Adjusting to astigmatism

To set the scene, I have never worn glasses before, however I got my Class 1 last year and it was conditional on having corrective lenses so week ago I headed into the opticians to kit me out with some specs. The result being that my right eye is pretty much fine but my left eye is +0.75 sph, -2.0 cyl and 92.5 axis.

I was told I didn't need to wear them all the time since my right eye happily compensates and I see everything in focus normally but I would need them when I was flying and that it would be good to wear them when I was driving or doing things like working on the computer, concentrating in a lecture etc, which is also what the lady at my Class 1 initial said would be the case.

I've been trying to do that for the last week but I'm finding it quite difficult to adjust to the new glasses. It was quite bad for the first few days and it was almost making me feel sick, which was what the optician said would be the case since I was making quite a large jump from no glasses straight to 2 dioptres.

Since then I don't feel sick and I've been getting used to them a bit more (focusing is fine and much improved over not having glasses) but I'm still having a few problems. Most notably, if I look at something that is square like a piece of paper or a computer screen the horizontal edges appear to diverge. Also if I look at something that is rectangular like a door or even the wall of a room and then tilt my head to the left or right, the shape shifts like a parallelogram so | | becomes / / (thats an exaggeration..but just to show what I mean!). Not in a huge way so that I won't notice it that much if I doing stuff, but if I stop and look at something and tilt my head then it is noticable. Lastly, I find that my distance perception has been thrown a bit, again, not in a major way but certainly noticable if I look for it and has caught me out a few times when picking up a pen for instance.

The optician seemed to think that I would take me a least a few weeks to adjust to the new glasses. Is that the case? Is it likely to get to the stage after a few weeks that I won't notice any problems with horizontal lines whether I'm wearing glasses or not and my depth perception will be fine?

Was wondering what other peoples experiences were for going from not wearing glasses to adjusting to wearing them, particularly with astigmatism. Do you find it easy to flip between wearing them for flying and not on the ground?

Thanks for the help!
