How does blue light affect sleep?
Blue light has a big influence on our sleep-wake cycle. This is because the visible light spectrum also 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 lead to problems falling asleep and sleeping through the night. You can now prescribe high-quality blue light glasses for your customers to block that part of the blue light spectrum.


Do you need special computer lenses?
People are often unaware of how frequently they look at screens during the day. In reality, they are constantly surrounded by light sources such as digital devices and LED lights that emit a disproportionate amount of blue light. Blue light tends to scatter throughout the vitreous humor when entering the eye, causing so-called “visual noise”.
​
People may perceive this as uncomfortable glare and a reduction in contrast perception. Additionally, blue light causes longitudinal aberrations that may lead to blurred images. This unfocused “visual noise” can contribute to visual discomfort and symptoms associated with digital eye strain.
​
Common symptoms of digital eye strain (DES) are:
-
headaches
-
blurred vision
-
dry or burning eyes
​
Fortunately, these symptoms can be alleviated with little effort. Those affected can try to reduce their screen time, and they can also wear glasses with blue light blocking lenses.
