Blue Light Filtration
Blue light is everywhere. It comes from the sun as well as from computer screens, like laptops, smartphones, tablets, or desktop monitors. It is the highest frequency of light on the visible light spectrum (it sits next to UV light). According to some studies and eye doctors, overexposure can lead to harmful results, like sleep disturbance, macular degeneration, and Digital Eye Strain.
Felix Gray lenses are specially designed to filter blue light. There are three ways to filter blue light. First, there is a yellow tinted blue blocking lens. While effective, this drastically changes our color perception. Plus, you end up looking like Bono. Second, there are coatings that can be applied on top of a lens. However, this is far from ideal. Coatings are generally ineffective, filtering around 25% of blue light and don’t fully target (arguably) the most important wavelength range of blue light (400-440 nm). Coatings also chip and wear away. Lastly, they deflect blue light so the lens appears blue when in front of a screen.
Felix Gray filters blue light differently. Our lens itself filters blue light and then we apply a premium anti-glare coating on top. This allows us to specifically target the important 400-440nm range and filter ~50% of blue light. At the same time, our lens appears clear instead of yellow tint or a blue deflection. We are the perfect balance between an effective blue light filter and a clear, normal looking lens.
By filtering blue light (and reducing glare), Felix Gray wearers overwhelmingly report less effects of Digital Eye Strain, particularly eye fatigue.
