Hi there. Nice graph.
As far as your vision is concerned, some people are able to make things a bit more comfortable by using cheap and cheerful ready readers, reading glasses from the supermarket or department store for a few pounds/dollars a time. Of course that's only an interim solution, but if it makes rerading easier for even a short while, it could be worth trying.
As you have alrerady identified, it is worthwhile waitng forr it to improved. Keep up the good work!
