Plastic eyeglass warming units designed to heat plastic eyeglass frames softening the material to allow the insertion or adjustment of lenses using a heated pan. These warmers typically consist of a unit including an electric heat source to provide heat to the frames through a usually recessed and sealed hot pan covered with glass beads or salt to transmit the heat to the frames. Heated pan eyeglass frame air warming units are usually temperature regulated in a range typically from 70 to 150 degrees Celsius (158 to 300 degrees Fahrenheit); they may also include temperature resistant holders to attach the frames during the procedure.
