💻 What Is Blue Light?

Blue light is a high-energy visible light emitted by digital screens — phones, computers, tablets, and even LED lighting. While blue light is naturally present in sunlight, our constant exposure to digital sources has raised questions about how it affects our vision and sleep.

👀 How Blue Light Affects Your Eyes

Too much screen time can lead to symptoms known as digital eye strain, including:

• Tired or dry eyes
• Headaches
• Blurred vision
• Difficulty focusing

Although there’s no evidence that blue light damages the eyes permanently, it can contribute to eye fatigue and may disrupt your body’s natural sleep cycle by affecting melatonin production — especially when using screens late at night.

🕶️ What Blue Light Glasses Actually Do

Blue light–filtering glasses contain a special coating designed to block or absorb some of the high-energy wavelengths emitted by screens.
Many people report that wearing them:

• Reduces glare and visual discomfort
• Helps prevent eye strain during long work or study sessions
• Makes it easier to fall asleep after evening screen use

Scientific studies show mixed results — blue light glasses don’t prevent long-term eye disease, but they can help reduce eye strain and improve comfort for heavy screen users.

💡 Other Ways to Reduce Digital Eye Strain

Even with blue light protection, healthy screen habits are key:

• Follow the 20-20-20 rule — every 20 minutes, look 20 feet away for 20 seconds
• Blink often to keep your eyes moist
• Adjust screen brightness and contrast to comfortable levels
• Use artificial tears if your eyes feel dry

Combining these habits with blue light–filtering lenses gives the best results.

😎 Should You Get Blue Light Glasses?

If you spend several hours a day on computers or phones — for work, school, or gaming — blue light glasses can be worth it.
They’re also available in prescription and non-prescription options, so anyone can benefit from them.
