For mobile eye diagnostics or vision screenings, the NETRA autorefractor measures sphere, cylinder, axis and pupillary distance through game-like interactions in a VR setting. The binocular, patient-driven exam takes about 2 minutes. NETRA is the only mobile autorefractor with built-in accommodation control. With 20+ scientific papers, NETRA's accuracy is proven to be the same as other state-of-the-art autorefractors (~0.35D). No need for dilation or cycloplegia.

The package includes:
  • 1 Netra Body (Automated Refractor)
  • 1 Calibrated Smartphone (EyeNetra apps pre-installed)
