SHAMIR BLUE ZERO™
Shamir has developed a lens treatment providing protection from the potential harm of natural and artificial light sources present in our everyday lives, from TV and computer screens, smartphones, tablets, and more (FIG A).
ARTIFICIAL LIGHT SOURCES
Based on a unique polymer formula, Shamir Blue Zero™ High Index 1.67 and Shamir Blue Zero™ Trivex™ blocks up to 98% HEV blue light in the 415nm - 435nm range. Shamir Blue Zero™Polycarbonate blocks up to 50% HEV blue light in the 415nm - 435nm range.
The percentage of blue light blocked can vary due to Rx thickness of the lens and by index, however on average Blue Zero™ blocks up to 3x more harmful blue light than a standard clear lens.
WHY IT'S SO IMPORTANT
Risks of overexposure
Extensive exposure to blue light leads to tired, dry eyes, eye strain, insufficient visual contrast, and headaches. It increases risk of macular degeneration and retinal disease.
Children are particularly vulnerable since the lens of their eyes are more transparent, allowing in more blue light from TV screens and tablets.
KNOWN BLUE LIGHT EFFECTS
Hard Time Sleeping
Decreased melatonin causes a disruption of the sleep cycle
Fatigue
Exposure leads to tired, dry eyes, eye strain and headaches
REDUCING A CLEAR & PRESENT DANGER
Research on visual health shows an increase in the incidence of ophthalmic disease related to today’s greatly increased exposure to artificial light, which is known to not only increase the risk of ocular disease, but it is also related to general health problems.
It can cause increased production of lipofuscin (FIG B) (aging markers and free radicals), and is an effective suppressor of melatonin. Decreased melatonin causes disruption of the natural sleep cycle and has been related to greater risk of a number of other conditions from cardio-metabolic problems to impaired immune systems.
WHY IT'S YOUR BEST OPTION
Shamir Blue Zero™ is a nearly clear lens. Shamir Blue Zero™ lens clarity ensures comfortable vision in all light conditions, maintaining optimal visual acuity. By absorbing just the right amount of blue light, Blue Zero™ protects health without interfering with visual comfort. It also provides UV protection by effectively absorbing harmful UVA and UVB rays. Shamir Blue Zero™ is suitable for everyone, recommended for children as well as adults, and for wearers of prescription or plano lenses. Shamir’s Blue Zero™ means that everyone’s visual health is automatically cared for!
HEV BLUE LIGHT TRANSMITTANCE
The graph below shows the percentage of light being transmitted through various (standard) clear and Blue Zero™ materials, along the light spectrum.
Transmittance was measured witha Spectrometer, using finished Plano lenses (2mm center thickness).
Shamir Blue Zero™ is available in all Shamir lens designs
The percentage of blue light blocked can vary due to RX thickness of the lens and by material index. The percentage blocked is three times more at 424nm, this represents the midpoint of the harmful blue light range.
