What are the benefits of GLARE-X Optics?

Recently there are numerous reports and information coming to light about the effect of Blue Light sources on our eye health.  Excess blue light can cause numerous eye health issues, and for some people cause difficulty with getting quality sleep.  Many companies are offering glare blocking guards for tablets and computer screens, and optical companies are offering anti-glare coatings and lenses for prescription that also help filter out the excess blue light.  Here at Envision Eyewear we are offering our new GLARE-X Night Driving Optics collection (formerly known as our FOCUS Anti-Glare brand) which include many frame styles and lens options plus OTG Over-The-Glass frames to fit over your prescription eyewear.  See the charts below:

UV light begins at 400 nanometers and above (smaller wavelength number = faster wavelength and more dangerous).  Blue light is very intense and just inside our visible spectrum.  This chart shows how LED, CFL & Fluorescent sources deliver a heavy dose of blue light. Black Line = Human visible light spectrum. Purple Line = Typical LED lighting output spectrum. Blue Line = CFL and fluorescent typical output spectrum. Green Line = Incandescent typical output spectrum.

This chart illustrates how blue light rich LED light sources are nearly identical to our Circadian Rhythm sensitivity.  This means that excess blue light during the evening hours can make it difficult to fall asleep, and in some cases have a very negative affect on sleep cycles. Dotted Line = Circadian Sensitivity range. Black Line = LED typical output. Grey Line = Human visible light range.
