Ophthalmic Lens Selection via Visual Range Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The selection of ophthalmic eyeglasses and frames is challenging due to the complexity of parameters involved, making it difficult for opticians to objectively assess and communicate technical aspects to wearers, as existing measurement systems provide raw, abstruse numbers that hinder dialogue.
Innovation Solution
A method involving measurement of characteristic parameters using a device, constructing images with bounded ranges to visually represent measured values, and displaying these on a screen, allowing wearers to understand their positions relative to a population's norms, with processing distributed between a shop and a remote computer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement systems are used to objectively analyze frame position and behavioral parameters, then measurement precision is improved, but the complexity of data representation increases making it difficult for wearers to understand
Solution Approach 1:
The patent introduces an intermediary processing system that transforms raw measurement data into visual representations. The measurement device captures precise objective data about frame position and behavioral parameters, but this data is then processed by a computer system that converts it into visual images showing the relationship between measured values and population norms. This intermediary step resolves the contradiction by maintaining measurement precision while eliminating data representation complexity for the wearer.
Solution Approach 2:
The patent replaces the mechanical/physical presentation of complex measurement data with visual information processing. Instead of presenting raw numerical data or requiring complex physical demonstrations, the system uses visual images to represent the relationship between individual measurements and population distributions, making the information accessible and understandable while maintaining objective measurement precision.
2Ease of operation
If all processing is done locally in the shop, then ease of operation is improved, but use of energy and computational resources increases
Solution Approach 1:
The patent segments the processing tasks between local and remote systems. The measurement device locally captures data and the local computer generates visual representations, but the comparison with population norms and generation of reference distributions can be performed remotely. This segmentation allows the shop to maintain ease of operation with local processing capability while reducing energy consumption by distributing computational loads to remote servers that can handle heavy processing without constraining the shop's energy resources.

AI summary
A method for aiding the choice, by a future wearer, of a piece of visual equipment including at least one ophthalmic lens and a spectacle frame, includes the following steps: receiving at least first and second data items representative of first and second distances measured between an eye of the wearer and the frame; determining a first width and a second width, associated with the first data item and the second data item, respectively, by comparing, for each data item, the lower and upper limits of a range of values associated with the distance represented by the data item in question; and constructing an image including a first portion having the first width and a second portion having the second width, the first portion and the second portion being juxtaposed in the image. A method allowing a future wearer to select such a piece of equipment is also described.
