Abstract: Introduction It is a state in which optical system of the eye fails to adjust to bring parallel rays of light to focus on proper place (fovea) and the size of the eyeball either increases or decreases because age factor which effects the eye focus. The global estimate of the total number of people of all ages with visual impairment is 253 million of which 36 million are blind . It is also estimated that 82% of people living with blindness are aged 50 and above. Studies from urban India suggest that 49.3 million of those aged ?15 years may have refractive errors. Cataract is the leading cause of blindness in Africa, affecting an estimated half of the seven million blind people in that continent. . Many studies confirmed that the high burden of blindness due to cataract in the Indian population especially in the older age group. So the objective of our study is to measure the significance and analyse the percentage of refractive error and cataract at varying age group (0-19), (20-39), (40-59), (60+) and to make awareness about these conditions in remote areas of Saifai town. Material & Method A community based cross sectional survey was done in the remote areas covering an area of 5 km. A rural program for control of blindness was conducted from December 2015 to March 2016. Out of 1700 patients a total of 1032 patients were included in the study of varying age groups i.e. (0-19, 20-39, 40-59, 60+). The research design used for this study is systemic random sampling without repetitions (SRSWOR). Result and Discussion The average mean of the age group 0-19 years was found to be 33.33% and for 20-39 was found to be 13.66% for 40-59 year the mean value calculated was 27.80% and for the age group above 60 the calculated average mean was found to be 25.56%. The female responders were found more 48.83% without refractive error and Cataract as compared to the male responders 40.40% in the age group 0-19 years. 22.96% responders were diagnosed with refractive error with the prevalence more in female 50.63% as compared to male 49.36% among all age groups. out of 307(29.74%) , the cataract rate was found to be more in male 53.74% than in females 46.25% %). Conclusion The study reveals that the older adults above 60 years have high prevalence of cataract an early diagnosis can prevent it from secondary complications like glaucoma etc. The prevalence of refractive errors was found more in the age group of 40-59 years thereby there is a need of eye care including early diagnosis and timely interventions for promotion of eye health at community level. There must be regular 6 month eye screening program for all the age group and mainly focusing on 40-59 years.
