Innovative Lens Technology Filters Blue and UV Light

Blu-Tech lenses filter harmful blue and UV light. 
LAKE MARY, Fla.—A Lake Mary-based company, eye solutions, is introducing Blu-Tech lenses, which use a patented Ocular Lens Pigment to filter blue and UV light that can harm the macula and contribute to Age-Related Macular Degeneration (AMD).

“We are exposed to more high-energy blue light both indoors and out than ever before,” said David Israel, chief operating officer of eye solutions. “Blu-Tech lenses provide the protection needed to guard the macula from oxidative stress and a lifetime of exposure from damaging blue light.”

According to Israel, Blu-Tech lenses maintain natural color vision and improve contrast sensitivity. He explained that the lenses filter out harmful blue light proportional to the damage that blue light causes the retina. Shorter blue light wavelengths are completely filtered out but as the blue wavelengths get longer and approach green they are filtered less.

Blu-Tech lenses are available in standard plastic in an indoor design. Israel said he expects to soon offer a proprietary high-impact material that meets the ANSI Z87.1-2003 safety standards in both the indoor and outdoor polarized lens designs.

Currently, Blu-Tech lenses are available exclusively through Signet Armorlite’s Signatek lab in Signet Armorlite’s backside digital lens designs.
