More blue light exposure – independent of age.

The COVID-19 pandemic has drastically affected our work and personal lives, and 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.

What is digital eyestrain?

We are constantly surrounded by light sources like digital devices and LED lights that emit disproportionally high amounts of blue light.

Blue light tends to scatter throughout the vitreous humor when entering the eye, causing so-called “visual noise”. This could be perceived as discomfort glare and 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.

Headaches, blurred vision, dry or burning eyes are all common symptoms of digital eye strain (DES).

How do blue light glasses work?

A portion of light emitted by the sun falls in the blue spectrum, but 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 blue light spectrum that can potentially be harmful and irritating.

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

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

With ZEISS BlueGuard, 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.

Why is 400 nm the better standard of UV protection?
