Flashing lights can trigger photosensitive epilepsy reactions in which frequency range?

Flashing lights can trigger photosensitive epilepsy reactions in which frequency range?

• A. 5-10 hertz
• B. 10-20 hertz
• C. 20-30 hertz
• D. 30-40 hertz

Answer: (B)

The frequency range that can trigger photosensitive epilepsy reactions is primarily within the 10-20 hertz range. This specific range is critical because studies have shown that visual stimuli, such as flashing lights, can induce seizures in individuals with this condition if the frequency falls into this interval. Flashing lights in this range can create a strobe effect that may cause abnormal electrical discharges in the brain, leading to seizures. The phenomenon is particularly prevalent in certain patterns and colors of light, and the 10-20 hertz range has been identified as a threshold that is most likely to induce such reactions. Awareness of this frequency is essential, especially in environments where flashing lights are common, ensuring proper safety measures are incorporated to protect those susceptible to photosensitive epilepsy.
