ABSTRACT

Colour blindness, also known as colour vision deficiency, is characterized by the inability to perceive different colours clearly. The career choices of colour-blind people may be limited for safety reasons. The aim of this study was to identify the prevalence of colour blindness among undergraduates in Chukwuemeka Odumegwu Ojukwu University, Uli campus, Uli, Nigeria. A cross-sectional study was conducted among 300 undergraduates, aged 17-28 years, from May to June 2024. Ocular visual acuity assessment using Snellen’s chart and a colour vision test with Ishihara plates were used. The data collected were analysed. The results revealed that the overall prevalence of the colour vision deficiency was 7.6% with the males having 4.3% while the females had 3.3%. Screening enables the students affected to become aware of limitations and devise ways of overcoming them.
