Is blue light damaging my eyes?

“I’m not much of a tech user therefore I don’t think I am at much risk of the negative effects of artificial blue light” a statement that, rather worryingly, resonates with too many people.  A concerning and detrimental belief that is actually leaving you more at risk to blue light than tech users themselves.




OK, so you don’t watch TV in the evening or play computer games or even scroll through your smartphone. Fantastic. So what do you do with your time? Maybe you go to the gym. Great, fitness is  a good way to look after your health.  But how do you track how far you have run on the treadmill? Through the digital display, which guess what? Emits blue light.


Or maybe you like to cook a nutritious healthy meal.  Brilliant. Abs are made in the kitchen after all. So how do you see to prepare your healthy meal? Your kitchen lights. And guess what? Artificial lights emit blue light. Maybe you prefer to get outdoors and be at one with nature, taking the dog for a walk around your neighborhood. Great idea. How do you see where you are going? Street lighting. And what does street lighting emit? Bingo, blue light.






You don’t have to be glued to a computer or TV to be absorbing harmful artificial blue light. It is around you everywhere, every day, everywhere you go. Even when you are doing your healthy activities like going to the gym or cooking a healthy evening meal, you are subjected to this over stimulating, sleep preventing, health affecting blue light.  


People who use technology for a living, working 8 hour shifts on laptops and computers often know and understand the impact of this on their health. It is these tech users that choose to address the negative effects of blue light through the likes of blue blocker glasses.  It is those that don’t use much technology that are ignorant to the sources of blue light that are the ones actually most at risk. It is these non tech users that go about their day, limiting their interaction with technological devices in favor of their health that are actually absorbing the most harmful blue light when compared to tech users using blue blocker glasses and other preventative measures.




In a nutshell, if you are able to see after dark without natural lighting in the form of candles, red lighting or fires you are exposed to artificial blue light. Whether you are a smartphone scroller or not, you are absorbing blue light. Your house lighting, the train, street lamps, illuminated street lighting, the light on your kettle, the light in your fridge, the gym, your favourite bar – blue light is literally everywhere.


Don’t be ignorant to the effects of artificial blue light that night after night is increasing your chance of diabetes and heart disease, prohibiting your weight loss efforts, contributing to your fatigue and poor concentration, leading to macular degeneration, making you feeling low or even depressed, causing insomnia and leaving you at greater risk of a stroke.


Blue light doesn’t just affect tech users – it affects us all.
