Oyster, an ebook subscription service, has released a new feature on its mobile app to adjust light levels and help improve sleep, as reported by The Verge.
Ebook subscription service Oyster certainly thinks so, and has released a new feature for its mobile apps named Lumin, which automatically adjusts your device’s light levels based on the time of day. The result, they say, is better sleep and less eye strain — good news for habitual late-night readers.
Like the popular desktop software Flux, Lumin doesn’t just dim a user’s screen, but instead reduces the amount of blue light it’s emitting. Scientists have suggested that these shorter wavelengths of light are more disruptive to our sleep than incandescent lighting (or no light at all of course), as they suppress the body’s production of the sleep hormone melatonin.
