Presbyopia is a condition that affects many as the lens ages, and is a secondary effect of cataract surgery. Multifocal lenses for the treatment of presbyopia have been undergoing cycles of development and improvement over the past two decades. The latest advancements have yielded lenses with a continuous range of optical powers, otherwise known as continuous transitional focus (CTF) lenses. Modern CTF lenses provide a more natural experience for patients while minimizing unwanted optical side effects.

老花眼是一种随着晶状体老化影响众多人的病症，也是白内障手术的一种继发效应。在过去二十年里，用于治疗老花眼的多焦点镜片一直在经历研发和改进的循环。最新进展已产生具有连续光学焦度范围的镜片，也就是所谓的连续过渡焦点（CTF）镜片。现代CTF镜片为患者提供了更自然的体验，同时将不必要的光学副作用降至最低。
