Plastic eyeglass warming units designed to heat plastic eyeglass frames softening the material to allow the insertion or adjustment of lenses using hot air. These warmers typically consist of a unit including an electric heat source that provides heat to the frames using hot air (i.e., hot air warmers), a fan to facilitate heating, and may also include a heat distributor to focus the heat in specific areas of the frame. Hot air warming units are usually temperature regulated in a range typically from 70 to 150 degrees Celsius (158 to 300 degrees Fahrenheit); they also include temperature resistant holders to attach the frames during the procedure.
