It's not especially rare to come across flickering lights and stroboscopic effects in videos, and although these can be bothersome for many individuals, flashing lights may pose a particular challenge for people with epilepsy.
Thankfully, the most recent iterations of MacOS provide a feature that detects flashing and stroboscopic lights in videos and dims them automatically. This serves as an excellent accessibility tool, regardless of whether you're just irritated by the flashing lights or if they might lead to health issues.
How to Automatically Dim Flashing Lights / Strobing in Videos on Mac
To use this feature, you'll need MacOS Ventura 13.3 or a later version since older versions don't support it.
Navigate to the ? Apple menu and select “System Settings.”
Locate Accessibility in the sidebar menu.
Proceed to “Vision,” followed by “Display.”
Turn the switch for “Dim Flashing Lights” to the ON position.
Close the System Settings window.
With this feature activated, the toggle indicates that "video content showing repeated flashing lights or stroboscopic effects will be automatically dimmed."
Since this is a system-wide setting, the adjustment will apply to all Mac applications, including your default web browser and other areas.
Should you decide this setting isn't needed, you can revert it by switching the "Dim Flashing Lights" toggle back to the OFF position, which is the default setting on macOS.
A comparable option is available for iPhone and iPad users who are also affected by flashing lights or stroboscopic effects in videos on those devices.
