What Is Blue Light and Where Does It Come From?

Blue light is a high-energy visible (HEV) light, naturally found in sunlight. But in today’s digital-first world, artificial blue light from screens is what most of us are exposed to for 8+ hours a day.

Common sources:

• Smartphones and tablets
  
• Laptop and desktop monitors
  
• LED and fluorescent lights
  
• TVs and digital billboards

How Blue Light Affects Your Eyes and Health

While moderate exposure to natural blue light is essential for alertness, too much artificial blue light can be harmful, especially after sunset. Here's how:

• Eye strain and fatigue
• Blurred vision and dry eyes
  
• Disrupted sleep cycles due to reduced melatonin
  
• Potential long-term retinal stress

How Blue Light Glasses Work: The Science Behind the Lens

Blue light glasses, also known as anti-blue light glasses or blue cut glasses, come with a special coating designed to block or filter harmful HEV light between 400 and 450 nm.

At Vishnu Opticals, our curated selection of blue cut lenses:

• Reflect artificial blue light from screens
  
• Reduce glare and harsh reflections
  
• Improve screen contrast and comfort
  

The result? Sharper, more comfortable vision for your everyday digital lifestyle.

What Experts Say:

Are Blue Light Glasses Worth It? What the Research Says

Some scientific studies show decent improvements in eye strain symptoms, while others call for more data. But one thing is clear: users overwhelmingly report relief and improved comfort when using quality blue cut lenses.

If you:

• Work on screens for extended hours
  
• Experience frequent eye fatigue
  
• Have trouble falling asleep after late-night screen time
  

...then blue light glasses are a smart, low-risk investment in your eye health.

• Spend 4+ hours daily on devices
