Sorry to hear about your fall anno - do hope your poor head doesn't stay sore for too long.
I first tried varifocals more than 20 years ago and couldn't get on with them. Then I tried dual-sight contact lenses - one lens has reading sight, the other has distance sight. It sounds odd, but they did work (except when I was reading and drinking a cup of tea at the same time - every time I lifted the cup to my mouth I obscured the right eye which had the reading sight, very disorientating!)
However, I tried varifocals again a couple of years later, making sure to buy the best available, and they were fine. I've never had a problem with them since. I guess I've just become accustomed to the need to move my head more, rather than just my eyes, so that I'm looking through the right part of the lens all the time.
