Blue Light Vs. Screen Fatigue
"Blue light" and "screen fatigue" get used interchangeably, but they're not quite the same thing. Here's an honest look at the difference.
What Blue Light Actually Is
Blue light is a high-energy, short-wavelength part of the visible light spectrum, emitted by the sun and, in smaller amounts, by phone, computer, and TV screens.
What Screen Fatigue Actually Is
Screen fatigue, sometimes called digital eye strain, is a broader cluster of symptoms — dryness, blurred vision, headaches — caused mostly by reduced blink rate and prolonged close-focus, not blue light alone.
Why The Distinction Matters
Blue-light-filtering ingredients like Lutein and Zeaxanthin address one piece of the puzzle. Antioxidant support and healthy screen habits (breaks, blinking, distance) address the rest.
An Honest Nuance
No single ingredient eliminates screen fatigue entirely. VisioCore's formula is built to support multiple angles at once, but pairing it with regular screen breaks is still worthwhile.
