Customized Progressive Lens Design via Eye Movement Tracking

The patent applies local quality by creating customized progressive lens designs tailored to each wearer's specific visual behavior patterns. Instead of using a single universal progressive lens design, the invention analyzes individual eye and head movement characteristics and generates optimized lens surfaces with locally adapted optical properties. This allows the lens to provide continuous correction where needed while minimizing peripheral aberrations in specific zones based on the wearer's actual usage patterns.

The patent implements dynamics by transitioning from static, pre-defined progressive lens designs to dynamic, adaptive lens customization. The system captures real-time eye and head movement data during visual tasks, processes this information to identify individual visual behavior patterns, and generates optimized lens designs accordingly. This dynamic approach allows the lens characteristics to be adapted to each wearer's specific needs while maintaining manufacturing feasibility through automated design generation and numerical control machining.

The patent applies preliminary action by analyzing and predicting a wearer's visual behavior patterns before lens manufacturing. Through eye and head movement tracking during various visual tasks, the system pre-identifies the specific lens areas and orientations that will be most frequently used by that individual. This preliminary analysis allows the progressive lens design to be optimized in advance, concentrating optical quality in the predicted usage zones while minimizing aberrations in those specific areas, rather than attempting to uniformly optimize all possible lens regions.
