We all understand the dangers of being exposed to the sun for too long but have you heard about the dangers of blue light?  As a VSP Ambassador, I was sent the below infographic and asked to share the dangers of blue light with you. I’ll admit that I wasn’t familiar with blue light until now.

The Dangers of Blue Light

The Dangers of Blue Light

So just what is blue light? Blue light is just what it sounds like—it’s blue and it’s light. But it’s a high-energy wavelength and actually penetrates all the way to the back of the eye. Over time this can cause damage. We’ve always been exposed to blue light from the sun—that’s why the sky is blue—but it would fade at night. Today it is radiated by everyday objects like fluorescent/CFL/LED light bulbs and the screens of computers, tablets, smartphones and televisions.

I mean, really think about it.  If you’re anything like me, you are exposed to blue light all the time from your computer screen, television, iPhone, the lights we use, etc.  I’m always exposed to some sort of blue light from the time I wake up and read my emails to the time I go to bed & check my iPhone for last minute messages. Even the kids are exposed to it with handheld game units, smartphones, iPads, etc.

With an increasing number of blue light sources in our daily lives; an aging baby boomer population; and a growing number of children learning on digital devices, preventing blue light exposure has become a priority to help reduce the risk of eye conditions like macular degeneration.

Thankfully, there is something that you can do to protect your eyes. UNITY lenses with blue light protection filter harmful, high-energy blue light but allow innocuous blue light to pass through. This allows for optimum protection without compromising color or depth perceptions. The lenses also block UVA and UVB radiation. The lens filters across the entire blue spectrum from 400-500nm with more protection commensurate with potential damage. Essentially, more protection toward 400nm because the most damage occurs at that end of the wavelength. The lenses also help filter the specific wavelengths that impact the sleep/wake cycle.

Sunglasses do not block blue light. However, UNITY lenses with outdoor blue light protection blocks harmful blue light as well as UVA/UVB radiation. The outdoor version looks like a typical sunglass. Who would need this lens?

  • Children under 18 because they don’t have the ocular lens pigments adults have
  • Post cataract patients
  • Patients who use computers or digital devices throughout the day
  • Patients at risk for AMD

  6. I get computer vision syndrome if I'm on my laptop for too long. If I'm on my desktop, it's ok. I wonder if that has anything to do with blue light. Yikes!
