Device for Testing Mesopic Vision and Glare

Tests of mesopic vision and glare sensitivity are important supplements to photopic vision testing, especially when night driving capacity must be assessed. If the patient has IOL implants or or has undergone refractive surgery, it is advisable to check mesopic vision and glare sensitivity both pre- and postoperatively as well as before prescribing tinted lenses.

Free Space

Tests are carried out under normal visual conditions  without occurrence of instrument myopia. The unit is designed such that results remain unbiased by
interpupillary distance.


Pulse motors control test sequences quickly and with pinpoint precision.

Easy to Use

The examination program is run at the touch of a key. The instrument is compact in design; no switching of test discs is necessary.


Programmed control of test runs eliminates user errors.


Measurements can even be taken in brightly lit rooms.


The compact device only weighs 7.8 kg; an optional carrying case makes for easy transport.

Data Transfer

The software module allows you to perform Mesotest II exams from a PC. Data can be transferred to EDP systems in medical practices.
