I have to admit, for a large chunk of my opticianry career, I did not devote enough attention to how ophthalmic eyeglass frames are designed, produced, their material make-up, or the company behind the product. My husband is an engineer by profession, and the way he would hold a frame and examine the hinges, the mechanics, the design, sparked an interest in me. To learn more, I took the CE Why You Should Know How Frames Are Made, where I discovered the complexity and artistry involved in making quality frames.
Winter is here, and even with shorter days, many consumers understand that sunglasses aren’t just for summer. But why do non-prescription sunglass wearers like to challenge eyecare professionals by asking if there really is a difference between expensive and inexpensive sunglasses? The question is almost always accompanied by that “gotcha” look. It seems as though they think that because they don’t need vision correction, they can spend as little as possible, and gain a bargain unavailable to prescription lens wearers. I’ve found, however, that precisely because they don’t wear glasses, emmetropes know very little about sun lenses.
I have been a high school teacher for 17 years. I started out as a science teacher and slowly transitioned to teaching a subject and skill I learned as a US Navy Hospital Corpsman over 20 years ago. I started a program teaching my students at East High School in Rochester, NY, an optician’s skills. Rochester has one of the highest rates of poverty in the nation. I knew that a program teaching students skills that made them employable. It would be a great way to help my students aim for a consistently growing profession. In the time I have been teaching I have also seen many children who had issues in class, both academically and behaviorally and I knew that a lack of glasses could cause some of these issues. In developing my program I knew that it wasn’t enough to simply teach students the skills, but that they had to use them and we could use their skills to make glasses for children in the Rochester City School District.
In Part 1 we learned that the individual designs of digital lenses take into account not just the prescription, but Position of Wear measurements, resulting in compensated power. In Part 2 we discussed which measurements are necessary, when to use default measurements, and lensometer power versus power to the wearer. Concluding the series, learn why your lab is your best resource for solving non-adapt issues.
It was Lord Kelvin, the great British physicist and thermometer enthusiast who said, “To measure is to know. If you cannot measure it, you cannot improve it.” Perhaps this is obvious, but it sounds more impressive when it’s said by a great scientist. (In the interest of full disclosure, he also said “Heavier than air flying machines are impossible,” which is obviously wrong. But having been forced to fly coast-to-coast in an economy-class middle seat, I don’t think he was that far off.)
