Quote - I just uploaded a small zip file to the dev site>expression morphs, with two eye open morphs, one for the left and one for the right. Still not perfect... Not exactly symmetric either, but can be adjusted a bit to get better symmetry.

Ockham has a script to mirror a morph, never used it myself, but I thought it may possibly help with your asymmetric eye open morphs. Quote from ockham's page:

"Morph Mirror. Creates a mirrored morph, either on opp. side of centerparts or on opp. limb."
