20/20's Resource for Education

Education

A Dispenser’s Guide to Compensation –
Part 3

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.

Education

Taking the Measure of Digital Centration Systems

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.)

Education

What Color Are My Socks?

Every morning, before he left for work, my dad would ask my sister and me, “What color are my socks?” He was satisfied if we said they were brown. We thought he was either trying to get our brains primed for the school day, or he just hadn’t taken the time to check before he rushed out to catch the train. Like most kids in those days, we didn’t question our parents much.
