Red Light Augmentation for Display Eye Strain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Increased screen time due to remote work has led to excessive blue light exposure, causing eye strain and potential retinal damage, particularly affecting older users whose vision declines with age, as current display technologies do not emit restorative deep red light.
Innovation Solution
An information handling system integrates a red light source emitting light in the 650-800 nm spectrum, which provides restorative illumination based on user interactions and visual acuity tests, customized to alleviate eye strain and improve visual acuity by emitting red light at specific intervals or in response to blue light exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If display technologies use blue light emitting diodes to create visual images, then color display capability is improved, but retinal damage and eye strain increase
Solution Approach 1:
The patent applies this principle by using red light (650-800nm) to counteract the harmful effects of blue light exposure. The red light source converts the harm caused by blue light (retinal damage, eye strain) into a benefit through restorative illumination that improves mitochondrial energy production in retinal cells, thereby healing the damage caused by the display's blue light backlight.
2Productivity
If employees increase screen time for remote work interactions, then work efficiency is improved, but blue light exposure increases causing eye strain
Solution Approach 1:
The system incorporates visual acuity testing that provides feedback to both users and employers about eye health status. The processor executes instructions to present visual acuity tests, measure results, and provide feedback reports, enabling continuous monitoring and adjustment of red light therapy based on actual eye health conditions resulting from screen time exposure.
Solution Approach 2:
The red light source acts as an intermediary between the harmful blue light exposure and the retinal cells. Rather than eliminating screen time or blue light, the system introduces red light as a mediating element that protects and restores retinal cells, allowing continued productive screen use while mitigating harmful effects.
3Illumination intensity
If display backlights emit blue light for image definition, then visual image quality is improved, but melatonin production is impacted affecting sleep quality
Solution Approach 1:
The system implements periodic red light therapy sessions that complement the daily rhythm of blue light exposure from displays. By providing restorative red light at specific intervals (e.g., after screen sessions or in the evening), the system counteracts the cumulative impact of blue light on melatonin production, allowing users to maintain high-quality display usage while preserving sleep quality through periodic restoration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces eye strain by providing personalized red light therapy, improving visual acuity and tracking its effectiveness through repeated tests, offering a therapeutic solution for users exposed to prolonged screen time.
Implementation Method 1
A red light source provides red light from a restorative spectrum range, such as 650 to 800 nm
Implementation Method 2
exposing the retina to light waves spanning 650-800 nm can improve mitochondrial energy production
Data Source
AI summary
End user interactions at a display are monitored for predetermined conditions to provide augmentation of display presentation by a red light that illuminates in the 650 to 800 nm range, such as at substantially 670 nm. Instructions stored in non-transient memory and executed on a processor present visual images of varied color contrast and evaluate end user inputs to determine an end user visual acuity. Over time and use of the display and red light, end user visual acuity is periodically tested to evaluate the effectiveness of red light illumination to restore visual acuity.
