LensCart

LensCart is a mobile + web virtual try-on app focused specifically on eyewear, where accuracy matters more than flashy effects. Users scan their face once (with a short guided calibration) and then try frames with correct scale, pupillary distance alignment, and lens width fit. The app highlights “fit issues” (too wide, bridge too narrow, slips risk) and recommends sizes across brands that actually match your measurements. It also supports side-view estimation using a quick head-turn capture to reduce the common failure where frames look fine front-on but fail at the temples. LensCart can be offered as a consumer app for discovery and as a lightweight SDK/widget for independent optical shops that can’t afford enterprise AR solutions. Realistically, it won’t beat big retailers on catalog size; it wins on measurement-driven fit confidence and fewer returns.
