5 Health Issues Caused by Blue Light


If you’re reading this right now, you’re likely doing it from a computer, tablet, or cellphone. It’s almost impossible these days to not be glued to a screen. When I’m out and about and manage to rip my eyes away from my phone, I notice everyone is staring at their phones too. Contrary to popular belief it is not just young people who are glued to their screens; I sat in a cafe and watched at least 5 middle aged and elderly couples ignore each other as they scroll through their phones. My parents, who ridiculed me for my attachment to technological devices, are now either on their smartphones, or on their tablets. 

There’s nothing wrong with using our phones, tablets, and computers. They’re spectacular devices that allow us to connect to loved ones, and obtain information in a matter of seconds. The truth is though, our obsessive screen use is causing more damage than we would like to imagine. Here are five ways in which the dreaded blue light in our LED devices is monopolizing our health. 

Aging Our Eyes

The constant use of screens is actually causing our eyes to age almost 30 years! Optometrists are noticing that frequent screen users in their 30’s and 40’s have the eyesight of a 70 year old! 

Severe Migraine Headaches

The use of blue light, especially in the dark is often the cause of severe migraine headaches. More and more this is being seen predominantly in young people. 


The blue light is mainly known for destroying melatonin, the hormone we produce to help us sleep. We might think it’s okay to scroll through our phone at night, or fall asleep to the TV, but in actuality we are reducing our bodies natural hormone production to help us get a good night’s sleep. 

It’s Affecting Our Kids

Because our children are one of the biggest users of tablets and computers, often utilizing their devices just a few inches from their sleep, they have begun to suffer the consequences at an extremely early age. Kids have begun to experience chronic insomnia which is negatively affecting their school work. 

Increasing Chances of Cancer

Melatonin is not just a natural sleep aid, but an antioxidant as well. This antioxidant helps to prevent certain cancers and other diseases. Like I mentioned before, the main issue with the blue light is that it is reducing our melatonin production.

Ideally it would be best for our health if we could disconnect from these devices, but that’s just not the reality. We can, however, limit our usage or break it up into increments. There are also applications on phones and computers that allow you to actually “yellow” your computer so you are not staring at the blue light. Find a new bedtime routine of reading a book, rather than scrolling through your phone, or watching TV. Slowing our screen usage can help our health in the long run.
