The Truth About Blue Light: What's Really Harming Your Eyes

Blue light is a high-energy light wavelength that’s naturally emitted by many sources such as the sun and artificial sources like screens, LED lights, and digital devices.

Blue Light vs. The Sun

Blue light seems to be the buzzword in eye health these days. Everyone’s talking about how screen use are impacting our eyes—and while it’s true that prolonged screen time can cause strain, we often overlook the real heavyweight in blue light exposure, the sun.

Just 20 minutes in the summer sun exposes your eyes to as much blue light as spending more than 6 hours in front of a screen. 

Natural sunlight is the largest source of blue light, and when combined with harmful UV rays, it can lead to long-term damage, like cataracts and macular degeneration.

That’s why sun protection for your eyes isn’t just an option, it's a must, especially in the summer months here in Bundaberg!

Here’s how you can shield your eyes:

1. Wear quality sunglasses that block 100% UV rays. Look for lenses that are Category 2 or 3.

2. Use a hat for added protection. A wide brim can reduce UV exposure by up to 50%.

3. Seek shade during peak UV hours between 10 am and 4 pm.

   
   

While blue light glasses are great for reducing eye strain indoors, the bigger battle for your eyes happens outside. Protecting your eyes from the sun isn’t just about comfort—it’s about safeguarding your vision for years to come.

This summer, as you slap on the sunscreen, don’t forget your sunglasses too. Your eyes will thank you!
