What Is Blue Light and Why Should You Care?

Blue light is a type of light that comes from the sun and digital screens like computers and smartphones. While some blue light is natural and even helpful during the day, too much of it—especially at night—can be harmful. It can make your eyes feel tired and may even affect your sleep.

How Do Blue Light Glasses Work?

Blue light glasses have special lenses that block or filter out blue light. These lenses may have a slight tint or a nearly clear appearance. By wearing blue light blocking glasses, you can reduce eye strain during long hours of computer use.

What Are Photochromic Lenses?

Photochromic lenses, also known as transition lenses, are glasses lenses that darken when exposed to sunlight and become clear indoors. They help protect your eyes from harmful UV rays and glare by automatically adjusting to light conditions.

Can Photochromic Lenses Block Blue Light?

You might wonder if photochromic lenses can also block blue light. The answer is yes, to some extent. Some photochromic lenses are designed to filter out both UV rays and blue light, offering a combined benefit.

Should You Wear Photochromic Lenses for Computer Use?

While photochromic lenses are great outdoors, they may not be the best choice for indoor computer use. They typically don’t darken under artificial light or in front of a screen. So, if you spend a lot of time on the computer, computer glasses with blue light filters might be better.

What's the Difference Between Anti-Glare and Anti-Reflective Lenses?

Both anti-glare glasses and anti-reflective lenses help reduce reflections and glare. However, anti-reflective lenses go a step further by allowing more light to pass through, improving clarity. They can be added to both photochromic and blue light glasses.

Do Blue Light Blocking Glasses Help with Eye Strain?

Yes! Wearing blue light blocking glasses can reduce eye strain from staring at screens. They help filter out the harmful blue light that can make your eyes feel tired and sore.

Can You Get Lenses That Do It All?

Some eyewear combines features like blue light blocking, photochromic properties, and anti-reflective coatings. These multifunctional lenses aim to provide comprehensive eye protection in various settings.

How Do You Choose the Right Eyewear?

Choosing the right eyewear depends on your lifestyle:

  • For outdoor activities: Photochromic lenses might be best.

  • For heavy screen time: Blue light blocking glasses are recommended.

  • For both: Consider glasses that combine both features, though they may be more expensive.

Are Blue Cut Lenses Worth It?

Blue cut lenses specifically block blue light and can be very effective if you spend a lot of time with digital devices. They’re worth considering if eye strain is a concern.

What You Need to Remember

  • Blue light comes from screens and the sun; too much can harm your eyes.

  • Blue light blocking glasses filter out this light and reduce eye strain.

  • Photochromic lenses darken in sunlight to protect against UV rays but may not help indoors.

  • Anti-reflective lenses reduce glare and improve clarity.

  • Choose eyewear based on your daily activities and needs.

  • Combining features can offer comprehensive protection but may cost more.


Protecting your eyes is important for your overall health. Whether you choose photochromic glasses, blue light blocking glasses, or a combination, make sure it fits your lifestyle. Your eyes will thank you!
