1. A power-saving method for efficiently heating an eye-shield apparatus adapted for use with a thin-film heater powered by a power source to prevent fogging of the eye-shield comprising the steps of:
activating the heater from an off power level to a max power level on the eye-shield apparatus;
continuing heating at the max power level for a first duration of time;
lessening power supplied to the heater after the first duration of time to an intermediate power level between the off power level and the max power level;
continuing heating at the intermediate power level for a second duration of time; and
setting the power to the off power level after the second duration of time.
