This paper looks at the design, deployment, and impact of augmented reality (AR) virtual try-on systems in online eyewear retail, focusing on Lenskart. Lenskart is an Indian omnichannel eyewear retailer that has integrated AR and AI into its shopping experience, particularly through a “3D Try On” feature and facial analysis tools. This approach aims to reduce uncertainty in online purchases while improving conversion rates, customer satisfaction, and personalization. Using secondary data from company pages, product and blog posts, app descriptions, as well as industry and academic literature, this study reviews existing research on AR in e-commerce, details Lenskart’s AR capabilities, evaluates the benefits and limitations, and offers recommendations for further research and practical use. Key findings show that AR increases experiential value, reduces perceived risk, and enhances online adoption for visually evaluative products like eyewear. However, issues with technical accuracy, user experience design, accessibility, and privacy management continue to pose significant challenges.
