The fluorophore will fluoresce when it binds to glucose. The amount of fluorescence directly corresponds to the amount of glucose in the interstitial fluid. If ambient light (like sunlight) is high enough to interfere with measuring that fluorescence, the system will display a High Ambient Light Alert. No glucose will be displayed until the condition is resolved by reducing the ambient light condition.
