Background: Color vision impairment affects 3-4% of people in India, and it goes unnoticed until later in life because people develop adaptations to cope to some extent, while others are unaware of the disease. The goal of this study is to determine the prevalence of color vision impairment in students aged 6 to 15 in various Jalandhar schools. Methods: A prospective community-based study of 5000 students was conducted to determine the prevalence of color vision impairment. Students were tested using the 38th edition of Ishihara Pseudoisochromatic Color Plates. If the student had a color vision impairment, it was further classified. The collected data was compiled and analyzed to determine the prevalence of color vision impairment, gender-specific prevalence, and the prevalence of different types of color vision impairment. Students between the ages of 6 and 15 from 15 different schools were screened. The study included 5000 students, with 2022 (40.44 percent ) males and 2978 (59.56 percent ) females. 85 students (1.7 percent) had color vision impairment, with 79 (1.58 percent) males and 6 (0.12 percent) females. Among the colorblind, 79.94 percent were protanopes, 6.05 percent were deuteranopes, and none were tritanopes. Protanopes were 75 (94.94 percent ) males and 4 (5.06 percent ) females, while deuteranopes were 4 (66.7 percent ) males and 2 (5.06 percent ) females (33.3 percent ). Conclusion: Males are more likely than females to have color vision impairment. Protonopia is the most common type of color vision impairment, followed by deutronopia. Our study did not include any mention of tritanopia. It is strongly advised that children be screened for color vision impairment at a young age.
