Prioritise Eye Comfort with Low Blue Light ASUS Lumina OLED Laptops

Mar 08, 2024

Using an OLED laptop is important because it significantly reduces blue light exposure to your eyes compared to traditional LCD screens. You’ll understand more about the benefits of OLED laptops, read an experiment on how much blue light ASUS Lumina OLED panels block out, and browse the latest OLED ASUS laptop models in this article. Read on for more information on this amazing technology!

Blue light exists in nature and is present in sunlight, helping us stay awake and regulating our biological clock. Blue light normally isn’t problematic for human eyes. However, overexposure can potentially cause issues.

Disrupted Sleep Cycles

Prolonged screen time before sleep can disrupt sleep cycles because the blue light emitted from your device tricks the brain into thinking that it’s still daytime. This suppresses the generation of melatonin, which is a sleep hormone. Prolonged screen time is almost inevitable in modern life, luckily there are options to reduce the amount of blue light you are in contact with.

ASUS Lumina OLED panels reduce blue light emissions by 70% compared to traditional LCD screens. OLED panels also have a higher brightness perception, which allows users to view content at lower nits* without sacrificing clarity and color vividness. The reduced number of nits indicates lower brightness levels and contributes to less blue light exposure to the eyes, which results in reduced visual discomfort.

Retina Damage

In general terms, the pixels on device screens produce three colors: red, green, and blue. You may ask why red and green light aren’t mentioned when speaking of exposure to light from a device screen. This is because the wavelengths of red and green light often fall between 500 – 600 nm, while the wavelength of blue light is much shorter, at around 400 – 500 nm. Blue light is most harmful at 415 – 455nm. In any case, shorter wavelengths indicate higher energy and higher energy can cause cone cell damage.

Cone cells are concentrated at the center of our retina and are photoreceptors that help us see colors. According to a study conducted by Gifu Pharmaceutical University in which mice cone cells were exposed to red, green, and blue light, blue light is proven to be more harmful to cone cells. Only 20% of the mice cone cells survived after a 24-hour exposure to blue light, which shows a dramatic difference compared to the survivability of approximately 100% of mice cone cells under red and green light exposure for the same time period.

Children Are Most Vulnerable

As we age, the reception to light also changes in our eyes. Aged lenses in the eyes absorb less visible light overall, which means younger lenses are more vulnerable to potential damage from blue light exposure. Research shows that approximately 60% of the received blue light passes through the lenses to the retina of a five-year-old child, while only 20% of the same blue light reaches the retina of a 60-year-old adult. Most children today are frequently viewing screens. Because ASUS Lumina OLED panels significantly reduce the amount of blue light, they can provide a significant benefit ― especially to younger users.

To demonstrate that up to 70% of blue light is reduced on ASUS Lumina OLED panels, compared to traditional LCD screens, ASUS conducted a Bandpass Filter experiment. For this experiment, a bandpass filter allowing only harmful blue light (436 nm) to pass through was placed over the camera lenses of an ASUS Zenfone. Then an ASUS Lumina OLED display and an LCD screen display were placed side by side and viewed together through the Zenfone camera lenses covered with a bandpass filter.

A dramatic difference was shown in the brightness of the two screens: the OLED panel was almost completely dark while the LCD display was very bright. This confirmed that a significant amount of blue light was passing through the bandpass filter from the LCD display, and much less blue light was emitting from the OLED panel.

As the leading global brand for OLED laptops, ASUS offers OLED solutions for users of all types including advanced and casual creators, professionals, students, and laptops for daily use. ASUS Lumina OLED laptops are certified by TÜV Rheinland and SGS for low blue light. They are also certified Flicker-Free by TÜV Rheinland for a more comfortable viewing experience.

ProArt Studiobook 16 OLED (H7604) is a great, powerful option for advanced creators who work with 3D modeling on software such as Blender or Cinema4D. ASUS Vivobook Pro 15 OLED (N6506) is a practical, reliable solution for casual and professional creators, at an affordable price. The highly innovative Zenbook DUO (2024) UX8406 features a groundbreaking design of two full 14-inch OLED panels, providing twice as much screen space and four usage modes – dual screen mode, laptop mode, desktop mode, and sharing mode. This model is ideal for multitaskers or users who need a lot of flexibility. For everyday users who need a solution for basic tasks, online meetings and entertainment, ASUS Vivobook S 16 OLED (S5606) or ASUS Vivobook S 14 OLED (S5406) are ready to enhance modern life.

All of these models are OLED laptops with low blue light, providing visual comfort and vibrant viewing experiences in both bright and dim environments. Click the button below to check out ASUS Lumina OLED laptop options!
