Solution Overview
Problem
Existing light therapy devices hinder the wearer's vision and are energy-inefficient, making them impractical for continuous use.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light guiding plate is roughened or coated with white paint to reflect light to the eyes, then light delivery effectiveness is improved, but the plate becomes non-transparent and obstructs the wearer's vision
Solution Approach 1:
The light guiding element is segmented into multiple sections: a first section that receives light from the light source, a second section that guides light to the eyes, and a third section that reflects light. This segmentation allows different portions to have different optical properties, enabling both effective light delivery and transparent vision areas.
Solution Approach 2:
Different sections of the light guiding element have different optical qualities. The first section is designed for light reception, the second for transparent light guidance, and the third for light reflection. This local differentiation of optical properties resolves the contradiction between light delivery effectiveness and vision transparency.
2Illumination intensity
If multiple light sources are integrated into the glasses frame, then light treatment effectiveness is improved, but energy consumption and device complexity increase
Solution Approach 1:
The patent combines multiple light sources (first and second light sources) into a single integrated frame structure with a unified light guiding element. This merging approach allows coordinated light delivery while sharing common structural components, reducing overall device complexity despite multiple light sources.
Solution Approach 2:
The light guiding element serves multiple functions: it guides light from the first light source to the eyes, guides light from the second light source to the eyes, and reflects light from both sources. This multi-functionality reduces the need for separate components for each light source, thereby reducing overall device complexity.
3Ease of manufacture
If a light guiding element is provided without notches to maintain structural simplicity, then manufacturing is easier, but light distribution uniformity and design flexibility are reduced
Solution Approach 1:
The light guiding element features notches at specific locations (first notches and second notches) to create localized optical effects. These notches enable light to pass through or be reflected at specific positions, providing design flexibility for light distribution while maintaining the overall simplicity of the light guiding structure.
Solution Approach 2:
The notches segment the light guiding element into distinct optical zones, allowing different regions to perform different functions (light passage, light reflection, light guidance). This segmentation provides design freedom for controlling light distribution while maintaining structural simplicity through the unified light guiding element design.

AI summary
The invention relates to glasses provided with two transparent spectacle glasses enclosed in a frame. Each spectacle glass is positioned in front of a person's eye with the aid of a frame to be positioned on the ears and nose of said person. The glasses are further provided with at least one light source integrated in the frame for directly and / or indirectly delivering light to the eyes substantially from above. A nose frame part of the frame reflects at, at least, a nose frame side portion facing the eye, to the eye at least partially the direct or indirect incident light thereon originating from the light source.
