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 2-3 minutes. NETRA is the only mobile autorefractor with built-in accommodation control and can be used as an enhanced vision screener or as an autorefractor for mobile/concierge optometrists. 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:
