Blue light is everywhere - did you know the reason the sky is blue is because of blue-light?
However, blue wavelengths in our electronics and energy-efficient lighting can become ... disruptive. Here are 3 reasons why you need blue light blocking glasses. If you're really serious about getting blue light glasses, then this is definitely worth a read.
1) Reduce Headaches and Migraines
There are countless clinical studies that support the harmful effects that blue light can have for people who are prone to headaches or migraine attacks.
Researchers have suggested that there is a specific neural pathway from the eyes to the brain—separate from how vision is transmitted—that ultimately causes blue light wavelengths to worsen and aggravate headache & migraine pain.
It is exposure to blue light that leads to high discomfort, a greater perception of pain and throbbing and even enhanced spreading of headache/migraine pain across the brain. And that does not even take into account that this colour of light can increase other symptoms of migraine too, including: aura symptoms, photophobia and light sensitivity, dizziness/nausea, and more.
2) Improve Sleep Quality & Stop Insomnia
Blue light can be especially aggressive in triggering sleeplessness. It suppresses melatonin production (the hormone produced to tell our body to go to sleep), whilst simultaneously altering our circadian rhythm.
Exposure to blue light can mean it takes an extra 1.5 hours to get into a deep sleep (A deep sleep being when your body starts to recover for the next day) when exposed to blue light. So if you think you're getting 8 hours of sleep, you're only getting 6.5!
To put it bluntly: Blue light’s interference with your sleep can lead to shortened total sleep time and diminished sleep quality.
3) Reduce Eye Strain & Increase Productivity
Blue light from Mobile devices & Computer Screens can lead to eye fatigue and soreness—both of which are hallmark symptoms of computer vision syndrome and eye strain.
In addition, blue light from mobiles & computers has been shown to worsen symptoms of dry-eye, especially since blue light can travel to the back of the eye (the retina).
The problems associated with these eye disorders are compounded the more you are exposed to light sources that emit high amounts of blue wavelengths.
How do our specialised BLM blue light glasses work?
So, our blue-light blocking glasses have a special coating on the lens that block blue light (up to 40% of it in fact).
That means if you use BLM glasses when looking at a screen, they can help reduce exposure to blue light waves that can kickstart headaches & migraines, keep you awake at night and really dry out your eyes.
