What Is Blue Light? | Symptoms & How Gleam Can Help
Blue light is a high-energy, short-wavelength light emitted by digital screens, LED lighting, and the sun. Extended exposure — especially from phones, laptops, and monitors — is linked to digital eye strain, disrupted sleep, and symptoms like headaches and blurred vision. Blue light blocking glasses, like Gleam's, filter a portion of this light to help reduce those effects during long screen sessions.
Computer Vision Syndrome (CVS) and Symptoms
Computer Vision Syndrome - also referred to as Digital Eye Strain - is a syndrome of our digital world. Its common symptoms include neck and shoulder pain, eye strain, headaches, dry eyes, insomnia, and blurred vision.
It's easy to dismiss these symptoms as everyday stress, going about your day without realizing you're experiencing Digital Eye Strain.
What causes it?
It's the 10 + hrs a day we spend working in front of a computer. Or the countless hours we spend texting, on social media, and doing research as part of daily life.
Overexposure to blue light and reduction in blinking are significant culprits. So the more we work hard, the more we strain our eyes.
Treatment & Prevention
In addition to scheduling a checkup with your optometrist, healthcare providers such as Cedars-Sinai suggest you do the following:
- Practice the 20|20|20 rule - every 20 minutes look at something 20 feet away for 20 seconds
- Remember to blink more often (easier said than done)
- After 2 hrs of screen time - take a 15-minute break
