Netra by EyeNetra
The Netra refractometer measures sphere, cylinder, axis and pupillary distance through a series of game-like interactions in a virtual-reality environment. It's biocular, portable, and entirely patient-driven making it perfect for mobile screenings and baseline refractions in high-footfall areas. It's the only portable autorefractor with built-in fogging technology to control for accommodation. With a solid body of 19 scientific papers, Netra's accuracy is right up there with state-of-the-art autorefractors and aberrometers (~0.35D). There is no need for specialized furniture, power cords, dilation, and/or cycloplegia.
