Basic concept

«Objective information about viewing distances helps to understand behavior patterns.»

Viewing distances during daily activities

Vivior’s solution combines data from behavioral information with objective measurements via a dedicated device, worn during a testing period. This combination of data enables eye care professionals to offer optimal personalized solutions to their patients.

Distribution of visual distance

The distribution of visual distance can be shown in an overview graph.

Vivior Basic Concept

Objective patient data lead to the most suitable therapy

Objective information about viewing distances during daily activities, e.g. working on a computer, helps to understand behavior patterns. Eye care professionals currently rely on interviews without data from objective measurements in planning the refractive target for their procedures, which can lead to unsatisfactory outcomes. Vivior’s service will lead to active engagement and therefore to a higher conversion rate to premium solutions, e.g. multifocal intraocular lenses or high-end progressive spectacles.

Example of a distribution of typical vision

Example shows the distribution of typical vision needs in the office. Measurements can be mapped on two-dimensional distribution of viewing distances.

The Visual Behavior Monitor

Our Visual Behavior Monitor 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 and the data is uploaded to the cloud for processing and analysis.
