How to Automatically Dim Flashing Lights on iPhone or iPad


For anyone who is sensitive to flashing lights, such as people who live with epilepsy, there’s nothing scarier than being caught off guard by video content with flashing or strobing lights, which can induce seizures. As a result, as part of its latest update, Apple is adding functionality that can automatically detect flashing or strobing lights in videos, and then dim those lights to reduce the risk of an incident. This feature isn’t enabled by default, and you do have to turn it on.

Reasons to Consider Automatically Dimming Flashing or Strobing Lights on Your iPhone or iPad

1. Protecting Photosensitive Individuals

People with photosensitive epilepsy or migraine are at risk when exposed to flashing lights. These lights may trigger seizures or severe headaches, creating a dangerous situation. By dimming these lights, we can make videos safer and more enjoyable for everyone, ensuring a more inclusive digital environment.

2. Enhancing Visual Comfort

Watching videos with flashing or strobing lights can be uncomfortable, even painful. This discomfort often leads to eye strain and annoyance. Dimming these lights can significantly improve visual comfort, making your video-watching experience more enjoyable and relaxing.

3. Improving Accessibility

People with sensory processing disorders or visual impairments may find it difficult to watch videos with flashing lights. Dimming these lights can make videos more accessible and enjoyable for a wider range of viewers, promoting inclusivity and equal access to digital content.

4. Promoting Sleep Hygiene

Exposure to bright or flashing lights, particularly blue light, can disrupt sleep patterns. Dimming these lights on your iPhone or iPad helps maintain a healthier sleep environment by reducing the impact on your body’s natural sleep rhythms. This simple adjustment can lead to better sleep and overall well-being.

5. Focusing on Content

Flashing or strobing lights can distract viewers from the main content of a video. By dimming these lights on your iPhone or iPad, the focus shifts back to the important aspects of the video, providing a more engaging and immersive experience.

6. Catering to Aesthetic Preferences

Some viewers simply prefer videos with dimmed flashing or strobing lights for personal reasons. Respecting these preferences and offering the option to dim lights can enhance the overall viewing experience and cater to diverse tastes.

7. Being Considerate in Public Settings

In public spaces or shared environments, flashing lights in videos may disturb others. Dimming these lights demonstrates consideration for those around you, fostering a more pleasant atmosphere and promoting good etiquette.
