Personalized Ophthalmic Lens Light-Filter Pattern Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmic light filters are designed based on standard populations and limited scenarios, failing to adapt to individual wearer needs, leading to visual discomfort due to inadequate consideration of physiological characteristics, visual behavior, and environmental factors.
Innovation Solution
A method for determining a personalized light-filter pattern for ophthalmic lenses by collecting data on the wearer, including sensitivity, gaze direction, biological features, and frame wearing habits, to customize the pattern parameters such as position, shape, and optical properties of light-filtering zones, using a combination of measurements and virtual reality simulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If light filters are designed based on reference population data and limited scenarios, then the design process is simplified and can be standardized, but the filters cannot be adapted to individual wearer needs and specific environments, resulting in visual discomfort
Solution Approach 1:
The system performs preliminary data collection about the wearer's visual characteristics,用眼 habits, and environmental conditions before the lens manufacturing process. This advance information gathering enables personalized filter design without complicating the actual manufacturing, as the customization parameters are determined beforehand through questionnaires and measurements.
Solution Approach 2:
The invention changes the approach from fixed standardized parameters to variable personalized parameters. By collecting individual wearer data and using it to determine specific filter characteristics (transmission rates, spectral filtering, zone positioning), the system adapts the filter parameters to each user's needs while maintaining a standardized manufacturing process that accepts these personalized specifications.
2Ease of operation
If complex light-filtering zones are introduced at different positions on the ophthalmic lens, then visual comfort is improved for specific activities, but the device complexity increases
Solution Approach 1:
The invention applies different light-filtering properties to different zones of the ophthalmic lens based on the wearer's specific needs. Each zone can have customized transmission characteristics, spectral filtering, and positioning optimized for particular visual tasks (e.g., computer work, outdoor activities, nighttime driving), providing localized quality enhancement without requiring the entire lens to be complex.
Solution Approach 2:
The light-filter pattern is divided into multiple independent zones with distinct functions. Each zone can be independently designed and adjusted based on the wearer's activities and environmental conditions, allowing complex functionality to be broken down into manageable segments that are simpler to manufacture and adjust individually.
3Adaptability or versatility
If dynamic filters capable of darkening on specific parts of the lens are used, then adaptability to different lighting conditions is improved, but the device complexity and cost increase
Solution Approach 1:
The invention introduces dynamic capabilities through adjustable light-filter zones that can modify their transmission properties in response to different lighting conditions and wearer needs. This dynamic behavior is achieved through controllable filter elements that can be adjusted electronically or mechanically, providing adaptability without requiring a completely complex reconfiguration of the entire lens system.
