Rising Myopia Cases in Chennai Raise Concerns Over Screen Time and Outdoor Activities
Myopia, commonly known as near-sightedness, has been steadily on the rise in urban India, including Chennai. Ophthalmologists are exploring various treatments, from medications to multifocal lenses, to slow its progression. However, experts agree that the most effective way to combat myopia is by reducing screen time and encouraging children to spend more time outdoors.
The prevalence of myopia in children aged 5 to 15 in urban India has significantly increased, from 4.44% in 1999 to 21.15% in 2019. According to a study conducted by Hyderabad-based L V Prasad Laboratory, this figure is expected to rise dramatically, reaching 31.89% by 2030, 40.01% by 2040, and 48.14% by 2050. These alarming predictions highlight the growing concern surrounding myopia’s impact on future generations. In Tamil Nadu, the government’s annual eye screening for school students reports a prevalence of around 7%. Although students are provided free spectacles, the compliance rate remains low, with only one in five students wearing them consistently. Public health experts suggest that improving spectacle frame quality, educating both students and parents, and involving teachers could significantly increase compliance and effectiveness.
Digital eye strain (DES) is also a significant contributor to the rise in myopia, with 50-60% of children affected, largely due to excessive screen time. Dr. S Soundari from Dr Agarwal’s Eye Hospital emphasizes the importance of raising awareness about myopia prevention and management, especially among schoolchildren and their parents. In response, the hospital will host a patient summit in Chennai on January 4, 2025, focusing on myopia and digital eye strain.
Doctors in private schools report that the incidence of myopia among students exceeds 20%, with one in five students wearing spectacles. Common treatments include multifocal contact lenses that utilise Defocus Incorporated Multiple Segments (DIMS) technology, which slows the progression of myopia by incorporating honeycomb-shaped treatment areas. Additionally, low-dose atropine eye drops have proven effective in preventing the elongation of the eyeball, the primary cause of myopia. As myopia cases continue to rise, public health initiatives and awareness campaigns will be crucial in addressing this growing issue.
