IOT Free-Form Insights Part 12

In Part 11, we learned about IOT’s foundational technology, Digital Ray-Path®. This technology minimizes oblique aberrations in customized free-form lenses. We learned that “The value of the merit function is given by a weighted sum of the optical aberrations of the lens system. To achieve the best lens performance optimization of the optical system means finding the values of the free parameters that make the value of the merit function minimal.” (Dr. Jose Alonso et al)

Everything in One Place

Not long after Carissa Dunphy started at the front desk in a busy optometric practice, her superiors told her, “You can do more.” She agreed to train as a tech, and “got hooked” on the field. Carissa is now an ABO certified optician and founder of Optician Now, a web resource for opticians and those seeking certification or licensure. Her goal is to have one central place to find all kinds of information relating to the optician profession.

IOT Free-Form Insights Part 11

When it comes to free-form personalized lenses, we hear “Trust the Computer,” which we do, because our proof is in the patient’s response; they love them. Still, we want a rudimentary understanding of how free-form technology works. In this article, we will pull back the curtain and learn about the process behind IOT’s Digital Ray-Path® foundational free-form personalization technology. The upcoming Part 12 will delve into how IOT Digital Ray-Path 2 builds on the classic theory of oblique power error minimization.
