For mobile eye diagnostics or vision screenings, the NETRA auto-refractor measures sphere, cylinder, axis and pupillary distance through a series of game-like interactions in a virtual-reality environment. It is binocular, portable and entirely patient-driven. There is no need for chin rest or forehead supports. It is the only portable autorefractor with a built-in fogging procedure to control for accommodation. With a solid body of 19 scientific papers, NETRA's accuracy is similar to state-of-the-art auto-refractors (~0.35D). There is no need for specialized furniture, dilation or cycloplegia.

The package includes:
  • 1 Netra Body (Automated Refractor)
  • 1 Calibrated Smartphone (EyeNetra applications pre-installed)
  • 1 Charger and Cable for the Smartphone.
