Superior visual precision is essential for professional and everyday activities. This feature ensures that eyewear lenses minimize optical distortions and maximize contrast, providing a benchmark for high-performance functionality.
The Science of Optical Precision
In the eyewear industry, High-Definition (HD) performance is the measure of a lens's ability to produce a sharp, undistorted image across the entire surface of the lens. Standard lenses often suffer from "peripheral distortion," where the view becomes blurry or warped toward the edges. HD lenses are engineered using advanced Digital Surfacing or "Free-form" technology, which uses computer-controlled surfacing to map the lens with microscopic precision. This process accounts for how the eye moves behind the lens, ensuring that light is focused perfectly onto the retina regardless of where the wearer is looking. The result is a wider field of view, enhanced depth perception, and a "high-definition" experience that feels more natural to the human eye.
Validation through the High Performance Mark
By meeting selected technical benchmarks, your eyewear products become eligible for the Intertek High Performance (HP) Mark’s High-Definition Lenses. We use a combination of test clauses from EN ISO 12312-1, ISO 16321 and ANSI Z87.1 to assess several parameters related to image definition.
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.
