Eyesafe has introduced a new technology called Eyesafe RPF60 that they claim is the most powerful solution for filtering out blue light from screen accessories. It is designed to filter out blue light, especially in the 435-440 nanometer range. Unlike some competing solutions that reduce blue light but negatively impact the color and display quality, Eyesafe RPF60 claims to maintain vivid colors and display performance while providing blue light protection. The technology is built on unique materials and is covered by a patent portfolio.
There are standards for blue light safety. The standards require that screen accessories, such as screen protectors or other products used with electronic devices, have the capability to filter a significant portion of blue light in the range of 435-440 nm, the range considered critical because light in this range is more likely to penetrate the eye’s protective structures, like the cornea and lens, and reach the retina.
Organizations like TÜV Rheinland provide certification for products that meet these blue light filtration requirements. In this case, TÜV Rheinland offers a “xx% Blue Light Reduction certification.” For a product to receive this certification, it must filter at least a specified percentage of blue light within the 435-440 nm range while minimizing any negative impact on color and luminance.
Another aspect of these standards is the introduction of RPF, which stands for radiance protection factor. RPF is designed to be similar to SPF (sun protection factor) used in sunscreen products. In the context of screen accessories, a higher RPF value indicates better protection against blue light. For example, an RPF60 means that a screen protector filters 60% of blue light within the specified range. This metric allows consumers to make informed choices based on the level of protection they desire.
