LED light can damage eyes, French health authority warns
f.lux author here. I'm pasting parts of the 458 page PDF into Google Translate.The recommendations look very good, and don't particularly match the Yahoo article.1. They recommend IEEE 1789 as a flicker standard for Europe, which is fantastic, as it covers lower levels of stroboscopic flicker that other standards have missed. (e.g., typical 120Hz flicker from direct-wire TLEDs)2. They re-state the "acute" hazard from extremely bright LEDs, while urging some caution on "chronic exposure" to lower light levels. Suggest that some automotive lights could be a problem since they have high luminance. Urge more research on progression of macular degeneration and chronic exposure. The question about acute levels refers to a paper by Hunter [2012]. Nobody is saying that screens or residential lights pose a new problem.3. Circadian recommendations are solid - more light during the day, and reduce light around 480nm at night. Pregnant women and children may have lower thresholds.4. Say most ophthalmic lenses filtering blue light don't do very much, and specialized ones (you'd say very orange or red) are required for circadian effects.
