Wondering if you can you wear blue light glasses all day?
This is a very common question we get asked.
The long of the short of it is no, it is not bad to wear blue light glasses all day. It is actually a good thing to do.
Blue light blocking glasses, otherwise known as computer or digital glasses are designed to block out the artificial blue light from entering your eyes.
Artificial blue light is commonly thought of to be found in our digital devices like laptops, computers, smart phones and while this is very true, in a modern world where we are surrounded by skyscrapers and lights - artificial blue light is found everywhere!
Let's start with a common misperception. Not all blue light is bad for us. Blue light is what keeps us alert and functioning during the day and is critical for our overall energy and wellbeing. This is because blue light activates hormones dopamine, serotonin and cortisol which are needed for our wellbeing.
Sunlight is our majour source of natural blue light that we need to survive and function. After the industrial revolution, humans have been exposed to too much artificial blue light from tv, offices, smart phones and laptops. The increase in artificial blue light on our eyes is what is damaging to our health and well-being. Back in the olden days, people were not exposed to this artificial blue light as they used candles not light bulbs in their homes after dark. This allowed them to have better circadian rhythms which leads me to my next point.
After dark is when blue light starts messing with our circadian rhythm. As night falls, our brain receives messages that it is time to get sleepy and go to sleep - blue light messes with that.
Instead of telling our brain it is time for bed, the artificial blue light we are receiving has the opposite effect - it informs our brains to be awake like it is daytime. Think it kind of like drinking red bull.
As we live in a digital world with TVs, computers and phones necessary for us after dark, avoiding blue light for many of us is a necessary evil. If you can avoid these modern appliances after dark, good for you!
If not, we would highly recommend a pair of blue light blocking glasses for your health and wellbeing. At 380 to 435 nm, blue light is at its most dangerous to the eye.
