Solution Overview
Problem
Existing eye protection lenses fail to effectively address the increasing issue of myopia and visual health problems despite their ability to block ultraviolet and blue light, leading to prolonged eye strain and fatigue.
Innovation Solution
A manufacturing process involving anti-blue light and anti-ultraviolet treatments, combined with a multi-layer optical coating, is applied to lenses, using specific ratios and temperatures for soaking and coating, to enhance light transmission and reduce surface reflection, with a transmittance of at least 96% and a wavelength range of 630-750 nm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing lenses block ultraviolet and blue light, then eye protection against radiation is improved, but visual clarity and light transmission are reduced
Solution Approach 1:
The patent divides the optical filtering function into separate layers: the bulk lens material blocks UV and blue light, while the multi-layer optical coating on the surface manages light reflection and transmission. This segmentation allows each layer to be optimized independently for its specific function.
Solution Approach 2:
The patent uses composite material structure combining a lens material (with specific refractive index and Abbe number) and multiple coating layers with different optical properties. The composite structure achieves both radiation blocking and high light transmission by combining materials with complementary characteristics.
2Object-affected harmful factors
If lens material blocks more radiation, then eye protection is improved, but transmittance and visual clarity deteriorate
Solution Approach 1:
The patent applies different optical properties to different parts of the lens system: the bulk material provides radiation blocking, while the surface coating layers provide selective light transmission. Each layer has locally optimized properties for its specific function in the optical path.
3Illumination intensity
If multi-layer optical coating is applied, then light transmission is improved, but manufacturing complexity increases
Solution Approach 1:
The patent optimizes specific parameters of the coating layers (thickness, refractive index, material composition) to achieve high light transmission. By carefully controlling these parameters within specific ranges, the patent achieves optimal performance while managing manufacturing complexity.
