LUVIS

"LUVIS" is the first worldwide lightbox for standardized and homogeneous illumination of the Pelli Robson contrast charts which are internationally used in numerous clinical studies. LUVIS was developed at the STZ eyetrial, department of ophthalmology at the university medical center in Tübingen. It fulfills the DIN ES ISO 8596, and therefore it can be ideally used for studies and vision tests according to the driving licence regulation (FeV).

LUVIS mini

With "LUVIS mini" you will get a lightbox for vision tests in small formats like the widespread MARS contrast chart. Compared to the big "LUVIS" the surface is illuminated by two LED modules. LUVIS mini is the perfect companion of industrial medics, optometrists and ophthalmologists who also perform mobile vision tests.

CORVINUS

Due to "CORVINUS contrast charts, vision contrast tests will get safer: Landolt rings reduce the guess probability, special lamination prevent reflection on the surface as well as permanent soiling. The print is carried out in full shades whereby higher edge sharpness of the optotypes is achieved.

information for patients

Contrast vision is a visual function, that many patients underestimate. Often it is even confused with other visual functions.

We, from the LUVIS team, want to change this! Since January 2017 we have launched a patient education flyer, which shall explain patients what contrast vision is, and why it is so important to have it tested. It is handed out at no charge through our customers, but it can also be viewed online here as a PDF:
