WHAT IS BLUE LIGHT
⚠️ Why It’s a Problem in the Modern World
1. 👁️ Eye Strain & Digital Fatigue
Blue light scatters more than other colors, so it’s harder for your eyes to focus.
That’s why, after long screen use, you feel:
Blurry vision
Headaches
Dry or tired eyes
Difficulty concentrating
This is known as Digital Eye Strain (DES) or Computer Vision Syndrome.
2. 🌙 Disrupted Sleep Patterns
Blue light suppresses melatonin, the hormone that signals your body it’s time to sleep.
So, using your phone or laptop before bed tricks your brain into thinking it’s still daytime 😴.
That’s why many people experience poor sleep quality, insomnia, or restless nights after screen time.
