Course Description:

In this course, you will learn about patented break-through lens form and design technologies for better optimization of free-form progressive lenses. As ECP's our objective is to improve the progressive lens patient's visual experience. Even with free-form technology, progressive lenses continue to present challenges for some patients. Free-form was a technological leap forward, allowing for greater precision application of lens design and the optimization of the lens surface topography. In addition, it opened up the opportunity to compensate for individual 'as worn' frame fit parameters. The Rx design computation occurs in real-time and in unison with other parameters. Even high wrap sports frames can be compensated. So, free-form is great! But can it be made better? The answer is yes. You will learn in this course that the single vision blanks used in standard backside free-form progressive lens technology are not the ideal lens form foundation upon which to build a digital progressive lens design and why. You will learn about the optical fundamentals behind the unique Camber progressive lens blank and the unique patented Camber Steady Methodology technology that reduces not only unwanted cylinder to its mathematical limits but also reduces mean sphere power and its contribution to lateral defocus in a progressive lens.
