Old lenses: Essilor Natural poly. 16 (yes, 16) seg.
OD: plano
OS +0.50 - 0.50 X 105

New lenses: Unity PLX 15 Fixed design @16mm seg
OD +0.25 sph
OS +0.50 -0.50 X 105

Exact same B measurement of 26mm as old frame, in general almost identical frame (he didn't want to change much).
Patient is coming in with old lenses for point of comparison, but I'd like to have some ideas before then. My theories are perhaps the new corridor is too short and the design is too soft? I'm thinking about just replicating his old design, but I'd really like to give him a bit of an update, especially since that's what he paid for. If my suspicions are right, perhaps someone can suggest something that incorporates some design features from this side of the year 2000 that might work for him?
