Wearable Improved Vision System for Color Vision Deficiency Correction.

Area of Science:

• Ophthalmology
• Human-Computer Interaction
• Biomedical Engineering

Background:

• Color vision deficiency (CVD) is a common visual impairment affecting color recognition.
• Existing solutions for CVD often lack accessibility and real-time correction capabilities.

Purpose of the Study:

• To design and develop a wearable augmented reality (AR) system to enhance color vision in individuals with CVD.
• To clinically validate the effectiveness of the AR system in improving color discrimination abilities.

Main Methods:

• A pilot study involving 24 participants (18 males, 6 females) with CVD was conducted.
• The study assessed the improvement in Ishihara Vision Test scores using the AR system.
• Participants' color vision was evaluated with and without the AR device.

Main Results:

• The Ishihara test scores significantly improved from 5.8 ± 3.0 without correction to 14.8 ± 5.0 with the AR system.
• Nearly all participants demonstrated enhanced color vision, evidenced by increased test scores.
• 50% of participants using the AR system achieved scores comparable to those with normal color vision.

Conclusions:

• The developed wearable AR system is a promising aid for improving color vision in individuals with CVD.
• Preliminary validation confirms the potential of AR technology to effectively assist those with color vision impairments.
• This innovation offers a novel approach to managing and mitigating the effects of color vision deficiency.
