1.0.- About auto-brightness and change brightness prevention
- Summary: Settings -> General-> Accessibility -> Display Accomodation -> Switch off Auto-Brightness
For testing vision it is mandatory to switch off auto-brightness in order to maintain the background luminance constant for any environmental light used. The screen brightness can change if you put an App in second plane or if you put the iPad in the sleep mode. This can result in testing vision in different conditions of background brightness. However, from version 2.0 VisionC automatically detects when screen brightness has changed and modifies the brackground brightness to the stored in the App each time that you use the App for testing vision.
