  • Patent number: 6478422
    Abstract: The present invention includes a pair of glasses to be worn by a shooter using a scoped rifle or pistol where correction is needed by the shooter in order to obtain a clear site picture in the viewing end of the scope. The right lens for a right handed shooter would contain a custom bifocal element for sighting convenience. The left eye lens would not contain this bifocal area but would be clear or prescription for distance as required by the shooter. The far sighted person would want a bifocal similar to their reading glass correction in order for the image on the scope to be clear and focused since the scope is viewed from a distance called eye relief. Properly placed and sized, this bifocal area does not impede the distance viewing of the glasses and thus, the hunter or shooter does not have to put on and take off his glasses constantly while in the field. The left handed shooter would need the shooters bifocal in the left eye and not in right side.
