Light is necessary for vision and physical health. High-energy visible light in the blue and violet end of the spectrum may contribute to the development of certain retinal diseases or even directly damage the retina. But there is compelling evidence that blue light plays an important role in the regulation of circadian rhythms and therefore may affect sleep patterns. ZEISS Platinum Blue coating is designed to reduce the harmful effects of blue-violet light while preserving the healthy effects of longer wavelength blue light.

What Is Blue-Violet Light?

Blue-Violet is a portion of the visible spectrum known as High Energy Visible Light (HEV). HEV is light with wavelengths between 390-500 nm.  Scientific evidence has indicated there are benefits to HEV exposure, but there are potential risks as well. This is known as the ‘Dualism’ of blue light. 

The potentially harmful wavelengths of light are often referred to as Blue-Violet light, as our eye detects these wavelengths as a blue-violet color. Blue-Violet Light has a wavelength between 390-440 nm and is potentially linked to retinal damage.

Positive Effects of Blue Light

  • Blue light between 470 and 480 nm influences melatonin secretion to regulate the internal “clock.” (Circadian Rhythm)
  • Blue light (provided during daylight) blocks production of melatonin which boosts our mood and alertness.

Negative Effects of Blue Light

Some research has indicated that Blue-Violet light may lead to damage and death to the retinal cells

  • Light energy absorption (“heating”) may damage the retinal cells.
  • Potential damages in the retina may cause toxic reactions.
  • Macular degeneration and vision loss can be a severe consequence.

Dualism of Blue Light

Due to positive and negative aspects, we call this relationship the Dualism of Blue Light.  Blue light can be potentially be both: harmful or beneficial. The band between 440 and 460 nm exhibits the greatest overlap between the beneficial and harmful effects of blue light and therefore is called the transition zone.

Our goal is to block blue light below 440 nm to reduce the potential risk of retinal damage (blue curve), and ensure transmission of blue light above 460 nm to avoid disruptions to important biological and physiological functions (yellow curve).


Technology: ZEISS Platinum Blue Light Protect

Developed for Patients who spend a lot of their time indoors, and are exposed to blue-violet light from artificial sources such as LEDs, TV or computer screens and mobile devices. With distinct properties to reduce overexposure to the potentially harmful wavelengths of HEV shorter than 440 nmwhile keeping the transmission level above 460 nm (regulation of the Circadian Rhythm)

ZEISS Blue-Violet Light Solutions  

2 different surfaces, 2 different reflex colors

  • Front surface reflects approximately 20% of high energy visible light, reducing overexposure. The bluish-violet appearance is the portion of the visible light spectrum that is not being transmitted to the eye.
  • The back surface is optimized to minimized reflections backwards to the eye. It shows a bluish residual reflection.

The blue-violet and the bluish rest reflex do fit quite nicely together and do not compromise cosmetic appearance

ZEISS Platinum Blue AR Properties:

Blue Light Protection 

Specially tuned Blue Blocking reflectance targets harmful Blue-Violet light and reduces the amount that reaches the wearer’s eyes. Reduces overall exposure to harmful Blue-Violet from digital devices and light sources

Ultra High Scratch Resistance

Lenses resist scratches that can occur from wiping the lenses during cleaning 50% better than High Scratch Resistant lenses.  Bayer scratch resistance always >10 (scratch resistance similar to glass)

Easy Cleaning

Easy Cleaning as experienced when the lenses are brand new through the initial feel of “slickness”  as a cloth rubs the lens surface and smudges disappear                                                                                                                   

Anti-Static

Decreases the buildup of static electricity by over 90% to dramatically reduce the dust and debris static electricity would normally attract to the lenses
