    • Abstract:
      The article focuses on advances made in the free-form technology, which is used in making single-vision atoric lenses. Free-form technology uses high-tech computer aided ray tracing technology to deliver the most advanced progressive-lens technology on the market. It allows the lens manufacturers to incorporate their specific design onto a lens blank without having to compromise visual acuity, as seen with traditional progressive lens designs. Free-form technology virtually eliminates unwanted radial astigmatic error, the most common cause of non-adaption in patients with presbyopia.
