I'm short sighted about -7 or so and also have astigmatism. I went for an eye test recently and my eyes have changed a lot since my last test about 2 years ago. Also the axis on one eye has changed. The optician said this doesn't normally happen and is 'interesting' and asked me about my general health. This eye has also been twitching quite regularly for a couple of months now. Is this anything to worry about? BTW this is also my 'worst' eye.
I'm due to go back to my optician at the weekend but I am talking to them in my second language so sometimes I might miss something they say.
