The Effects of Blue Light

Until recently, blue light was something we didn’t know much about. Our Innovations Manager had growing concerns about the amount of time his kids were spending in front of digital screens. Television viewing, gaming, tablet and smart phone use and he wondered what the effects were. He soon found a lot of information on blue light along with many studies and research papers that link blue light exposure to a list of common ailments.

Symptoms of blue light over-exposure include:

  • Dry, irritated eyes
  • Digital eye strain
  • Difficulty falling asleep
  • Poor quality sleep
  • Disruption to the circadian rhythm (natural body clock)
  • Fatigue
  • Headaches


Eye strain

The flickering and glare of digital screens affects the contrast and sharpness of what we are viewing. This leaves our eyes straining to see clearly.

Less Consistent Flow

The less consistent flow of blue light makes it more difficult to focus.

Macular Degeneration

More and more studies and research papers are linking blue light exposure to long term macular degeneration, which can lead to blindness.

Artificial Light

Spending prolonged periods in artificially lit environments can also lead to blue light over-exposure.

Circadian Rhythm

Blue light disrupts our circadian rhythm, also known as our natural body clock. Our circadian rhythm affects our mood, memory, cognitive function and affects how alert we are. When our circadian rhythm is disrupted this affects our sleep patterns, making it more difficult to fall asleep and achieve a quality night sleep.

Good Blue Light

Blue light is emitted from the sun and a certain amount of natural blue light is good for us. However, over-exposure from prolonged periods using digital screens or spend in artificially lit environments negates the benefits of natural blue light consumption.

As technology has advanced so rapidly, blue light over-exposure is a new phenomenon. Fortunately, our Innovations Manager become so passionate about preventing the long-term damage blue light can cause, he has created an effective solution – Avatude Eyewear.
