Are Computer Glasses Worth It?

Over the last couple of years, you may have noticed an uptick in people talking about computer glasses, or eyeglasses that are designed to filter out blue light from computer screens, smartphones, and tablets.

Are they worth it?


Although computer glasses don’t help with eyestrain, they canmake it easier for you to fall asleep at night. In a 2009 study, participants who wore blue-light blocking lenses three hours before bedtime experienced better sleep quality than those who didn’t. A 2015 study found similar results.

Why do computer glasses help you sleep? Blue light can alter your circadian rhythms, making it difficult to get a good night’s rest. Doctors recommend avoiding electronics in the hours preceding bedtime. Because this isn’t always feasible, computer glasses may serve as an alternative.

Is blue light dangerous?

Thankfully, there’s no evidence that the blue light from your computer screen can harm your vision long-term. A study conducted in 2015 found no measurable UVA or UVB radiation from computer screens, two forms of radiation known to cause eye problems. Another, more recent study published in the journal Ophthalmology found that the worldwide increase in nearsightedness is notbecause of blue light as previously believed, but because of an increase in near work activities — including traditional books.

Unfortunately, looking at a computer for several hours is liable to lead to eyestrain.

Symptoms of eyestrain include:

  • Blurred vision
  • Headache
  • Sore, itchy, or burning eyes
  • Sore muscles in the neck, shoulders, or back
  • Increased light sensitivity

To avoid digital eyestrain, we recommend practicing the 20-20-20 rule. If you’re performing near work (i.e., reading, using the computer), take breaks every 20 minutes to look at an object that’s 20 feet away. Focus on it for 20 seconds before returning to your task.

Should I buy computer glasses?

If you’re trying to avoid insomnia, computer glasses can be a worthwhile investment. Make sure to practice the 20-20-20 exercise to avoid eyestrain!
