Hi hkg2008, I'm a Registered Optometrist (Part1) in HK and I just came across your post, but I suggest that you do 2 things. First, you need to have your prescription rechecked. It's unusual for astigmatism to increase by such an amount in adulthood. Second, you need to find an optometrist with a corneal topographer to rule out any corneal pathology associated with increased astigmatism. The earlier you find out what's going on, the better the long term management.
Hope this helps.
