Research, Usability, Industrial Design, Engineering Development


NETRA™ is a portable, smart-phone powered, self-test refraction tool for use in mobile eye diagnostics and vision screenings. The NETRA™ auto-refractor, which is entirely patient driven, measures sphere, cylinder, axis and pupillary distance through a series of game-like interactions in a virtual-reality environment. NETRA's accuracy is similar to state-of-the-art auto-refractors used by Optometrists.


MANTA was responsible for human factors, industrial design and mechanical packaging of the device. Manta performed significant human factors research and testing to determine the optimal device shape and control positioning. Our mechanical engineering team took responsibility for the detail design of the device enclosures and interface elements.
