Role Of Eye Exercise In Astigmatism: Power Of Visual Training

Ayurveda has stated the importance of eye with a quote “Sarvendriyanam nayanam pradhanam” (1). Timira(2) is classified as one of the Dristigata rogas and is referred to as a paramadharuna vyadhii(3), which means it is progressive and can lead to blindness. Timira covers a wide range of refractive errors, including astigmatism. Astigmatism is a type of refractive error in which refraction varies in different meridians of the eye, consequently the light rays entering the eye cannot converge to a point of focus, but form various focal lines(4). Standard management primarily relies on spectacles, contact lenses, or surgical correction; however, interest in complementary and non-invasive interventions has grown. American ophthalmologist William H Bates in his book “Perfect eye sight without glasses” -advised a number of eye exercise for managing refractive errors including astigmatism(5). Eye exercises such as Bar exercise, Focus shifting exercise, Rolling exercise, Trataka yoga kriya have been proposed as a supportive approach for individuals with astigmatism, particularly to alleviate visual discomfort and improve ocular efficiency. These exercises generally target strengthening of extraocular and ciliary muscles, improving accommodation, enhancing binocular coordination, and reducing digital eye strain. While eye exercises cannot directly alter corneal curvature or eliminate the refractive error, they may contribute to improved visual function, better focusing stability, and reduced asthenopic symptoms such as headaches, eye fatigue, and difficulty in sustaining reading tasks. This paper highlights the importance of eye exercise, its positive impact on visual comfort and improving the quality of life in astigmatic patients.
