The fact is, it can cause a few headaches, but the blue light from our smartphones, computer screens, and televisions is, on average, not a very good source of light. Even when it isn’t too bright, the amount of blue light in our environment is still a pretty high amount, which can cause our bodies to react in a way that doesn’t benefit us.
In a study published in the Journal of Science and Medicine, the researchers looked at 30 volunteers who were given a blue light source for 15 minutes. While there was no difference between people who were in the low- or high-light condition, the participants who were in the middle of the blue-light-intensity spectrum reported significantly more headaches and more difficulty concentrating.
This could be because the blue light is not very bright or because the blue light caused the headaches. The researchers speculated that blue light was the cause of some people having headaches because it is a wavelength that is easily absorbed by our eyes. It is also in the UV range, which is a wavelength that we can’t see through our eyes.
I think the more likely explanation for the findings is that people who are sensitive to light may have more difficulty with blue light.
The researchers suggested that blue light may be a contributing factor to headaches. Because light is the most important element in the body for the brain to work, if the blue light is not properly absorbed by the eye, the brain can’t function properly.

I’ve heard that some blue light may cause headaches, but I’ve never really been able to confirm that. I was curious to see if anyone else has found this to be the case and decided to take a look at a study done by the Canadian Neurological Institute and Hospital. The study involved some people who were sensitive to blue light (in this case, those who have sensitive to red light), compared to people who are not sensitive to blue light.
One of the main ways that blue light causes headaches is by interfering with brain waves. The study specifically looked at the brain waves of the people who were sensitive to blue light. The study found that people who were sensitive to blue light were much more likely to have a headache. This isn’t to say that a headache always causes people to be more sensitive to blue light. For instance, a migraine sufferer may be more sensitive to blue light than someone who doesn’t suffer from migraines.
The brain waves in the studies (and the ones conducted by the authors of the Blue Light Syndrome Study) were measured using a light sensor that measures the intensity of the light. Blue light was used because it’s the strongest light in the spectrum, so it would appear that if you were sensitive to blue light, then the light itself would be the culprit. The study found that people sensitive to blue light were much more likely to have a headache.
I’m not a doctor so I’m not sure what the authors of the study were thinking. They may have thought that because people who suffer from migraines are usually sensitive to blue light, it’s not that the blue light itself is causing the headache. It is one of the many factors that causes migraine headaches.
