius of curvature is different from said first vertical radius of curvature;
- and
- a third lens portion integrally formed with and extending upwardly from an upper edge of said first lens portion, said third lens portion including a third convex surface that is distal to the wearer's face, said third convex surface having a third vertical radius of curvature along a third vertical direction, wherein said third vertical radius of curvature is different from said first vertical radius of curvature.
