The sensor at the top of the left lens of your glasses takes into account the light around you to adjust the lighting of the screen. You can turn this feature on or off in the Cosmo app.
If the auto-brightness behaves abnormally (screen flickering, static brightness...)
Try disabling and re-enabling it in the "Configuration" tab of your Cosmo Vision (accessible from the "My Cosmo" menu).Also try turning the glasses off and on.If necessary, try closing the Cosmo Connected application and opening it again, then repeat the previous steps.
If the problem persists, please contact Cosmo Connected customer service(support@cosmoconnected.com).
