COLOUR VISION TEST AMONG SCIENCE LABORATORY TECHNOLOGISTS IN NASARAWA STATE UNIVERSITY, KEFFI

Color -blindness is the inability to differentiate between some colors that other people can do. Using Ishihara test, the results indicate the prevalence of color vision deficiency in the technological profession. This research aimed to study color blindness prevalence among technologists in the laboratories of Nasarawa State University, Keffi. A cross- sectional descriptive and analytical study was conducted among 45 staff of the laboratories in the school to detect color vision problems using Ishihara Test. The result of the research shows that 10 in 28 men and 1 in 17 women suffer from various forms of defective colour vision. The research revealed that the degree of colour vision disability varies widely with age; it also revealed that the colour vision defects are prevalent in men than in women. But the results showed that there is no significant correlation between color blindness defect and exposure to chemical agents, type of job, history of familial defect and race. We suggest that color blindness as medical conditions should restrict employment choices for laboratory technicians and technologist s job in Nasarawa State University, Keffi.
