In iOS 16.4 and iPad 16.4, Apple has added an accessibility option that dims video when flashes of light or strobe effects are detected. Here's how to enable the feature on your device.
When watching video on your iPhone or iPad, there may be times when the content includes rapid flashes of light or stroboscopic effects. In such cases, a key concern is user safety.
Some people with photo-sensitive epilepsy can be affected by strobing light, which may induce seizure. The effect can also produce undesirable sensations amongst the general population, such as disturbed vision.
With this in mind, Apple has added a new option in its accessibility feature set that can automatically reduce the brightness of video if it includes triggering light effects.
The following steps show you how to enable the feature. Note that you must have iOS 16.4 or iPadOS 16.4 installed on your device to see the option. You can check that your device is up-to-date by going to Settings -> General -> Software Update.
- Open the Settings app.
- Scroll down the menu and tap Accessibility.
- Under the "Vision" section, tap Motion.
- Toggle the switch next to Dim Flashing Lights to the green ON position.
That's all there is to it. Next time you play video and iOS detects the lighting effects, the screen will be automatically dimmed to reduce the possibility of a negative reaction.
