The lens with built-in blue-violet light³⁰filtering and UV protection

What is blue light?

Sunlight consists of a spectrum of light at different wavelengths that divided into visible and invisible light.
Blue light includes wavelengths in the part of the visible spectrum from 380 to 500nm (ISO 20473). This is the highest energetic light reaching the retina (CIE 2023:2012).
The main and most powerful source of blue light is the sun, outdoor and indoors.

Depending on the wavelength, blue light can play a role in distinct physiological fields: retinal ageing, sleep.. to date, Shamir focused all its efforts on the spectral band from 400 to 455, internally referred to as blue-violet light.

Both UV and blue-violet light³⁰, have cumulative and irreversible impacts on the eyes.
Extensive research has been made on blue light-induced retinal ageing from the sun^3-29:
The spectral band from 400 to 455 nm (blue violet light³⁰) is one powerful modifiable factor promoting retinal oxidative stress and inhibiting antioxidant defence, thus accelerating eye aging ^{2 to 5}.
This has been recognized in ISO¹

Shamir Blue Zero™

Shamir Blue Zero™ is a lens material featuring a built-in filtering of blue-violet light³⁰ emitted mainly by the sun.
Based on a unique polymer formula, Shamir Blue Zero™ not only blocks harmful UV light from reaching the eye but also provides up to 3 times³⁴ more filtering of blue-violet light³⁰ than clear lenses³¹ while maintaining comfortable vision and ensuring high lens clarity³²

The powerful combination:
Shamir Blue Zero™ + Shamir Glacier Expression™

To deliver the highest optical quality solution, we integrated Shamir Blue Zero™ with the cutting-edge coating of Shamir Glacier Expression™.

Shamir Glacier Expression™ – The advanced premium coating
Shamir’s everyday premium anti-reflective lens coating provides powerful reflection reduction together with clear, sharp, and improved vision. It lets you look good, see sharp, and feel great.

LOOK BETTER Improved aesthetics with up to 70% less reflection³³.
SEE BETTER Visual clarity with +25% improvement in contrast sensitivity
~55% of eyeglass wearers gain significantly accelerated reaction times³³FEEL BETTER With Glacier Expression – more comfortable visual experience, day and night, helping reduce fatigue and eye strain ³³

Experience the powerful Advantages of Shamir Blue Zero™ + Shamir Glacier Expression™

Shamir Blue Zero™ + Shamir Glacier Expression™ – provide the eyeglass wearer with all the leading advantages of both the Blue Zero lens material and Shamir’s advanced coating:

More powerful filtering
When we combined these two products and compared them to clear lenses with the same coating, the results were amazing: up to 10 times³⁶ more filtering of blue-violet light³⁰ while maintaining contrast sensitivity and color perception.

More powerful uv protection
Full UV protection that blocks both incoming rays of UV light as well as those reflected off the rear lens surface, in all indexes.
