Essentially, a digital video centration system performs the basic measurements, such as pupillary distance, segment height for progressive lenses, vertex distance, panoramic angle, and pantoscopic tilt. A digital photo function is also included for capturing how the consumer looks wearing the spectacles.
While the refraction position is the matching of the prescription with the consumers’ visual needs, the visuReal system provides a set of measurements that allow the laboratory to make alterations to the lens design to match the consumer’s prescription needs for maximizing visual quality.
