My sister-in-law called, worried about her husband. He was having headaches and neck and shoulder pain, and she didn’t know why. My optical instincts kicked in, and I asked when he had his last eye exam. It was about four years ago. He is 65, working from home on digital devices, and wearing the readers he got at his last exam. I told her his complaints were consistent with digital eye strain, that he needed an eye exam, and most likely progressive lenses. “But they’re so expensive!” she replied. I did my best to convince her that the investment was well worth it. It worked.
In my previous article, One Optician's Journey from State to State, I disclosed my intent to pursue the American Board of Opticianry's Advanced Certification (ABO-AC). I have a career bucket list and earning my ABO-AC was one of the top items. After speaking with respected fellow opticians about my personal goals and hopes for the evolution of the field, I casually mentioned that I wanted to earn my ABO-AC and then ABO Master designation someday. Repeatedly, I heard these five words, "What are you waiting for?"
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)
A little over a year ago, many of us including me began telecommuting as offices shut down. My pumps, blouses and blazers went into the closet. The pouch containing my cosmetics was zipped and tossed in a drawer. Offices are beginning to open again, and I hope I can remember how to put together an outfit that doesn’t include yoga pants, not to mention how to apply makeup. Prevent Blindness named April Women’s Eye Health and Safety Month, so it’s a good time to revisit those cosmetics, especially eye makeup.
There’s always an opportunity to improve someone’s daily life. I know many of my patients can relate when I mention my career and hobbies consume the bulk of my time. This usually leads to my curiosity about whether they are wearing the appropriate eyewear for both. I discovered how many ‘almost lost my vision’ stories came up. People suffer eye injuries from using improper eyewear or not using anything altogether. Scrapes and scratches on the cornea are extremely common (and painful by the way) but the good news is it is all preventable! Safety glasses over prescription glasses, protective goggles or face shields are protection for those precious eyes. There are a variety of safety glasses that can be worn over prescription glasses as well.
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.
