@hazardwarning I had astigmatism. The opticians were also keeping track of my developing cataracts. In December 2016 I went in to get a new prescription only to be told there was little than new lenses could fix, such was the state of the cataracts.
The following year, between April & July, I had the cloudy lenses removed & corrective artificial ones inserted, which rectified the astigmatism issue. I now have 20:20 vision in one eye & life in general is way better.
I still use glasses but only for reading/computer work.
