Prevalence of congenital color vision deficiency (CCVD) among drivers in United Arab Emirates (UAE)

Le résumé fourni par la source

Purpose: This study was conducted to determine the prevalence of color vision deficiency (CVD) and create awareness about the burden of CVD among drivers. Methodology: This was a retrospective cross-sectional study of 3486 participants (men, n = 2789) who applied for/renewed their drivers’ licenses in Al Ain City, Abu Dhabi, United Arab Emirates (UAE). All drivers had their visual acuity (VA) and color vision measured using standard procedures and the data was analyzed using descriptive statistics. Results: The overall prevalence of CVD was 3.13% (95% CI: 2.59–3.75). No participants had visual impairment (best-corrected distance VA worse than 6/18) and no female driver had CVD. The prevalence of CVD among the male drivers was 3.91% (95% CI: 3.25–4.69), and more among the younger drivers (18–29 years). Conclusion: Although the prevalence of CVD was low, to ensure inclusivity and the safety of all road users in the UAE, it is recommended that traffic lights and road signs that mainly use connotative color coding be adapted to include denotative clues which can be interpreted by drivers with CVD. A prospective study in all approved eye testing centers for drivers should be conducted to obtain representative CVD data of drivers in the UAE.
