![]() ![]() Truth in Television, but only for people with photosensitive epilepsy. This is a common feature of the Phonýmon trope. See also Brown Note, Red Alert, Technicolor Death, Stop Motion Lighting, Blinding Camera Flash, and Throat Light. Compare to Power Glows, where light produces a positive effect, and Glowing Eyes of Doom, which implies imminent evil rather than imminent (self)destruction. Not in any way related to Epileptic Trees, and only tangentially related to Strobing. Older video games in particular often employed flashing screen effects because color-cycling demands so little processing power since advances in graphic technology have discredited this excuse, toning down flashing lights or patterns that could trigger seizures has become one of the few alterations routinely made to classic games in official emulated re-releases such as on the Virtual Console. Also contributing to this is that flashing tends to be one of the easiest visual effects to achieve. Many film and video game creators believe that everything is better with flashing, even though it's not always that awesome. Works which are intended to be disorienting and/or were made for the art are especially prone to this, as are (more contemporary) horror and science fiction genres. Intense flashing effects are generally more common in older works, due to society becoming more concerned about this trope over time. Justified in failing lightbulbs and warning lamps, but may otherwise lead to moments of failed awesomeness. Fisher is the Maslah Saul MD Professor of Neurology at the Stanford University School of Medicine in Palo Alto, CA, and director of the Stanford Epilepsy Center.It seems that whenever something or someone goes haywire, fails or is about to explode, light is going to flash rapidly, randomly and brightly, whether it originates from buttons, lamps, screens or even eyes and orifices. For example, warnings about the potential for seizures have been added to many video games, and flashing emergency lights can flash only once every two seconds, a frequency below the number needed to trigger a seizure.ĭr. ![]() Recently, efforts have been made to reduce the risk of a seizure for people with photo-sensitive epilepsy. Consider wearing nonglare glasses, and take frequent breaks. Using a computer: Use a flicker-free monitor (LCD display or flat screen) and a glare guard. Cover one eye while playing, alternating which eye is covered, and remember to turn off the game if strange or unusual feelings or body jerks develop. Do not close and open eyes while looking at the screen blinking can trigger a seizure. Take frequent breaks from the games and look away from the screen every once in a while. Playing video games: Sit at least two feet from the screen in a well-lit room and reduce the brightness of the screen. If necessary, wear polarized sunglasses to reduce glare. Avoid watching the monitor for long periods of time. Watching TV: Watch in a well-lit room to reduce the contrast between light from the set and light in the room and sit as far back from the screen as possible. Stripes of contrasting colors and flashing lights on tops of buses or emergency vehicles are other triggers. Natural light, such as sunlight, especially when shimmering off water or flickering through trees or through the slats of window blinds, can also trigger seizures in some people. Other triggers include flickering or rolling images on a TV screen or computer monitor, video games or TV broadcasts containing rapid flashes or alternating patterns of different colors, and intense strobe lights like visual fire alarms. Other Light TriggersĪ flashing light is just one potential trigger. If they see an electrical buildup on the monitor they know to turn off the lights. Technicians usually alert patients about the potential for a reaction and monitor for it. As part of a routine EEG, a strobe light flashes at different frequencies while a technician monitors the recording. Most people who've been diagnosed with epilepsy undergo an electroencephalogram (EEG), which has its own flashing light. Many people are unaware of a sensitivity to flickering lights or certain patterns until they have a seizure. Due to a condition called photosensitive epilepsy, lights can trigger seizures in one in 10,000 adults and one in 4,000 children and adolescents. Fisher, MD, PhD, FAAN, responds:įor about 3 percent of people with epilepsy, exposure to flashing lights at certain intensities or certain visual patterns can trigger seizures, according to the Epilepsy Foundation.
