Wearable Improved Vision System for Color Vision Deficiency Correction

Abstract

Color vision deficiency (CVD) is an extremely frequent vision impairment that compromises the ability to recognize colors. In order to improve color vision in a subject with CVD, we designed and developed a wearable improved vision system based on an augmented reality device. The system was validated in a clinical pilot study on 24 subjects with CVD (18 males and 6 females, aged 37.4 ± 14.2 years). The primary outcome was the improvement in the Ishihara Vision Test score with the correction proposed by our system. The Ishihara test score significantly improved (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} }{}$p = 0.03$ \end{document}) from 5.8 ± 3.0 without correction to 14.8 ± 5.0 with correction. Almost all patients showed an improvement in color vision, as shown by the increased test scores. Moreover, with our system, 12 subjects (50%) passed the vision color test as normal vision subjects. The development and preliminary validation of the proposed platform confirm that a wearable augmented-reality device could be an effective aid to improve color vision in subjects with CVD.

Ophthalmic Wearable Devices for Color Blindness Management

“…Melillo et al developed a real‐time wearable augmented reality system. [ 62 ] This prototype, unlike the ones in the previous studies, is not based on any commercial smart glass (Epson or Google); it is custom‐made to aid CVD patients. The system consists of three main modules: acquisition, processing, and rendering.…”

Evaluation of central macula, retinal nerve fiber layer, and ganglion cell complex thickness in congenital color vision deficiency

“…A maldevelopment in 1 or more cone cells in the retina causes congenital CVD (2). The human retina has 3 types of photoreceptors: short-, medium-, and long wavelength-sensitive cones, which constitute normal human color vision (3). CVD usually occurs due to the absence of 1 or more retinal cone photopigments, result-ing in total or partial loss of sensitive function (4).…”
