  • IMPROVED READING EYEGLASSES
    Publication number: 20070035695

The region is preferably centered below a horizontal on the lenses. Thus, a wedge shape is created. The thicker portion of the wedge is oriented toward the upper and inner side of the lenses, thus allowing the user to view close objects with decreased strain on the eyes.
