can someone help me with the following please:

would this changeover be acceptable:
R: -4.00/-1.00x90
L: -4.00/-1.00x90

change over to replace a clients broken frame is 56-14
new frame is 56-12.
the shape of the new frame does not allow for any alteration of the decentration of the OCs. that is, they must be fitted on the new frame's GCD.

Thanks.
