 | Controlling and result-storage from PC/Laptop or from standard console or comfort console |
 | Micro-processor controlled test sequence, also individually programmable |
 | Valid visual acuity measurement using standardized optotypes (Landolt ring and correlated letters) and standardized viewing conditions: DIN 58220/ISO 8596 |
 | Examination of the binocular functions: fixation disparity and quantitative stereopsis |
 | Screening of colour vision |
 | Wide viewing windows, independent of subject‘s P.D. |
 | Optical principle ensures the natural status of the accommodation/ convergence realationship; the simulated free-space viewing conditions induce no instrument myopia or proximal convergence: the vision test is performed in a “natural” visual state |
 | Continuously variable adjustment of the examination distance from 33cm to infinity (no additional test disc and no special or extra optical components are necessary) |
 | The adjustable angle of viewing enables comfortable examination of bifocal and progressive lens wearers |
 | External interface RS 232C |
