A Study to Assess the Effectiveness of Video Assisted Teaching Program on Knowledge Regarding Refractive Errors Among School Going Children in Selected Schools at Bangalore

Abstract

The focus of this study to assess the effectiveness of video assisted teaching program on knowledge regarding refractive errors among school going children in selected schools at Bangalore. Eyes are the reflector of the soul and the body’s casement to the outside world. The goal of learning initiate in childhood and the correctness of a child’s vision can extremely affect or alter his/her learning capacity. This type of vision error also known to be called as refraction error is a problem with focusing light accurately on the retina due to the shape of the eye thus reducing normal vision. Treating refractive errors is relatively effortless and considered as one of the easiest ways to reduce impaired vision. Three main types are referred to as refractive errors hypermetropia (farsightedness), myopia (nearsightedness) and astigmatism. Schools going years are thought to be as wonder years in a person’s life. According to WHO, published in 2014, 14 million children are incurable blind all their lives and visual rehabilitation interventions are essential for their full psychological and personal development. An approximate 19 million children who are below 15 years of age, are visually impaired. Among them, 12 million children experiencing with refractive errors, a condition that could be sort out after an appropriate diagnosis. According to JPHMR (Journal of Public Health and Medical Research), it is estimated that 153 million people over 5 years of age were visually impaired as a result of uncorrected refractive errors. An observational study conducted in Mysore district 2015, revealed that there were approximately 12.8 million children in the age group 5 years to 15 years who were visually impaired from uncorrected refractive errors estimating a global prevalence of 0.96%. The prevalence of childhood blindness in India is 0.17%. Unremedied refractive error may have brunt to a larger extent on the learning ability of the student. Prompt and well-timed detection and regular interventions can help improve child’s potential tremendously during the formative years.
