Wearable Accommodation Remote Control for Ophthalmic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Presbyopia, a progressive age-related loss of accommodative strength, affects millions, and existing solutions for accommodating ophthalmic devices are complex and invasive, lacking intuitive user experience.
Innovation Solution
An accommodation remote control worn on the upper extremity measures focal distance between the user's hand and face, computing an accommodation value to wirelessly adjust the optical power of ophthalmic devices, such as contact lenses or glasses, providing real-time feedback for improved focus adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing solutions for accommodating ophthalmic devices are implemented, then accommodative power adjustment is achieved, but device complexity and invasiveness increase
Solution Approach 1:
The patent introduces a wearable computing device as an intermediary between the user and the ophthalmic device. This mediator communicates with both the user (receiving input) and the ophthalmic device (transmitting control signals), thereby simplifying the overall system architecture and improving ease of operation without requiring direct complex integration between the user's physiological systems and the ophthalmic device.
Solution Approach 2:
The accommodation control system is divided into separate functional modules: a wearable computing device for processing and control, and the ophthalmic device for optical correction. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining intuitive user experience.
2Ease of operation
If existing solutions for accommodating ophthalmic devices are implemented, then focal distance adjustment is achieved, but invasiveness increases
Solution Approach 1:
The wearable computing device serves as a non-invasive intermediary that translates user intent into device control signals. This approach eliminates the need for invasive surgical modifications or direct neural interfaces, achieving intuitive control without harmful invasive procedures.
Solution Approach 2:
The patent replaces mechanical or surgical accommodation adjustment mechanisms with an electronic control system. The wearable computing device communicates wirelessly or via cable with the ophthalmic device, substituting invasive mechanical adjustment methods with non-invasive electronic control.
3Measurement precision
If manual accommodation adjustment is used, then user control is achieved, but precision and responsiveness to focal distance changes deteriorate
Solution Approach 1:
The system implements automatic feedback control where the wearable computing device continuously monitors user needs and automatically adjusts the ophthalmic device's focal distance settings. This feedback mechanism achieves high measurement precision and responsiveness without requiring complex manual adjustment operations by the user.
Solution Approach 2:
The accommodation control system performs self-adjustment based on automated detection of user needs. The wearable computing device independently processes information and controls the ophthalmic device without requiring complex manual intervention, thereby achieving high precision while maintaining ease of operation.

AI summary
An accommodation remote control includes a housing adapted for wearing on an upper extremity of a user, a range-finding sensor, a wireless transmitter, and a controller. The controller causes the accommodation remote control to perform operations including: emitting a range finding signal from the range-finding sensor to measure a distance between the accommodation remote control and a body part of the user, determining an accommodation value for an ophthalmic device based upon the distance measured with the range-finding sensor, and transmitting an accommodation control signal from the wireless transmitter to adjust an optical power of the ophthalmic device. The accommodation control signal is based upon the accommodation value.
