What OUI does
OUI Inc. is a Tokyo-based, Keio University School of Medicine spin-out founded in 2016 by practicing ophthalmologist Eisuke Shimizu (MD, PhD) to address preventable blindness in low-resource and remote settings. The company's core product is the Smart Eye Camera (SEC), a smartphone-attachment medical device that converts a smartphone camera into a portable slit-lamp microscope or ophthalmoscope, manufactured via high-precision 3D printing and requiring no battery or charging. SEC is paired with dedicated iOS applications for image capture, filing and telemedicine, and incorporates proprietary AI algorithms for nuclear cataract diagnosis (published in Scientific Reports 2023), dry eye detection, and anterior chamber depth estimation for glaucoma risk. The company also operates Mobile Eye Scan (MES), a corporate visiting eye examination service, and +Eye Dr., a remote ophthalmology image reading service.
OUI generates revenue through three streams: hardware sales of the SEC device to clinics, hospitals and individual practitioners (including via App Store distribution), corporate eye examination services delivered through partnerships such as Dai-ichi Life Insurance (effective April 2026), and recurring remote image-reading subscriptions. The company monetizes across three customer segments: corporate employers seeking presenteeism reduction, healthcare providers in underserved and rural areas (domestic and international), and international development organizations including IAPB, IDB Lab and ADB. Distribution combines direct enterprise sales, channel partnerships with insurance carriers, and international development procurement channels. Granted patents cover Japan, USA, EU, China, India, Vietnam, Malawi and ARIPO jurisdictions, and SEC is the only Japanese device in the WHO Compendium of Innovative Health Technologies for Low-Resource Settings 2024.

OUI competitors and assessment
Company assessmentBroad incumbents
- Topcon Corporation: Global incumbent in ophthalmic and optometric equipment (slit lamps, fundus cameras, OCT). Comparable because Topcon sells the traditional diagnostic devices that Smart Eye Camera is positioned against as a portable, lower-cost alternative.
- Nidek Co., Ltd. Established Japanese manufacturer of ophthalmic and optometric equipment including slit lamps and fundus cameras. Directly comparable as a Japan-based maker of the traditional eye-examination devices SEC aims to supplement or replace in low-resource settings.
- Carl Zeiss Meditec: Premium global ophthalmic device maker (slit lamps, OCT, surgical microscopes). Comparable as a high-end incumbent whose installed base defines the clinical standard OUI must meet or differentiate against.
Direct peers
- Remidio Innovative Solutions: India-based maker of smartphone-based fundus cameras and AI screening tools for diabetic retinopathy and other eye diseases. Closely comparable: portable, smartphone-attached ophthalmic hardware plus AI, targeting underserved populations and tele-ophthalmology.
- Optomed: Finland-based maker of handheld fundus cameras and screening solutions with AI software for retinal screening. Comparable as a portable, AI-enabled eye-screening hardware+software vendor competing for similar tele-ophthalmology and primary-care customers.
- Phelcom Technologies: Brazilian startup building smartphone-based retinal imaging devices (Eyer) with AI screening, active in Latin America. Comparable: portable smartphone ophthalmoscope + AI serving emerging markets including Brazil, where OUI also has an IDB-backed project.
- Forus Health: India-based maker of portable, low-cost ophthalmic screening devices (3nethra series). Comparable as a portable pre-screening ophthalmic device targeting primary care and developing-country eye-health programs, similar to OUI's emerging-market use cases.
- D-EYE: US/Italy-based developer of a smartphone ophthalmoscope attachment for retinal screening and telemedicine. Closely comparable product form factor (smartphone-attached fundus camera) and telehealth use cases.
Emerging players
- Mediwhale: South Korean AI health-screening company using retinal imaging for systemic disease risk prediction. Comparable through the AI-on-retinal-imaging angle that OUI's anterior-segment AI work parallels, though focused on systemic rather than ocular disease.
Regional players
- Aurolab (Aravind Eye Care System): Manufacturing arm of India's Aravind Eye Care System, producing low-cost ophthalmic devices and consumables for developing countries. Comparable mission (low-cost eye care for underserved populations); listed as an OUI partner, but also a potential peer in portable ophthalmic device manufacturing.
