Abstract
Sunglasses with vision directing sections comprise a frame with temples to hold the frame on the wearer's face and lenses in the frame. Each lens is tinted on its front and rear surfaces and one of those surfaces is further coated with a reflecting layer except in the area of the vision directing section. The sunglasses provide highlighted vision through the vision directing sections so that the wearer's vision is directed to that portion of their field of vision. The sunglasses are useful in a variety of activities where it is beneficial to direct attention to a select portion of a person's field of vision or where it is desirable to have a less shaded view through the sunglasses.
