Introduction
Photochromic
lenses have always been about change, beginning with the first photochromic
lenses that were invented more than 40 years ago. Then, as now, the
primary motivation behind photochromic lenses was to create a lens that
was clear indoors and would darken automatically when the wearer went
outside.
Photochromic technology began with glass. Consumer fascination with the earliest glass photochromic lenses occurred just as CR-39� lenses had begun gaining momentum. However, it would take the industry another 30 years to develop a commercially viable plastic photochromic lens. Today, 10 years after the introduction of the first commercially viable plastic photochromic lenses, the various technologies that give lenses their photochromic characteristics continue to evolve. In 1999, the inventor of the original glass photochromic lens, Corning, introduced a new plastic photochromic mid-index lens material that can be processed thinner than standard index and is lighter weight than polycarbonate.
The latest developments in photochromic lenses have taken the products into a totally different arena - the world of lifestyle dispensing. This course takes a look at lifestyle dispensing with photochromic lenses. Wearers have always liked photochromic lenses for their comfort and convenience. Now with the improved performance of these lenses, doctors and dispensers are being given additional opportunities to meet a growing array of lifestyle needs. Understanding the available photochromic technologies and how to explain them to patients is key to providing eyewear that answers and enhances the lifestyle needs of your patients. Therefore, we'll begin this course by describing the two main photochromic technologies.
We'll also help you identify potential candidates for photochromic lenses. Contact lens wearers. People with light sensitivity. Teenagers. Emerging presbyopes. Outdoor enthusiasts and weekend athletes. People who spend the day going inside and outside. Patients who simply want a stylish, fashionable look. We'll explore them all. We'll take a look at dispensing these lenses too.
Finally, to make the process of dispensing photochromics successful and time efficient for everyone in your office, we'll show you how to use a lifestyle questionnaire that engages patients more fully in the discussion of their eyewear needs.
