Q: Some knowledge of progressive lenses’ checking.

A: Progressive lenses can also be checked for mrp by measuring from the outer laser mark of one lens to the inner laser mark on the other lens, however that’s only completely true when both monocular pads are the same, when they are different the right total may come up correct, but each lens could be off somewhat. If you have a monocular pd that is the same in both eyes, you can start by measuring from the laser mark nearest to the bridge to the eye wire, and do that in both eyes. It should be the same, them you can go and measure from the outer laser marking to the inner laser marking on the other lens. This will not guarantee that you do not have prism, but will tell you if the lenses were laid out right. fact, all laser markings on all progressives that I know of are 34 mm apart
