There are several blue light filtering solutions, but they’re not all created equal. Generally, clear blue light filtering lenses use a coating or what is known as a UV 400 or UV 420 lens. Both these lenses filter light particularly from 400-420nm. However, Felix Gray filters over 50% of the entire range and almost 90% of the most impactful wavelengths (380 - 440nm). Additionally, digital devices emit Blue Light in the most abundance at 455nm. Competitors filter ~2% at this nanometer, Felix Gray filters ~30%.
The reason we’re more effective is the way our proprietary lens filters Blue Light. We embed a naturally occurring blue light filtering ocular pigment into our lens. This makes it the perfect balance between a virtually clear and effective solution. It also has the added benefit of blocking UV rays as well! We also apply a premium AR coating, to block ~100% of glare. Blue Light and glare are two massive reasons for symptoms of Digital Eye Strain, like eye fatigue, headaches, dry eyes, and blurry vision.
We believe that Felix Gray lenses are the perfect balance between a virtually clear, beautiful lens and an effective Blue Light filtering solution. We did the research so you don’t have to! Check out our lens technology pages for additional information.
