Free form, or digital, lens surfacing is an advanced, state-of-the-art surfacing technology. It utilizes highly complex computer algorithms to control a diamond tip lathe that carves the prescription into the back surface of the lens. To learn more about the benefits of free form lenses, check out our blog Free Form Lenses Aren’t Just for Progressive Lenses Anymore.
The surfacing treatment allows for precise lens designs tailored to all types of visual demands. There are no predetermined lens blocks or special tools for polishing. Free form lenses can be refined to 1/100 of a diopter or ten times more than a conventional lens.
Your single vision patients want one simple thing — to see better than ever without discomfort or ugly frames. As an eye-care practice owner, you want to meet those expectations. The problem with most single vision lenses is that the technology used to create them is severely outdated.
Why is it that Eye Care Practitioners (ECPs) commonly use finished and surfaced single vision lens technology almost 100 years old? It's time for eyeglass wearers and ECPS to begin benefitting from the superiority of lenses that fully utilize the tremendous computing power, lab processing capabilities, and base curve flexibility available in advanced free form single vision lenses.
HOYA realized the advantages of single vision free form lenses over non-free form, influencing the decision to leave conventional lens designs in the past and focus on digital, free form lens design.
Single vision free form lenses offer eyeglass consumers an improved degree of sharpness and field of view that surpasses conventional finished and traditionally surfaced lenses. Our highly-advanced free form SV designs deliver clear and comfortable vision.
