Mastering the Lensmeter 101 - Intro to Marco 101

Neil introduces this Masterclass series with a brief introduction of some of the topics he'll cover, as well as gives an introduction of himself.
Using a Marco 101 Lensmeter, Neil will cover topics from adjusting the eyepiece, spotting spherocylindrical lenses, common mistakes to avoid, transposing Rx's, and advanced prism techniques. Neil has an Advanced certification from the American Board of Opticianry and shares his more than 14 years of managing optical labs, from which he's taught dozens of students to confidently and accurately, master the art and science of the Lensmeter.

First time Marco user; I have one where the mires are off when the prism device is set at 0. They are @ .5d be and .5d bo (if it were a right eye.)
How do I adjust the mires back to zero?

[@UseMyFrame]

For a quick solution, try adjusting the PCD (Prism Compensation Device), located just behind the marking pins. As you turn the metal knob you'll see the target move inside the reticle. It will be tricky at first, but with a little patience you should be able to align your target back to perfect center. This is only a temporary solution, especially depending on how much it's off. If it's just a little bit it may have just been move accidentally; but if it's off by a lot then get it recalibrated because it will make spotting lenses with prism much more difficult.
Thanks for watching! :)

How do you change the bulb?

[@UseMyFrame]

The very front of the lensmeter flip open (the end opposite to the eyepiece), just pull the top down and the bulb will come out. Here's a link where we order replacement bulbs from called Hilco: www.hilcovision.com/f/LENS-METER-BULB-4007-110V-25W-FOR-MARCO-101
