Why do my eyes still get tired after reading on e-ink all night?

E-ink screens are marketed as "eye-friendly," but reading continuously all night can still cause eye strain and fatigue. The reason lies in incorrect usage.

Many people choose e-ink e-readers because they believe this technology protects their eyesight better than phones or tablets. (Image: Genk)

However, reading continuously throughout the night can still cause eye strain, dryness, and fatigue, just like reading paper books. (Image: Genk)

E-ink screens don't emit light directly; they display images through light reflection, making them more comfortable to look at under normal conditions. (Image: Genk)

However, the eyes still have to constantly adjust to close-range objects, causing fatigue to appear after a few hours. (Image: Genk)

When reading in a dark environment with a backlight, the eyes must constantly adapt between areas of light and darkness. (Image: Genk)

Prolonged pupil dilation and constriction puts strain on the eye muscles, leading to pain and dry eyes. (Image: Genk)

Besides lighting, small font size or inappropriate line spacing also requires the eyes to focus more.

In reality, e-ink only reduces irritation; it doesn't replace the habit of taking proper breaks to protect your eyes.
