Enhanced eye comfort is essential for prolonged digital device use. This feature ensures that eyewear lenses effectively filter a specific portion of the blue light spectrum, providing a benchmark for high-performance functionality.
The Science of Blue Light Filtration
In the eyewear industry, blue light blocking is the measure of a lens's ability to intercept light waves in the 380nm to 500nm range. Digital screens and LED lighting emit high levels of this blue light, which can contribute to eye fatigue and disrupt sleep cycles. For computer glasses, achieving a "50% block" means the lens is engineered—either through specialized pigments in the lens material or multi-layered surface coatings—to cut the transmission of these high-energy waves in half. This performance helps create a more balanced visual experience, reducing the "glare" felt during long hours of screen time without severely distorting natural color perception.
Validation through the High Performance Mark
By meeting our selected technical benchmarks, your eyewear products become eligible for the Intertek High Performance (HP) Mark’s Blocks 50% Blue Light. We apply a modified version of EN ISO 12312-1, determining the blue light transmittance within the range of 380 to 500nm.
This mark serves as a ‘proof of performance’ by validating that your product meets the High-Performance Mark standards. You can display the mark on product tags, brochures, packaging, websites, and in both online and offline stores across multiple channels, confidently signal to consumers that the performance claims of your products are verified.
