My suggestion is to get a copy of the vision requirements and give them to your regular ophthalmologist. He/She can tell you how close to the test minimums you are adn give you options.
I've worn glasses most of my life and like you am seeing some changes now that I've passed the half-century mark. My eye doctor knows the requirements for the AME exam. So, she keeps those details in me chart and we discuss options for both my "day to day" needs and my flying needs.
This way, there are no surprises when I go for my flight medical.
