Can Sunglasses Block Blue Light? Here’s What You Need to Know

The question of whether sunglasses block blue light is a common one, especially with all the buzz around blue light filtering lenses. Let’s dive into the details to clear up the confusion!

Can sunglasses block blue light?

What Exactly is Blue Light?

Blue light is a high-energy wavelength found naturally in sunlight, but also emitted in large amounts by digital screens. Natural blue light helps regulate our sleep cycles and boost alertness, but overexposure from screen use can cause digital eye strain, headaches, and disrupted sleep patterns.

Do Sunglasses Block Blue Light?

Most standard sunglasses are designed to protect against ultraviolet (UV) rays but don’t filter blue light. UV rays are more immediately harmful to your eyes, causing long-term damage like cataracts and macular degeneration. Regular sunglasses excel at blocking UV light, but they typically do little to reduce the blue light coming from screens.


For sunglasses to block blue light, they would need specialized lenses designed for this purpose, which is not common in typical outdoor sunglasses.

What About Peepers Sunglasses?

Peepers offers a range of trendy and protective polarized sunglasses. It is important to note that these sunglasses do not provide blue light protection. Polarized lenses reduce glare from reflective surfaces like water or roads and block harmful UV rays, but they aren't designed to filter blue light​.


If you’re looking for blue light protection, Peepers has you covered with their Blue Light Focus™ Lenses, but these are specifically for indoor use when looking at screens. These lenses are available in many of their stylish reading glasses and help filter out high-energy blue light​.

Should You Worry About Blue Light Outdoors?

While blue light from the sun is naturally present, it's not as concentrated as the blue light emitted from your screens. If you’re primarily concerned about digital eye strain, focus on blue light filtering lenses for when you're indoors working on your computer or watching TV. When you’re outside, protecting your eyes from UV rays is the top priority. Peepers has you covered!

The Bottom Line: Stick to Sunglasses for Sun, Blue Light Glasses for Screens!

So, while your favorite shades will protect you from UV rays, they’re not your go-to for blue light protection. For screen-heavy days, grab Peepers’ stylish Blue Light Focus™ glasses, and when you’re out in the sun, their polarized sunglasses have you covered for UV defense. Each pair has its place, and now you can rock them both—indoors and out! 😎🌞
