Follow doing to learn how to automatically dim flashing lights in video content in iOS 16.4/iPadOS 16.4 or later.

Automatically Dim Video on iPhone and iPad When Flashes of Light are Detected 

Before moving ahead, let’s break down this latest feature and its significance! 

Why do you need to lower the brightness of the video when flashes of light are detected?

Introduced as part of the Accessibility suite, the “Dim Flashing Lights” is specifically designed for people who have photo-sensitive epilepsy.

For those uninitiated, seizures in photosensitive people tend to get triggered by contrasting light and dark patterns, flashing lights/stroboscopic effects, and rapidly alternating patterns of different colors. Moreover, these effects have also been found to produce harmful sensations.

Even though photosensitivity epilepsy is not common, it might be diagnosed when you have an EEG (stands for electroencephalogram) test which is basically a recording of brain activity. Using the tiny sensors attached to the scalp, the EEG test retrieves the electrical signals produced by the brain. 

Developed keeping in mind user safety, this Accessibility feature automatically reduces the brightness of video content that depicts triggering light effects in order to safeguard the vision.
