Diese Anwendung gibt Optikern die Möglichkeit aus den attraktivsten Produktpaletten von Brillengläsern ein persönliches Angebot für ihre Kunden zu ermitteln. Die komplexe Zuordnung von passenden Glas-Eigenschaften (welche Entspiegelungen, welche Farbkombinationen und Bestelloptionen...) wird ihnen dabei vollständig von der prisma.app abgenommen und sie können sich somit ganz der Kundenberatung widmen. Verschiedene Angebote lassen sich in Karteiform zu besseren Vergleichbarkeit für einen kurzen Zeitraum speichern, für Nutzer unserer PRISMA Augenoptik Software auch dauerhaft in ihrer eigenen Kundenverwaltung.
