Dim Flashing Lights

Dim Flashing Lights is a setting that allows people to indicate that they want to avoid bright, frequent flashes of light in video. When someone enables this setting on an Apple device, the device automatically dims video when flashes or strobe effects are detected. Use the Media Accessibility API to check if someone has chosen to dim flashing lights on their Apple device. If you work with media content outside of Apple platforms, learn about the science behind reducing flashing lights in video content to create an enjoyable media-viewing experience for everyone.
