Many ocular diseases can affect color vision of a patient which will ultimately reduce many daily based activities. Measuring color vision of a patient can help deciding any management plan for that patient. Objectives:To compare the validity of electronic color vision test with conventional pseudoisochromaticishihara plates and to find out easiest and appropriate method of color vision testing.Methods: This was a cross-sectional study involving the use of structured proforma and questionnaire to evaluate the validity of electronic color vision test and conventional ishihara plate test. A sample size of 80 individuals with normal and mild degree of refractive error was examined and results were recorded in self-designed proforma. Results: Eighty individuals were enlisted; 35 were males (43.8%) and 45 (56.3) were female; age ranged from 14 to 56 (average 34.2+ 12.2) years. By conventional ishihara testing 68 patients gave 100% results (n = 68; 85%) and 12 gave 75% (n = 12; 15%) results. In electronic color vision test 69 individuals gave 100% ( n = 69; 86.3%) results and 11 gave 75% (n = 11; 13.7%) results. 45% peoples are satisfied with their electronic color vision test, 20% satisfied with both methods however 35% are satisfied with conventional method. Prevalence of color vision defect is higher in males as compared to females. Conclusions: This study found that the sensitivity and specificity of electronic color vision test and conventional ishihara test is nearly similar (p< 0.05). Electronic Ishihara color vision test is also a way of self assesment and also has the advantage of reducing the cost through decreasing resources and the time to analyze the results.
