The Virginia Poison Center warns that certain medications can increase skin sensitivity to UV rays and heat, leading to symptoms like nausea, dizziness, and skin rash, especially during hot weather. People are advised to use sunscreen, wear protective clothing, stay hydrated, and be aware of medication side effects to prevent heat exhaustion.
Researchers from the University of Glasgow and University of Birmingham have developed a prototype liquid crystal lens that can block over 98% of light in the 660–720nm wavelength range, which is known to trigger seizures in people with photosensitive epilepsy. The lenses are controlled by small temperature changes and can be integrated into glasses, potentially helping patients avoid seizures in environments with triggering light, such as while watching TV or playing video games. Further development is needed to enhance performance and adapt to different temperatures.
The Apple Vision Pro's use of Pulse Width Modulation to regulate brightness and color mix may pose health risks for some users, including motion sickness and potential issues related to constant flashing. Strobing lights can trigger flicker vertigo, photosensitive epilepsy, and aggravate other health conditions such as migraines and traumatic brain injuries. The device's design, which covers the user's entire field of vision, increases the impact of the strobing. Users experiencing any unusual symptoms are advised to stop using the device and consult a doctor, while caution is urged for new owners to avoid excessive use.
Electronic Arts (EA) is expanding its accessibility toolset by patenting IRIS, a photosensitivity tool that analyzes and identifies frames that could trigger epileptic episodes. The tool provides easy-to-understand analytics for developers to quickly check their content for flashing lights or rapidly changing spatial patterns. EA has already implemented IRIS in select games and plans to incorporate it into more titles in the future. In an effort to create a more inclusive gaming experience, EA is open-sourcing IRIS and other patented technology to help players with disabilities have a smoother game experience.
