If you spend all day on your phone or computer, you’ve probably heard of blue light. Blue light is essentially electromagnetic energy that travels in short, powerful waves. Electronic devices emit this energy during use, leaving you exposed to blue light every time you check your email or send a text message.
The Risks of Blue Light Exposure
Given just how much blue light most people are exposed to each day, it’s important to be aware of the potential health risks it can cause.
Here are some of the most common side effects of blue light that you may be at risk for.
Macular Degeneration
Macular degeneration occurs when the macula (a structure at the back of your eye) becomes damaged. This condition causes your central field of vision to deteriorate, leaving you to rely only on peripheral sight.
While age is the leading cause of macular degeneration, lab studies have raised the question about any link between the condition and blue light exposure. Scientists are still looking for the answer, but until then it’s best to assume that exposing your eyes to harsh electromagnetic energy for hours each day could speed up the structure’s deterioration.
Poor Sleep
A widely proven effect of blue light exposure is the loss of quality sleep each night.
During the day, light sensors in your eyes can detect the difference between harsh blue light and the natural, reddish rays of the sun, unfortunately, this distinction becomes weaker at night.
When the sun goes down, your body naturally begins to produce melatonin, a hormone that induces sleep. When you’re exposed to blue light in the evening, you release less melatonin which can delay or disrupt your sleep cycle.
While poor sleep can lead to fatigue and lack of energy during the day, it also puts you at risk for a number of other health concerns, including:
- Hormone-related cancers, such as prostate or breast
- Metabolic changes, particularly in your blood sugar
- Lower levels of leptin—a chemical that tells your body when you’re full—which can lead to overeating and weight gain
Eyestrain
Continuous use of digital devices causes you to blink less, which can dry out your eyes. Over time, this can lead to eyestrain that affects you throughout your waking hours.
While this condition feels different to each person, some common symptoms include:
- Dry or sore eyes
- Heavy or “tired” eyes
- Headaches
- Fatigued facial muscles due to squinting
Limit Blue Light Exposure
Luckily, there are some steps you can take to limit your exposure to blue light. Some easy methods include:
- Regularly applying eyedrops
- Setting your screens to “night mode”
- Use eyeglasses with the right prescription to avoid squinting
- Look away from your screen at least every twenty minutes
