prescribed prism with slab-off
We have a patient whos' doctor has prescribed combined prism in both eyes with a slab-off. Patient is currently wearing a progressive hi index lens.
Rx: od: +.75-.50x145 4bd 4bo
os: -4.00-1.50x180 3bu 4 bo
+2.75 add ou
Will a slab-off change prism in a progressive(in lft eye)????
Got nothing to do with the above job
Anyone notice how the above drawings appear to be 3-D and the black elipses seem to be circular drawing facing out. Differeing amount of face out effect in each.
