Abstract: The present invention teaches an accessory to a laryngoscope, which may be retrofitted thereto or integrated on a new laryngoscope as original equipment, having at least one fastener allowing attachment to the barrel of a standard laryngoscope, a rail secured to the barrel of the laryngoscope by the fastener, and a lens slide seated on the rail and traveling on thereon parallel to the barrel. On the lens slide, a lens frame mounts a progressive magnification lens, that is, a single optical element lens having multiple magnification powers when viewed through different portions (such as a bi-focal lens). A lens pivot mounted on the lens slide holds the lens frame, so that the lens may be adjusted in angle (and thus distance in the direction perpendicular to the rail).
