More blue light exposure – independent of age.

Research has shown that people of all ages are spending more time on digital devices. Besides facing potentially harmful blue light emitted by the sun, people also spend more time indoors where buildings are nowadays equipped with blue light-emitting LEDs. This can cause digital eyestrain and affect sleep.

What is digital eyestrain?

Do patients need special computer lenses?

Your patients 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”.

Patients 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.

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.

How do blue light blocking glasses work?

A portion of light emitted by the sun falls in the blue spectrum. Furthermore, almost all modern digital devices and LED bulbs also emit blue light. The human eye can’t block visible blue light, so over exposure can contribute to perceived eyestrain and blurred vision. Blue light blocking glasses can block that part of the blue light spectrum that can potentially be harmful and irritating for your patients.

With blue light blocking lenses from ZEISS, you can help improve your patients‘ overall quality of life.

 

ZEISS BlueGuard Lenses: The next generation of blue light blocking lenses

With previous products like the ZEISS BlueProtect coating, blue light blocking is achieved by applying a coating to blue light filtering lenses.

With ZEISS BlueGuard® Lenses, blue light blocking properties are now an intrinsic part of the chemical make-up of the lens material. In addition to blocking the potentially harmful blue light from the sun, it also filters irritating digital blue light that may affect your patients‘ eyes.
