Indian Opinion Analysis
The issue of prolonged blue light exposure is increasingly relevant for India given its significant reliance on digital technology for work and education. As device usage continues to rise post-COVID with remote work/learning trends entrenched in urban society, health risks like disrupted sleep cycles or long-term retinal damage could emerge as national concerns. Additionally, affordable access to protective solutions such as tinted sunscreens or anti-blue-light eyewear needs attention within price-sensitive Indian demographics.

Moreover, awareness campaigns about proper device usage habits can play an essential role in addressing this problem proactively across diverse geographies-from tech-centric metros to rural areas rapidly adopting digital tools through government initiatives like Digital India.
