Vision-related problems are common.

  • 56% vision-related problems (e.g. headaches or tired eyes) of all patients aged between 18 and 38 years n= 1679 in five vision centers (Montés-Micó, 2001).
  • 46% asthenopic problems in computer users n= 419 (Bhanderi, Choudhary, & Doshi, 2008).

Classification allows a targeted approach to solving the problems.

  • 32% can potentially benefit from the classification
    (García-Muñoz, Carbonell-Bonete, Cantó-Cerdán, & Cacho-Martínez, 2016), and (Hussaindeen et al., 2017).


Easy to get started with the minimal test battery (3 tests)

Detect vision problems and their causes quickly and easily: With just three measurements, it is possible to determine very specifically whether binocular vision or accommodation is abnormal. The BTSO learning app shows how a classification is made.

Schoolchildren can also be quickly screened for vision problems using the minimal test battery.

Minimum Testbattery with:

Features

  • Quick and easy. The test sequence takes max. 7 minutes, the evaluation 1-2 minutes.
  • Can be used during the eye test or in quick mode after the eye test.
  • Can be used from school age. User guidance through all steps of the measurements with information displays.
  • Evaluation graphic to make all parameters visible at a glance and to show whether they are within the normal range or not based on their position.
