Flickering Lights Health Risks and How to Avoid Them

Flickering Lights Health Risks and How to Avoid Them

One of the biggest advancements in lighting technology is LED light. The use of LED lighting has become extremely popular in our society. However, most of us are unaware of the fact that LED screens and light bulbs emit flickering light. The invisible flickering light emitted is harmful for us and can negatively impact our wellbeing and cause undesirable health symptoms.

In this article we explain what flickering light is and why it is harmful for your health. We will also guide you through our range of products that are specifically manufactured and designed to use special flickering free technology. That way you can feel reassured that you are using flickering free light bulbs and LED lights which do not compromise your health and overall wellbeing.

 

What is LED flickering light?

Flickering light means a constant fluctuation of light emitted which can be found all over society, including our home. LED screens like televisions and digital screens, as well as LED light bulbs emit harmful flickering light. There are two types of flickering light, visible and invisible.

Visible flickering light can be seen by the naked eye at a frequency range of 100 hertz. While any flickering light above 100 hertz cannot be detected by the naked eye. Therefore, you won’t even notice the harmful invisible flicker. Just because we cannot see it with our eyes, we shouldn’t underestimate it’s damaging effects. The invisible flickering light emitted from LED screens and light bulbs is actually the one we should be concerned about the most.

 

Is LED Flickering dangerous for your health?

Flickering light bulbs and LED flickering emitted from digital screens can cause numerous health problems and undesired health effects. Studies have shown that flickering light has detrimental effects and can invoke measurable physiological changes.

When exposed to flickering light, your eyes have to rapidly adjust to changing light output emitted. This strains the eye muscles and prolonged exposure can lead to the following symptoms:

  • Eye strain
  • Headaches
  • Blurred vision
  • Fatigue
  • Reduced visual task performance
  • Neurological problems

Exposure to flickering light has also been associated with triggers of epileptic seizures. Even though flicker is harmful for our health as reflected by studies, unfortunately there is not much awareness on this matter.

 

Should you be concerned about flickering lights?

Your eyes are exposed to artificial light all the time. Whether you’re at home, visiting the doctor’s office, shopping at the mall or supermarket, and working at your office, we’re all exposed to it! You can imagine the impact LED lights have on our eyes and overall health over prolonged exposure.

People who spend a long time at the office often report headaches, eye strain, fatigue and dizziness. These symptoms might be the result of prolonged exposure to flickering light from LED screens and lighting installed at your office. In certain industrial settings, LED flicker can also lead to performance issues and accidents at work.

Children are even more vulnerable and susceptible to these health hazards. In our developed technological society, they are exposed to LEDs in schools, homes, malls and everywhere else. Studying and reading for long hours under LED lights with high flicker can trigger eyesight problems in kids. The same applies for teenagers and young adults who spend a significant amount of time reading and preparing for their exams.

As you can see, flickering lights shouldn’t be taken lightly and further studies need to be done to continue learning about the undesirable effects on our health. To avoid developing symptoms and health risks associated with the emission of flickering light, we invite you to have a look at our wide selection of products which are completely flicker free.
