Impact of Yogic Intervention on Refractive Error Among Adolescents: An Experimental Study

Refractive errors are a significant public health concern, particularly among adolescents. The increasing reliance on digital devices and reduced outdoor activity has contributed to a rise in myopia and other refractive anomalies. This study aims to assess the effectiveness of a structured yogic intervention in improving refractive errors among school-going adolescents through a controlled experimental design. A total of 120 adolescents aged 10–19 years were selected and divided into experimental (n=60) and control (n=60) groups. The experimental group underwent a 90-day yoga program. Refractive error (spherical equivalent in diopters) was measured using autorefractometer. Data were analyzed using descriptive statistics, independent sample t-tests, and variance testing. The experimental group showed significant improvements in both eyes. In the right eye, the mean improved from –1.317 D to –0.954 D (p = 0.004), and in the left eye from –1.350 D to – 1.058 D (p = 0.003). Variance and t-tests confirmed statistical significance in the post-intervention values of the experimental group. Whereas a downward trend was observed in the control group. The study supports yoga as an effective, non-invasive, and cost-efficient complementary therapy for managing adolescents’ refractive errors.
