About
EyeNetra offers a comprehensive mobile refraction ecosystem built around three core devices: the Netra (auto-refractor), the Netrometer (auto-lensometer/focimeter), and the Netropter (phoropter/trial lens kit). Together these instruments collect the basic measurements required for glasses and contact lens prescriptions with clinical-grade precision—the autorefractor features built-in binocular accommodation control, the phoropter offers 0.25D steps for sphere and cylinder in a sub-1 lb form factor, and the lensometer neutralizes single vision, bifocals, and progressive lenses to 0.08D accuracy. The Mobile Refraction Kit bundles all three devices with a pre-configured smartphone and travel case, enabling pop-up clinics, workplace screenings, teleoptometry programs, and community vision events. An optional Online Portal centralizes scheduling, 21-point medical records, patient intake forms, e-prescriptions via SMS or email, and payment processing—all with unlimited cloud storage, free upgrades, and a full Open API for integrations. Originally a Boston-based startup, EyeNetra is now transitioning to an open-source project, making its vision-care technology freely available to developers and health innovators worldwide. With zero installation fees, 24/7 support, and deployment in 140+ countries, EyeNetra is ideal for NGOs, mobile clinics, occupational health programs, and any organization aiming to democratize access to eye care.
Key Features
- Portable Autorefractor (Netra): Smartphone-attached autorefractor with built-in binocular accommodation control for accurate, offline-capable refraction measurements anywhere.
- Handheld Phoropter (Netropter): Sub-1 lb digital phoropter offering 0.25D precision for sphere and cylinder adjustments, replacing bulky traditional trial lens kits.
- Digital Lensometer (Netrometer): Neutralizes single vision, bifocal, and progressive lenses in seconds with 0.08D precision, enabling rapid prescription verification in the field.
- Online Management Portal: Cloud-based platform for scheduling mobile events, storing 21-point medical records, filing e-prescriptions, accepting payments, and managing multiple refraction lanes.
- Open API & Open Source: Full REST API access and an open-source codebase allow developers and health innovators to build custom integrations and extend the platform freely.
Use Cases
- Mobile eye care clinics and pop-up refraction events in underserved or rural communities.
- Workplace vision screenings conducted on-site at corporate or industrial facilities.
- Teleoptometry and telemedicine programs requiring remote prescription collection.
- NGO and humanitarian health missions delivering vision care in developing regions.
- Open-source development of custom vision screening applications using the EyeNetra API and hardware platform.
Pros
- Truly Portable & Offline-Capable: The entire refraction kit fits in a travel case and works without an internet connection, making it ideal for rural outreach, disaster relief, and underserved communities.
- Open Source with No Licensing Fees: The transition to open source means builders and NGOs can access the technology without installation fees, with free software upgrades and unlimited cloud storage.
- Comprehensive All-in-One Kit: Combines autorefractor, lensometer, and phoropter in a single kit with a pre-configured smartphone, eliminating the need for multiple vendors or bulky equipment.
- Global Reach & Proven Deployment: Deployed in 140+ countries with 24/7 support and worldwide shipping, making it a trusted solution for international vision care programs.
Cons
- Requires Physical Hardware: Unlike purely software-based solutions, EyeNetra requires purchasing dedicated devices (Netra, Netrometer, Netropter), which involves upfront hardware costs.
- Niche Professional Use Case: The platform is designed specifically for eye care professionals and health organizations; it is not suited for general consumer self-testing.
- Smartphone Compatibility Constraints: Devices are calibrated for a specific smartphone bundled in the kit, which may limit flexibility for teams wanting to use their own hardware.
