What is digital lens technology?
Digital lens technology, often referred to as "free-form" or "high-definition" lens technology, is an advanced manufacturing process used to create spectacle lenses that are customized to the unique prescription and ocular measurements of the wearer. Unlike traditional lenses, which are ground using standard tools and mass-production molds, digital lenses are created using computer-controlled surfacing equipment. This allows the lens to be manufactured with extreme precision—often in increments of 0.01 diopters—to account for factors like the frame's wrap angle, tilt, and the vertex distance from the eye. This process significantly reduces distortions, particularly in the peripheral areas of the lens, providing the wearer with sharper, clearer vision and a wider field of view, particularly for those with complex prescriptions or progressive (multifocal) lenses.
