Why is blue light filtering important?
What is digital eye strain?
We are often unaware of how frequently we look at screens during the day.
In reality, we are constantly surrounded by light sources such as digital devices and LED lights that emit a significant amount of blue light.
We often perceive this as uncomfortable glare and a reduction in contrast perception and aberrations that may lead to blurring.
Common symptoms of digital eye strain (DES) are:
headaches
blurred vision
dry or burning eyes
Try to reduce their screen time, and try glasses with blue light filtering lenses to help reduce digital eye strain.
How does blue light effect sleep
Blue light has a big influence on our sleep-wake cycle.
Daylight contains blue light waves – and these help us stay awake and alert during the day.
As the sun sets, the lack of light signals the body to produce melatonin. This hormone is responsible for us getting tired and falling asleep.
Blue light from smartphones or laptops for example, can interfere with the release of melatonin. As a result, this can often leads to problems falling asleep and sleeping through the night.
Stop using digital devices at least two hours before you want to go to sleep, or consider using blue-light filtering lenses
