  • Patent number: 5790226
    Abstract: The present invention includes a pair of glasses to be worn by a golfer where only one of the lenses contains a reconfigured bifocal lens, i.e. bifocal element. The placement of the bifocal element may be determined by the writing hand of the wearer or may be determined by whether the wearer has a right-handed golf swing or a left-handed golf swing, depending upon the preference of the wearer. In an alternative embodiment, the bifocal element may be placed in both lenses provided that the near vision segment is positioned in the upper outermost temporal portion of the lenses.
