Positive experience for subjective refraction

Almost two-thirds of people in Germany wear glasses. Just over one-third of them wear glasses at all times. Therefore, many patients are familiar with the long and challenging vision test, during which the eye chart and phoropter are used. For the next generation of devices, Intuity has come up with an interaction and user interface design that supports the working procedure of opticians and ophthalmologists.

The new eye chart and refractor are controlled simultaneously via an tablet pc, allowing the patient, optometrist or ophthalmologist to enjoy the benefits of comfort, speed and precision – and leaving more time for individual consultation.

Both eye chart and refractor are linked with each other and with a database. The patient’s data is stored here. The same applies to other ZEISS equipment for subjective and objective refraction (autorefractor, wavefront measuring device, lensmeter), intraocular pressure testing, and slit lamp examination. This connectivity – as a concrete example – created the foundation for fundamental transformations in business models in the medical industry. Read more: “Convergence of business models”

The project involved visual & interaction designers, creative technologists, product managers and technical experts. Intuity developed the design strategy, interactive prototypes and programmed the front-end. The ZEISS team came up with the industrial design vision, implemented the design and programmed the back-end. Both teams worked very closely together on site and supported user tests.

ZEISS and Intuity fulfilled the industry standards for safety, operation, precision and materiality.

We used our 12 principles for Lean User Experience Design both for this project, as well as in our work for the VISUPLAN 500 and the redesign of iTerminal from ZEISS. Read more: “How to get it lean and more successful?”
