Background: Color vision deficiency is an abnormal condition characterized by the inability to clearly distinguish different colors of the spectrum. Methods: The study was done in the Postgraduate Department of Physiology, Government Medical College Srinagar. The study was conducted in OPDs of SMHS hospital and District hospitals of Kashmir. A sample 3110 was selected. Detailed informed consent was taken from subjects / patients and relevant information regarding name, age, gender, consanguity, marital status, education, medical history and drug history was collected on structured proforma. Results: A total of 3110 participants were included in the study.1462 (47%) were males. The mean age of the study participants was 34.72 +_14.862 years.871 (28%) and 892 (28.7%) belong to the age group of 21–30 & 31–40 years respectively. Among the types of color vision deficiency, Deuteranomalia is the most common type prevalent in the Kashmiri population i.e: 52.74% followed by Protanopia (21%). The least common defect was protanomalia (11.64%).Conclusion: Our study of color vision deficiency among adult Kashmiri population shows the significant gender based difference in the frequency of color vision deficiency, with higher in males (8.5%) than in females (1.3%). The assessment of color vision deficiency by Ishihara pseudo isochromatic plates is rapid, cost efficient and sensitive in detecting red–green color vision deficiency.
