Blue Light Awareness: Protecting Your Eyes in October

What Is Blue Light?

Blue light is high-energy visible (HEV) light with short wavelengths (around 400–490 nm). While natural sunlight is the main source, digital devices—phones, tablets, computers—emit significant blue light. With the average adult spending over 7 hours a day on screens (Statista, 2024), awareness of its effects is important.

The Impact of Blue Light on Eye Health

Prolonged blue light exposure can contribute to:

• Digital Eye Strain (DES): headaches, blurred vision, dry eyes. Over 60% of adults report DES symptoms (American Optometric Association).

• Sleep Disruption: blue light interferes with melatonin, affecting sleep quality.

• Potential Retinal Stress: research suggests chronic exposure may cause long-term retinal fatigue.

Myths vs. Facts

• ❌ Myth: Blue light permanently damages eyes.

• ✅ Fact: Evidence shows discomfort and strain but no permanent damage.

• ❌ Myth: Sunglasses indoors prevent blue light effects.

• ✅ Fact: Only lenses with HEV/blue light filtering coatings are effective.

How to Protect Yourself

1. Blue Light Glasses: Reduce glare, strain, and improve comfort.

2. 20-20-20 Rule: Every 20 minutes, look at something 20 feet away for 20 seconds.

3. Device Settings: Enable blue light filters or night mode.

4. Proper Lighting: Avoid dark rooms with bright screens.
