The Hannspree Lumo is a new entry in the growing e-reader market that promises to protect users’ vision while delivering a high-quality display. The tablet combines e-ink technology with a proprietary lighting system called ecoVision, and it is marketed as a healthier alternative to LCD and OLED devices.
Product Overview
The Lumo is an Android-powered tablet that can run common streaming apps such as YouTube, Hulu, and Prime Video. Its 7.8-inch screen is described as paper-like and can display 16.7 million colors. The device is 6.6 mm thin and weighs only 250 g, making it easy to hold with one hand.
Technology and Design
- EcoVision: Uses ambient light to illuminate the screen, providing a sharper and more vivid display when there is sufficient surrounding light.
- Front LED: Activates in low-light environments and automatically adjusts brightness based on ambient light levels.
- Flicker-free, anti-glare, blue-light-free: The display is designed to reduce eye strain and is marketed as safe for people with photophobia, migraines, and computer vision syndrome.
Hannspree claims that the lack of a traditional backlight reduces power consumption and eye fatigue. The tablet’s reflective display is said to emit less blue light than conventional screens.
Expert Opinion
Jay Neitz, an ophthalmologist and researcher at the University of Washington School of Medicine, told News Of Los Angeles that there are no significant advantages to reflective displays such as the Lumo’s.
“There is no good evidence that the blue light emitted by phones, tablets, or monitors causes retinal injury or increases the risk of macular degeneration,” Neitz said. “Many blue-light-blocking devices are marketed as protecting eye health, but controlled studies show little to no benefit for eye strain, visual acuity, or long-term ocular health.”
Martin Kent, Hannspree territory manager, counters that the Lumo is more than an e-reader. “By combining visual wellness, color, speed and flexibility, Lumo represents a fundamental shift in how tablets can and should work,” Kent said. “The tablet has greater consideration for our health.”

- While the device boasts a high-color, fast-refresh e-ink display, experts question the claimed eye-health benefits.
- The tablet’s specifications-7.8-inch screen, 16.7 million colors, 60 Hz, 5 ms, 250 g-make it a lightweight, portable option for users who value a paper-like feel.
- The e-reader market is expanding rapidly, but the Lumo’s lack of a confirmed U.S. release may limit its immediate impact.
The Lumo represents an intriguing blend of visual wellness and conventional tablet functionality, but its health claims remain unsubstantiated by current research.
