# You Might Be Blinking Too Hard: Discover the Shocking Truth Behind Flickering Lights Have you ever stopped to wonder why some lights flicker—even when they’re supposed to shine steadily? While occasional flickering may seem minor, it can reveal surprising truths about your environment, your health, and even your power supply. Most people brush off flickering lights as a harmless annoyance, but new research uncovers why you might be blinking—or not blinking—when you notice them. This article dives deep into the shocking science behind flickering lights and what your eyes are really trying to tell you. ## What Causes Light Flicker?

While humans can’t visually detect this full frequency, older lights often produce perceptible flickers that cause eye strain and fatigue.
