Abstract:
1. An insertion tool for the insertion of a contact lens onto a lens wearer's eye, said insertion tool comprising: a housing having a power source and a generated light source, said generated light source being disposed on a forward end of the housing; a plunger attached to the forward end of the housing, the plunger having a distal end, a proximal end defined by a rear wall, an inner cavity, said rear wall having an opening into which the generated light source of the housing projects a beam of light along an axis toward the distal end of the plunger, said rear wall opening having a peripheral boundary through which the beam of light projects, said peripheral boundary defining the dimensions of said beam of light; a lens holder attached to the distal end of said plunger, said lens holder having an opening that allows the beam of light to pass through the plunger and lens holder, said beam of light being visible to a wearer when the lens holder is aligned with the wearer's eye; wherein said plunger is manually compressible creating a suction effect securing a lens to said lens holder; and said generated light source is electrically connected to the proximal end of said plunger, said proximal end being opposite and spaced away from said distal end of said plunger, said beam of light projecting along an axis in the inner cavity that extends from said proximal end of said plunger to said distal end; wherein said plunger is deformable in a direction substantially perpendicular to the axis of the beam of light and wherein said beam of light is not altered by any structure located within the inner cavity; and wherein the entire peripheral boundary of said beam of light is visible within said opening in said lens holder allowing a user to align the insertion tool by tilting the tool until the entire peripheral boundary is visible and centered within the opening in the lens holder.
