Any ideas on this one please?

Patient has same frame, same prog (Solamax), OCs and heights same but is not happy. Rx was R-4.00 L-3.75/-0.25 x 5 add 2.25, Rx now R-3.50/-0.50 x 110 L-3.25/-0.25 x 95 add 2.25.

Says:
Eyes smart as soon puts on.
After a couple of days gets a low-level headache.
Momentary difficulty focussing.
Field of vision more restricted.

You can tell he's picky!

Less minus explains more restricted field, but I'm at a loss re the rest. No significant phoria. Presume front curve is the same, haven't checked but doesn't seem to relate to symptoms anyway.

Any help would be good!
