Archery Eyewear Lens Spectral Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eyewear technologies do not effectively address the visual challenges faced by athletes in sports archery, particularly in maintaining focus on the yellow center of the target during long competitions, as the eye becomes fatigued and colors may blur, leading to reduced concentration and performance.
Innovation Solution
A lens for eyewear with specific transmittance characteristics, featuring a high transmittance in the yellow color range and low transmittance in the adjacent red range, reducing visual distraction and enhancing focus on the target center by making the red rings appear grey or black, thereby reducing eye fatigue and improving concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the athlete focuses on the yellow center field during long competitions, then the target center is clearly visible, but the eye becomes exhausted and colors become blurred
Solution Approach 1:
The patent applies color filtering by selectively transmitting yellow wavelengths (560-580 nm) while absorbing red wavelengths (600-680 nm). This color separation enhances the yellow center field visibility and reduces chromatic distraction from red rings, allowing sustained focus during long competitions without eye fatigue or color blurring
Solution Approach 2:
The patent modifies the optical parameters of the lens by defining specific transmittance ranges: yellow light transmittance of 30-90% and red light transmittance of 0-10%. This parameter optimization creates a spectral filter that enhances target center visibility while reducing overall visual noise, enabling prolonged concentration during multi-hour competitions
2Loss of information
If the red rings are brightly colored to indicate scoring zones, then the target is more recognizable, but visual distraction increases and concentration decreases
Solution Approach 1:
The patent uses selective color filtering to transmit yellow wavelengths (560-580 nm) while blocking red wavelengths (600-680 nm). This causes the red rings to appear dark or gray while the yellow center remains bright, reducing visual distraction from surrounding rings and enhancing concentration on the target center without losing target recognition
Solution Approach 2:
The patent applies differential transmittance to different spectral regions: high transmittance for yellow (30-90%) and low transmittance for red (0-10%). This local optimization of optical properties enhances the yellow center field visibility while suppressing red ring visibility, creating a visual hierarchy that improves concentration
3Adaptability or versatility
If standard colored targets are used, then the target is visually appealing and informative, but eye fatigue increases during long exhibitions
Solution Approach 1:
The patent transforms the visual appearance of the target by filtering yellow light transmission while blocking red light. This makes the yellow center field appear bright and the red rings appear dark or gray, reducing chromatic contrast and visual noise that cause eye fatigue during long exhibitions while maintaining target visibility and information
Solution Approach 2:
The patent optimizes transmittance parameters to reduce eye strain: yellow light transmittance set at 30-90% and red light transmittance set at 0-10%. This parameter configuration reduces the overall chromatic load on the eyes during prolonged viewing while maintaining adequate target visibility and scoring zone differentiation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The lens design significantly enhances the athlete's ability to focus on the target center by minimizing visual noise from the red rings, allowing for better concentration and performance over extended periods by maintaining a high transmittance in the yellow range and reducing transmittance in the red range, thus improving overall shooting performance.
