Blue light blocking lenses

Blue Light - BlueGuard

The material that can stop the annoying and harmful blue light

Blue light is a component of the visible light spectrum characterized by a wavelength between approximately 450 and 495 nanometers. It is naturally present in the solar radiation that reaches us, but is also emitted artificially by numerous commonly used light sources.

In fact, most modern electronic devices such as smartphones, tablets, computers and flat-screen televisions emit blue light due to the LED or LCD technology used for their displays. Likewise, the latest generation of LED lamps, increasingly widespread for home and public lighting, produce a significant amount of blue light.

Thus, while the sun remains the primary source of blue light exposure, the increasing use of digital devices and artificial LED lighting systems has greatly increased our daily contact with this particular portion of the visible spectrum.

Increasing the time spent in front of these devices affects visual comfort.

Zeiss BlueGuard® lenses are specially designed to filter out high-energy blue light, the portion of the blue light spectrum between approximately 415 and 455 nanometers. This wavelength range, if absorbed in excess, can potentially cause damage to the retina and contribute to eye strain.

Thanks to a special coating, BlueGuard® lenses effectively block this harmful component of blue light, minimizing eye exposure. At the same time, they allow the wavelengths of blue light between 465-500 nm to pass, which are crucial for maintaining normal circadian rhythms.

An additional advantage of these lenses is their ability to minimize annoying reflections and glare, especially when using digital devices or in the presence of strong light contrasts. This results in a clearer and more comfortable vision.

Here is our catalog of prescription glasses. Choose the frame that you like the most and when choosing ophthalmic lenses, opt for the anti-blue light technology.
