US Patent 7163245 Contact lens insertion tool

An insertion tool of the present invention includes a housing shaped to accommodate a generated light source and a power source. The generated light source is electrically connected to the power source and projects a beam of light along an axis toward a distal end of the housing. The insertion tool also includes a lens holder attached to the distal end of the housing. The lens holder has an opening that allows the beam of light to pass through the housing and lens holder. The beam of light is visible to a wearer when the lens holder is aligned with the wearer's eye. The invention uses the strategy of focusing on a target that can be clearly seen by the user to insert a lens that otherwise can't be seen by the user.
