What is the Dim Flashing Lights Accessibility feature?
Certain types of videos, often action-packed, contain rapid flashes of light called strobe effects. While it’s not a concern for some viewers, strobe light effects and flickering light can bother others.
Some films and TV series show a warning about strobing or flashing lights because it tends to bother people and trigger symptoms in others. For example, strobe light effects can cause people, like those with flicker vertigo, to become nauseous and disoriented. These may also induce a seizure in people predisposed to epilepsy and trigger a seizure in people suffering from the condition.
Dim Flashing Lights is a user-safety feature that automatically dims the video display when it detects flashes of light or strobe effects. If you or anyone you know is at risk of being triggered by these visual effects, you may want to turn on this feature.
