Once again I look forward to being humbled by those who can help me with this juicy piece of optics.
Recent rx from 2/2/20 Auto 2 fixed 18mm distance vision created diplopia but near was fine:
R -3.75 -1.00 x75
L -6.50 -1.00 x 110
add +2.50
Gun-shy about how well this would work (outside MD group wrote the script) I made a s/v distance only at cost from stock 1.67 decentered to achieve prism. He's worn them for a couple of weeks and it looks like all is well. However......
New rx to address diplopia:
R -4.25 -1.00 x50 1^ up
L -6.25 -1.25 x110 1^ down
add +2.50
Now we want to go back to the progressives but using Darryl's calculator I'm getting what will be 2.58^ prism UP in the LEFT at 15mm gaze drop. But he is wearing the current progressives for near comfortably. The old rx is creating 4^ up in the left.
So my question is will an Auto 3 11 or 13mm compensate? I'm inclined to think not. Slab off???
I've got to stop as once again my small room is filling with smoke...
