All of this screen time comes with a price: high-energy blue light, found in standard liquid crystal displays (LCD) and LED screens, is potentially harmful when emitted into the eyes for hours at a time. Blue light poses a hazard to retinal cells in the eye, and exposure to blue light near bedtime reduces levels of the sleep-inducing hormone melatonin, disrupting the circadian rhythm and restorative sleep. The key takeaways from the Harvard study include:\n<\/p>\n<ul class=\"bwlistdisc\">\n<li>\nSpectra of light from displays is a leading trigger for stress on retinal cells.\n<\/li>\n<li>\nRetinal cells stressed by blue light produce \u201creactive oxidative species\u201d (ROS), which can accumulate during prolonged times of viewing, thereby leading to photo-oxidative retinal damage.\n<\/li>\n<li>\nDevices including E Ink\u2019s ComfortGaze\u2122 front light were up to three times less stressful for retinal cells than LCD devices.\n<\/li>\n<li>\nColor temperature settings can impact stress levels on retinal cells, but LCD color adjustments to day or night mode are less effective than using lighting solutions with spectra engineered for eye safety.\n<\/li>\n<li>\nE Ink devices without a front light do not emit any blue light to stress retinal cells.\n<\/li>\n<\/ul>\n<p>\n\u201cExisting recommendations for blue light safety of displays are based on the spectrum of the light they emit. This study sought to measure the actual response of retinal cells when exposed to commercially available displays,\u201d said Dr. Rick Rogers, Principal Research Scientist of the BioMedical Imaging Laboratory, T. H. Chan Harvard School of Public Health, now the Director of Research at the BioInnovations Institute, Natick, MA.\n<\/p>\n<p>\nThe study compared two different kinds of displays: LCDs and ePaper displays with front lights. LCDs and ePaper have a key difference in the manner they use light. In order to view an image on an LCD screen, the displays use a backlight, usually LED based, to push light through the LCD material. In contrast, E Ink\u2019s ePaper displays are just like paper: they do not emit any light. Instead, they reflect the ambient light to illuminate the display. In dim or dark situations, when there is not enough light for reading, ePaper displays employ front lights, which perform the role of a built-in booklight.\n<\/p>\n<p>\nIn the study, ePaper devices were tested with different types of front lights: a cold-white, a warm-amber, and the new E Ink ComfortGaze\u2122 front light. ComfortGaze\u2122 was engineered to reduce the amount of blue light reflected off the surface of the display, providing further comfort while reading with a lower blue light spectral output and a light output that is less amber in hue.\n<\/p>\n<p>\nThe study found significant differences between the \u201ccolor temperature\u201d of the LEDs being used, with \u201ccool\u201d daylight mode having a blueish-white, and \u201cwarm\u201d nightlight mode having an amber appearance. The exception was ComfortGaze\u2122, which reduces hazardous blue light output without creating an amber-white tint in nightlight mode. Devices with E Ink ComfortGaze\u2122 in warm-white mode can be used three times as long as an LCD in cold-white mode, and twice as long as that same LCD in warm-white mode, before reaching the same level of ROS stress in retinal cells (as LCDs).\n<\/p>\n<p>\nePaper displays without front lights show advantages even when compared to print paper. Bright white paper contains fluorescent brighteners, which are not contained in E Ink displays. These brighteners produce not only the clean blueish brilliant white of print paper, but also increase blue light reflection. In other words, E Ink displays can be considered safer for your eyes than print paper.\n<\/p>\n<p>\n\u201cIn today\u2019s digitally connected world, it\u2019s often difficult to reduce the amount of time spent using screens, but not all displays are built the same,\u201d said Lynne Garone, Associate Vice President of E Ink. \u201cParents are increasingly worried about the time their children spend both in school and in leisure using displays. Shifting a portion of screen time to a healthier display for reading and writing allows us to remain connected without sacrificing eye health.\u201d\n<\/p>\n<p>\nIn addition to the work on Blue Light research, E Ink has also been studying the CO2 effects of displays using paper or LCD versus ePaper displays. Findings have shown significant CO2 savings with the use of E Ink ePaper displays.\n<\/p>\n<ul class=\"bwlistdisc\">\n<li>\nAs an example, a financial institution with 125 branches saves 16.5 million A4-sized paper sheets each year when they adopt an eNote using E Ink\u2019s technology, and contributes approximately 1,100 tons of CO2 reduction each year.\n<\/li>\n<li>\nIn the past five years, 130 million eReaders have been in use globally, replacing the purchase of paper editions of books. It is estimated that paper books would emit more than 100,000 times the CO2 versus eReaders with an E Ink display and LCD devices would emit more than 50 times the CO2 versus eReaders throughout that time.\n<\/li>\n<li>\nOver the past seven years, 600 million electronic shelf labels (ESLs) of around three inches in size have been installed worldwide. If it is assumed that the price and information is changed four times a day, ePaper tags can reduce CO2 emissions by 32,000 times versus single-use paper price tags.\n<\/li>\n<li>\nComparing the energy usage of ePaper retail tags versus LCD retail tags over a period of five years, with four updates per day, for every kilowatt hour (KWh) consumed to manufacture the ePaper material a savings of 400 KWh is realized.\n<\/li>\n<li>\nE Ink\u2019s low power ePaper enables solar-powered ePaper signage and bus stops around the world to be net-zero devices, using 100 percent renewable energy.\n<\/li>\n<\/ul>\n<p>\nFull details of the study can be found at the Journal for the Society of Information Display: <a target=\"_blank\" href=\"https:\/\/cts.businesswire.com\/ct\/CT?id=smartlink&amp;url=http%3A%2F%2Fdoi.org%2F10.1002%2Fjsid.1191&amp;esheet=53360253&amp;newsitemid=20230313005152&amp;lan=en-US&amp;anchor=http%3A%2F%2Fdoi.org%2F10.1002%2Fjsid.1191&amp;index=3&amp;md5=ed2384c79eb42219786270ad0ef94835\" rel=\"nofollow noopener\" shape=\"rect\">http:\/\/doi.org\/10.1002\/jsid.1191<\/a>.\n<\/p>\n<p>\n<b>About E Ink<\/b>\n<\/p>\n<p>\nE Ink Holdings Inc.
