The Science Behind Why E Ink Screens Are Better for Your Eye Health and Wellness

May has been designated as Healthy Vision Month by the National Eye Institute (NEI) to spotlight the importance of eye health. In this screen-saturated age, digital eye strain has become an increasingly common issue. Globally, the average person spends over 7 hours looking at screens each day, be it for work, study, or entertainment. Such extensive screen time has also raised concerns about its impact on vision health and overall well-being.

According to a study conducted by the Harvard School of Public Health, displays with harsh blue light such as smartphones, tablets, and computers cause greater stress on retinal cells, and in comparison, E Ink's ePaper devices are up to three times healthier for eyes than LCD screens. Let's see why ePaper is a healthier alternative and how you can build healthier screen habits.

Why ePaper Is Better for Your Eyes

Reflective Display: A Paper-Like Experience

E Ink, or ePaper devices employ a reflective display technology that mimics the appearance of ink on paper. Unlike LCDs and LEDs, which shine light directly into your eyes via a backlight, E Ink screens rely on ambient light for viewing, requiring no internal light source. When there is little light around you, front lights can provide illumination. They are angled down the surface of the display, and the light you perceive is reflected from the screen, which creates a natural and comfortable visual experience.

Minimal to Zero Blue Light Emission

Blue light is a high-energy visible (HEV) light mainly from digital screens, LED lights, and the sun. It's a key factor in vision decline because it can penetrate the lens to the retina and cause retinal photochemical damage. Unlike LCD displays, which emit significant amounts of blue light, E Ink devices produce zero blue light when the front light is off. Even with front light enabled, E Ink's ComfortGaze™ technology ensures that the blue light emission is much lower than that of traditional digital screens. This allows users to read comfortably day and night without compromising their eye health.

Reduced Glare in Any Lighting Conditions 

E Ink displays are designed to be anti-glare with a matte finish, providing clear visibility whether you're indoors or out. They don't have to compete with the glare from the sun, making it much easier to read in bright sunshine. When you try to use a phone or tablet outdoors, you usually have to increase the brightness of the device to view the content, which can cause more strain over time. However, with an ePaper device, there's no need to seek shade—just enjoy your favorite books while tanning in the sun.

Benefits of Using E Ink Devices for Wellness

Enhanced Reading Comfort

E Ink devices deliver an enjoyable viewing experience that rivals physical books. The paper-like display eliminates the harsh glare and flicker of conventional screens, allowing you to read for extended periods without feeling tired. Whether diving into a novel or working through a lengthy research paper, you can keep your eyes refreshed.

Improved Long-Term Eye Health

Using E Ink devices can significantly protect your vision. By reducing blue light levels, ePaper minimizes retinal stress and lowers the risks of visual fatigue, myopia, or age-related macular degeneration. By choosing E Ink technology, you're not just improving your current reading comfort but also investing in the long-term health of your eyes.

Better Sleep Quality

Struggling to get a good night's sleep? The culprit might be your screen. Being exposed to heavy blue light near bedtime will suppress melatonin, which is the main hormone that regulates sleep-wake cycle. The loss of melatonin can lead to less deep, restorative sleep. Replacing your smartphone or tablet with an ePaper device can make a difference. With less blue light exposure, you can read or work into the evening without disrupting your circadian rhythm.

Less Addictive and More Focused

Most E Ink devices create a distraction-free space. Free from the constant bombardment of notifications and eye-catching animations, they promote intentional activities, ideal for deep thinking and focused work. Their minimalist interface and calming display discourage mindless scrolling, helping break the screen addiction, and thus boosting mental clarity for meaningful tasks.

Build Healthy Screen Habits in Daily Routine

Try these simple, science-backed strategies to keep your eyes healthy:

• Limit Screen Time: Be mindful of your screen time and set specific times to engage in offline activities to ease eye strain and fatigue.
• Follow the 20-20-20 Rule: Every 20 minutes of screen time, look at something else 20 feet away for at least 20 seconds to give your eye muscles a chance to relax.
• Use proper lighting: Make sure you have adequate light sources around you when using LCD or OLED devices, but avoid harsh or direct light that can cause glare.
• Keep screens at arm's length: Viewing screens too close can increase eye strain and the risk of nearsightedness. Try placing your digital screens 25 inches, or about an arm's length, away from your face.
• Switch to ePaper for various tasks: Replace traditional screens with E Ink devices for reading, note-taking, or working to limit exposure to backlight and blue light.
