Self-Service Optometric Apparatus for Contact Lens Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process for selecting contact lenses is cumbersome and often discourages potential users, especially new ones, due to the requirement of visiting a clinic for examinations, leading to a decrease in the use of hard contact lenses and a lower technical level among eye care practitioners.
Innovation Solution
An apparatus for optometric self-examination and a management server that allows users to acquire and display optometric data, enabling them to select suitable contact lenses independently, with the option to request a prescription from affiliated facilities, thereby reducing the time and complexity of the selection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users follow the traditional process of visiting a clinic for examinations and prescriptions, then contact lens selection accuracy is improved, but the process complexity and time required increase significantly
Solution Approach 1:
The system enables users to perform self-examinations using portable measurement devices and automatically generate contact lens prescriptions through the terminal device, eliminating the need for clinic visits and eye care practitioner involvement in the measurement and prescription process
Solution Approach 2:
The patent replaces the mechanical/physical examination process at the clinic with an automated electronic system that uses portable measurement devices to capture ocular data and automatically processes this data through algorithms to generate prescriptions
2Measurement precision
If users visit a clinic for contact lens prescription, then prescription accuracy is improved, but the time required for the process increases
Solution Approach 1:
The system performs all necessary measurements and calculations in advance through automated processing, allowing the prescription to be generated immediately at the terminal device without requiring subsequent clinic visits for examination and prescription writing
Solution Approach 2:
Users independently complete the entire prescription process using the terminal device, from self-examination to receiving the prescription, without requiring eye care practitioner time
3Reliability
If traditional clinic-based prescription process is used, then contact lens selection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system allows users to independently complete measurements and obtain prescriptions through the terminal device, making the process as easy as using a self-service kiosk while maintaining reliability through automated data processing and algorithm-based prescription generation

AI summary
An object of the present invention is to provide an apparatus for optometric self-examination, a management server and a contact lens selection system using the same that are readily available to a new user and additionally shorten a time period required by an eye care practitioner for prescription or, even if no eye care practitioner's prescription is provided, allow for selection of a contact lens preferred for the user. The apparatus for optometric self-examination includes an optometric data acquisition unit for determining at least a part of a shape of a cornea of a user in response to an operation by the user and acquiring optometric data, based on the shape of the cornea, and a contact lens data display unit for displaying a result of selection of a contact lens suited for the optometric data, based on the optometric data and the shape data of contact lenses.
