Tele-Optometry and Mobile Eye Care Units: A Rural Vision Care Model for India

Abstract

India accounts for about 20% of the world’s visually impaired population. Rural and underserved populations are disproportionately affected by avoidable causes of blindness such as uncorrected refractive errors, cataracts, diabetic retinopathy, and glaucoma. Traditional facility-based eye care systems have often remained ineffective in reaching these communities due to geographic isolation, a very low number of ophthalmologists in rural areas, and persistent infrastructure deficits. This paper reviews the integration of tele-optometry and mobile eye care units into a scalable hybrid public health model to address these access gaps in India. A structured literature search was conducted through PubMed, Scopus, and Google Scholar for articles published between 2015 and 2025 using the terms “tele-optometry,” “mobile eye care,” “teleophthalmology,” “vision screening,” and “rural eye health India.” National policy documents and institutional program reports were also reviewed. The evidence indicates that hybrid models integrating mobile diagnostic outreach with remote specialist consultation improve screening uptake, facilitate the early detection of ocular diseases, reduce patient travel burden, and strengthen referral pathways. However, significant barriers remain in large-scale implementation, including unreliable rural digital connectivity, shortages in the optometry workforce, high operational costs, the absence of optometry-specific telemedicine regulations, and limited digital literacy among target populations. In addition, long-term clinical outcome and cost-effectiveness data remain limited. Strategic alignment with existing national health programs, along with regulatory reform, workforce development, and longitudinal research, is required for the sustainable integration of this model into India’s eye care system.
