Online eyewear retailer Lenskart has invested US $0.5 million in California-based startup ThinOptics, which makes which makes innovative reading glasses that can stick to one’s nose or be attached to phone or keychain.

This investment is reportedly part of Ratan Tata-backed Lenskart’s plan to invest nearly $2-3 million in startups that are innovating in product and technology to make eyecare solutions affordable.

According to CEO Peyush Bansal, Lenskart is working closely with ThinOptics’ California team for growing the India market. Bansal added that response to ThinOptics in India was positive.
