In Part 1, we discussed Position of Wear measurements and how they affect compensated power. Now you’ll see why. Are all these measurements necessary? The answer is yes and no. To create compensated lenses, we must use values for one or more of the key POWs.
All over the United States, kids are returning to school. The beginning of school is also the beginning of sports seasons. With any sport, there can be injuries. Eye injuries during sports are common and can be devastating. There are over 40,000 sports related eye injuries each year in the United States. Thirty percent of them are among children under age 17. Ninety percent of these eye injuries are preventable.
Watching the reports about Hurricanes Harvey and Irma reminded me of “Tropical Storm” Sandy’s collision with Connecticut in 2012. My neighborhood was under evacuation order, but I had to go to work for a few hours to make sure that the offices in our ophthalmology practice rescheduled patients and had disaster plans in place. Then, I raced home.
In the beginning, corrective lenses were simple. They consisted of a spherical curve on the front and a spherical or toric curve on the back. If the front curve was a +6 and the back curve was a -5 the power of the lens was +1. Lens power was simple math, +6 + ( -5) = +1.
There’s a weird feeling in going back to your roots, especially years on down the road. Maybe it’s a drive past a childhood home, or stopping into the restaurant where you had your first job. The last time you were in this place, you were just starting out in the world. Now you’re a full-fledged adult, with all of the experience and wisdom and baldness that implies.
To make great eyewear, we need to identify the patients’ expectations. What do they need to see well, and what do they want to be able to do? If you don’t discuss wants and needs with them and you don’t tell them why you chose the products you did, and one of their friends tells them about a new product that they might have had interest in, the patient then assumes that either you didn’t know about it and you’re out of touch, or possibly that you didn’t care enough to discuss it with them. Then what happens? It prompts them to search for information on the internet and find volumes of half-truths online, which of course, they believe because you’ve lost credibility. None of these situations paints a very good picture of you as a professional who is on top of your game, does it?
