Solution Approach 2:

The patent applies different conductive coating densities and patterns to different regions of the lens based on local heating requirements. Areas requiring more heat receive higher coating density, while areas needing less heat receive lower density, optimizing energy distribution and consumption.

Inventive Principle:
