Have you ever wondered why ASUS ZenFones have a "Reading Mode" or "Blue-light filter"? You find it eases the strain on your eyes while reading ebooks or using your phone in the dark, but did you know it's the culprit behind many of the things we face at night, as well as cause possible eye damage? Read on to find out how you can protect your eyes more.


Note: this article contains some eye care-related terms and may confuse some readers. To make things a bit easier to understand, I've added links you can click through when a confusing scientific term comes up.


How does blue light damage the eyes?

The cornea, situated at the front of the eye, is a transparent cover that protects your iris, pupil, and anterior chamber. Light passes through the cornea and pupil before the crystalline lens focuses it on the retina.
High-energy blue-violet light in the narrow 415nm (violet) to 455nm (blue) is particularly damaging to eyes, in particular the lens and retina. The blue band of the light spectrum yields more energy and can pass straight through your eye – resulting in myopia (near-sightedness) and macular degeneration.
Blue light from monitors may cause eye damage, strains, headaches, and sleep disorders. Children are more susceptible to eye damage because their crystalline lens is less effective in filtering out blue-light, adding to the risk of age-related macular degeneration.


Here's also stuff that the scientific communities' research came up with:
  • Blue light suppresses the production of melatonin, the hormone responsible for regulating wake and sleep cycles, leading to longer wake times, and sometimes insomnia.
  • It could also affect blood and temperature regulation, as well as your blood sugar levels.
  • It could also affect people's moods, depending on their personality, and is sometimes linked to depression.
  • It is also linked to retinal toxicity, leading to irreversible damage to the eyes' retina and cornea.
  • It may also be the cause of higher rates of cataracts and macular degeneration.


Splendid Blue-light Filter
ASUS researchers have been hard at work trying to determine the right amount of blue light reduction for various tasks, especially for us PC, laptops and smartphone users, as we often use our devices under dark lighting conditions, intensifying the effects of blue light on our eyes. And they came up with Reading Mode, now called Blue-light Filter, and added it to their existing Splendid display enhancement technology.

Blue-light filter features a slider bar with four levels of blue-light reduction.
  • The first level gives you approximately 20% reduction, ideal for normal web browsing, while, with minimal color shift, still giving you excellent color reproduction for lifelike visuals.
  • The second level gives you approximately 30% reduction, good for viewing photos and videos.
  • The third level gives you about 50% blue light reduction, imitating the ideal look of book paper. This mode is ideal for ebook reading and word processing.
  • The fourth level gives you about 70% reduced blue light, perfect for dim ambient light environments.


Do you find that ASUS Splendid's blue-light filter feature helps your eyes when using your smartphone, or you only found out about it now? Did this article convince you to take better care of your eyes? Sound off in the comments.
