Some devices have unintentionally demonstrated how the infrared sensing used in night vision goggles and thermal cameras can reveal the unseen, like the OnePlus 8 Pro’s “Photochrom” color filter that worked like X-ray vision on the thin shell of an Apple TV. When used on people, infrared photography can reveal the lines of a person’s body or the undergarments they’re wearing beneath a thin layer of clothing, such as those worn by athletes.

In 2020, athletes complained to the Japanese Olympic Committee after discovering infrared camera “photos of themselves shared on social media with sexually explicit captions,” according to The Japan Times. Since then, Mizuno, Sumitomo Metal Mining, and Kyodo Printing have co-developed the new fabric that’s stretchable enough to be used in athletic uniforms while also protecting athletes.

Kinda sounds like they’re doing it because people are fucking creeps who don’t mind brushing up against the boundary of involuntary pornography
