AR Lens Testing Visualizing Blue Light Protection

Solution Overview

Problem

Individuals struggle to evaluate their eye protection needs against blue and ultraviolet radiations, as these forms of light are often invisible or faintly visible, and existing simulation devices do not effectively account for non-visible optical features of lenses when selecting eyeglasses.

Innovation Solution

A method and electronic device that uses augmented reality to visualize the presence of blue/ultraviolet light in the environment and the protective effects of lenses, by capturing images, measuring light intensity, and displaying a corrected image that includes graphical representations of light transmission and reflection, allowing users to test lenses' effects on harmful light.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If conventional simulation devices are used to test lenses, then the device complexity is reduced, but the ability to detect and measure non-visible light (blue/ultraviolet) is insufficient

Engineering Contradiction:
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary device (smartphone with specific application) that acts as a mediator between the lens and the user's perception. The smartphone captures images through the lens and processes them to visualize invisible blue/ultraviolet light effects, thereby enabling detection without requiring complex specialized equipment directly in the testing device.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical/optical simulation device components with electronic/digital systems. Instead of using complex optical filters and displays, the invention uses a smartphone camera, image processing algorithms, and software-based visualization to detect and display the effects of blue/ultraviolet light transmission and reflection.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If the simulation device displays only visible light, then the ease of operation is maintained, but the information about harmful non-visible radiation is lost

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent applies color changes to represent invisible blue/ultraviolet light effects. The application processes captured images and applies color overlays or modifications to visualize the transmission and reflection of harmful light, allowing users to perceive information that would otherwise be invisible while maintaining the simple operation of viewing images on a smartphone screen.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent adds an informational dimension to the visual output. By overlaying processed information about blue/ultraviolet light transmission and reflection onto the captured images, the system provides additional dimensional data without complicating the basic operation of viewing test results on a familiar smartphone interface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Measurement precision

If the lens optical features are not visualized, then the device complexity is low, but the measurement precision of lens protective effects is insufficient

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a copied and enhanced version of the captured image that includes visualized information about lens optical features. The application processes the original captured image and generates a modified copy that overlays or highlights the transmission and reflection characteristics of blue/ultraviolet light, enabling precise evaluation without requiring complex additional measurement equipment.

Inventive Principle:
Principle #26Copying
