 What Is a Blue Light Filter? And the Best App You Should Be Using

In today's world, we stare at screens all day — phones, laptops, tablets — you name it. But did you know that the blue light from your screen could be messing with your eyes and sleep?

Let’s talk about what blue light is, why it matters, and which app we recommend to protect your eyes.

 What Is Blue Light?

Blue light is a high-energy light that comes from digital screens. It’s part of what makes your screen look bright and clear — but too much of it, especially at night, can cause:

 Eye strain and dryness

 Trouble sleeping

 Headaches or brain fatigue

Your brain thinks it’s still daytime when you stare at your phone late at night. That’s why it’s harder to fall asleep after scrolling in bed.

 How a Blue Light Filter Helps

A blue light filter reduces the amount of harsh blue light your screen gives off. It usually adds a warm, amber-like tone to your screen that’s much easier on your eyes — especially in the dark.

You can still use your phone, but it’ll feel softer, calmer, and way less tiring.
