How Do Blue Light Blocking Glasses Help With Eye Strain?

If you spend a lot of time working on digital screens, you may notice that your eyes feel fatigued and uncomfortable afterwards. This is most likely due to a vision problem called digital eye strain.

Even though digital eye strain doesn’t typically have serious or long-term consequences, it can lead to unpleasant symptoms and affect your productivity levels. 

One of the most common causes of digital eye strain is the glare and blue light emitted from digital screens. Luckily, digital eye strain can be easily diagnosed by receiving an eye exam.

If your eye doctor diagnoses you with digital eye strain, they may recommend wearing blue light-blocking glasses. 

Keep reading to learn more about digital eye strain and how blue light-blocking glasses can lessen your symptoms. 

What is Digital Eye Strain?

Digital eye strain is a common vision problem that can cause a variety of symptoms. It is caused by prolonged digital device use, including computers, e-readers, and even smartphones.

Digital eye strain affects both children and adults and has increased in frequency over the past few decades. 

Symptoms of Digital Eye Strain 

Digital eye strain can cause a variety of symptoms. Most of these symptoms are temporary and tend to go away after your eyes get a break from your digital device. But sometimes, symptoms can continue for longer if: 

  • You spend several hours on your digital device without taking a break 
  • You view digital devices at a short distance 
  • You have underlying eye problems
  • You view digital devices in poor lighting 

Digital eye strain can cause the following symptoms: 

Additional Risk Factors 

You may be at greater risk for digital eye strain if you:

  • Spend several hours a day using a digital device
  • View digital devices too close to your eyes or at the wrong angle
  • Have bad posture while using your computer or digital device
  • Have underlying eye problems (even minor ones)
  • Don’t take enough screen breaks 

What is Blue Light?

Blue light is part of the visible light spectrum. It is the light we see that has the shortest wavelength and highest energy.

Sources of Blue Light

Blue light makes up approximately one-third of the light we see. Sources of blue light include:

  • Sunlight
  • Computer monitors
  • Smartphone screens
  • Flat-screen televisions
  • LED lights
  • Fluorescent light
  • Compact fluorescent light (CFL) bulbs
  • Tablet screens

Sunlight is the primary source of natural blue light, and digital devices emit only a fraction of that emitted by the sun. Even though digital devices give off a less intense source of blue light than the sun, we have much more exposure to digital devices and view it more directly than other sources. 

What are Blue Light Blocking Glasses?

Blue light glasses are glasses that block or filter out the blue light that comes from digital screens. Research shows that blue light glasses may:

  • Alleviate digital eye strain
  • Improve visual performance
  • Improve sleep quality

Blue Light & Digital Eye Strain 

Blue light can cause eye strain because blue light scatters more in the eye. This reduces the contrast we see and makes it more difficult for our eyes to focus when we view light at a lower wavelength. These factors can contribute to digital eye strain. 

How Do Blue Light Blocking Glasses Work?

Blue light glasses have lenses that are treated to filter out blue light. This treatment prevents glare and blocks the transmission of blue light, lessening the “scatter” that causes digital eye strain. 

Ultimately, blue light glasses can help your eyes feel more comfortable after spending time staring at a screen.

What Else Can I Do?

In addition to using blue light blocking glasses to alleviate digital eye strain, you can:

  • View your screen at an arm’s length from your eyes and 20 degrees below eye level
  • Set the brightness of your screen similar to the lighting in your environment
  • Follow the 20-20-20 rule
