Vivior provides a service for all customers and patients that require a solution to improve their vision. Our objective behavioral data supports experts like ophthalmic surgeons, optometrists, opticians and others to offer personalized solutions to their customers and patients. The specific solution - be it an intraocular lens for cataract patients, laser eye surgery or progressive spectacle lenses - will be customized to the customer's and patient's lifestyle and visual needs.Our Vision Behaviour Monitor (VBM) consists of sensors measuring distance, ambient light and color, an accelerometer, a gyroscope and a magnetometer with a low-energy Bluetooth interface. It is worn on prescription or clear glasses; measurements are monitored and recorded on a paired wrist-worn smartwatch or smartphone. Subsequently, the data is uploaded to the cloud for processing and analysis. Vivior has assembled a world-class team supported by a Medical Advisory Board consisting of renowned surgeons from the US and Europe. Relevant IP has been filed, proof-of-concept achieved and prototype devices have been tested.
