NETRA is a companion app for the NETRA Autorefractor
add-on for Samsung S4s. Please see more information here: https://eyenetra.com/product-netra.html
Ideal for mobile eye clinics and vision screenings, the NETRA autorefractor measures the eye's refractive error for eyeglasses prescriptions. The user goes through a series of game-like interactions in a virtual-reality environment. In the end, the smartphone computes sphere, cylinder, axis and pupillary distance.
The NETRA app connects the device results to the Insight platform: an on-line, HIPAA-compliant EMR. Insight provides all the necessary tools to allow eye care providers to perform refractions anywhere.
