![]() ![]() Guns, explosions, cannons, and other weapons flash when used, so make sure to check for scenes like this in videos. At the time I thought it was just because of the blood in the movie. While I didn’t realize it at the time, I ended up feeling very disoriented and felt sick. This created a large amount of flashing lights. ![]() When I was in seventh grade, my class watched a movie that featured several gunshots, bombs, and similar weapons being discharged rapidly. ![]() These may be very obvious or hidden in the background, but making a note of flashing background scenes is an easy way to ensure that every scene is accounted for. Many movies that feature scenes with police cars in the background, nightclubs, or concerts have blue, white, and red flashing lights going off in the background. I also would ask about fireworks, though those are less common. After that, I started asking specifically if there was lightning in any of the videos we would be watching. I ended up in the nurse’s office not too long after a lightning storm came up. Unfortunately, they didn’t realize that flashes of lightning are the equivalent of nature’s strobe lights. I was watching a video in one of my classes that my teacher said they had checked beforehand. While this trigger may only be relevant for people with severe sensitivities to flashing lights, it’s still important to note and can be remedied by showing the highest resolution video available. As recording and audiovisual technology has improved over time, so has the clarity of videos, which dramatically reduces the potential issues mentioned above. Many black-and-white videos contain floaters and changing lighting conditions that resemble flickers of light, especially in historical videos like those found in archives. Outside of obvious triggers like full screen strobe lights and rave scenes, here are some less obvious sources of flashing lights in video content that can trigger an adverse reaction. Adapting Band Uniforms For Photosensitivity and Sensory Overload.Flashing Lights and Photosensitivity in the Classroom.I am not advocating for the removal of flashing and strobe lights from existence, I am sharing how I personally avoid a known medical trigger for me and how I ask people close to me to help me in doing so. Some people with epilepsy, PTSD, ADHD, autism, and other photosensitive conditions may experience adverse health effects due to flashing lights. Migraines aren’t the only condition that can be triggered by strobe lights though. I now find that I am especially sensitive to white, red, and blue lights that flash or strobe quickly. My condition has changed over time though, and so have my triggers. I have a brain condition called Chiari Malformation that causes me to have many neurological symptoms, with one of them being photosensitivity and chronic migraines triggered by flashing lights. I have dealt with this issue since ninth grade and at one point I was so sensitive that even small amounts of flashing lights could be a problem. Today, I will be sharing how to check videos for flashing lights to see if they could trigger an adverse medical reaction such as a seizure, migraine, or vertigo. ![]() Luckily, I have had many awesome friends and teachers who check videos for me ahead of time to ensure that I don’t get any migraines from whatever we are watching. This can seem like a question that is nearly impossible to answer, since flashing and strobe lights seem to be everywhere- the lights on a school bus, the fire alarm, and even camera flashes can be disorienting to someone who is photosensitive. Before I watch videos, I have to check with someone to see if the video contains any flashing or strobe lights. ![]()
