Yeah, it's not a gradual thing at all. 2 weeks ago everything was just fine. Then I started seeing small floaters. I had been to the optometrist & he said I'll "eventually" have to have surgery to repair the leaky blood vessel(s). Then, right when everything came in for these two builds, I'm completely blind in my left eye.
Had the same thing happen 2 years ago with my right eye. First, detached retina, then a cataract a year later. My near-field vision's still not right on it so, like you said, magnifying glass for anything intricate (like connecting the front panel header).
It's funny that I finally got my blood sugar pretty well controlled after some 35 years of diabetes and now
my body falls apart.
No truer words were ever spoken than, "You are where you are in life as a direct result of your past choices."
