Product Spotlight – Sunsensors New Photochromic Lens Technology
Product Spotlight – SunSensors New Photochromic Lens Technology - Expanding Material –Casting –Coating Options Mark Mattison-Shupnick, ABOM, Deborah Kotob, ABOM Ophthalmic Level 2 Course Description Manufacturers are always searching for ways to improve the patient visual experience. This means pushing the limits of technology to discover new and better chemistry to produce the best material solutions for lenses including photochromic lens technology. Each photochromic technological advancement is born from either a material or coating solution improvement. This course describes the latest improvement for photochromic casting technology for in-mass and informs us of the new patented CrystalChrome, the newest thermal cured hard coat coating photochromic technology. This course is intended to help you better understand the MR series of SunSensors lenses with In- mass technology and it will also introduce you to CrystalChrome photochromic technology. Better technology means better products and satisfied customer. It is a Win, Win for the patient and the practice! Objectives 1. Learn a short overview of photochromic lens improvements. 2. Understand in-mass photochromic lens chemistry and how the distribution of dye molecules throughout the lens monomer 3. Learn the essentials for communicating the complementary patient benefits of high index, photochromic and new lens designs have on the patient satisfaction. WHY PHOTOCHROMICS? If money were no object, patients would want every lens enhancement and only the best materials used in the making of their eyewear. Todays informed consumer weighs the value of the lens options. Therefore, each benefits must be made clear to the customer hence each benefit must be clear to the optician. It is imperative that you know the details of ‘how and why’ new photochromic will improve optical performance convenience and make the life of the consumer better.
