Thanks, I'll drop them an e-mail. Not paranoid about revealing my name since I think there's no point in hiding it.

Bear in mind I'm just an engineer (not a pilot, nor an optometrist) who happens to own an altogether too interesting pair of eyes, which despite all their faults still work remarkably well.
I would be very surprised if the CAAS medical references the orientation angle of astigmatism. It doesn't really tell you anything useful about the severity of visual impairment. They will almost certainly only be interested in the power in dioptres of the astigmatism. The angle is needed to specify the corrective lenses, but does not give an indication of the degree of visual impairment.
Valid point. Still, I'm clueless then what to make of it. Best talk to those that write these rules then.
