My eye doctor told me my blood sugar was destroying my retina years before I noticed anything. I looked into what actually happens at the capillary level and found a breakdown that explains it better than any appointment I've had.
I had been managing my numbers reasonably well for years. A1C mostly in the 7s, occasional dips to 6.5. I thought I was doing enough.
Then I had a dilated exam where my doctor mentioned early changes. not retinopathy yet, but the precursor signs. He explained it in about 90 seconds and sent me on my way
I went home and tried to find a clear explanation of what was actually happening in my eye and what I could do about it on a daily basis beyond the usual advice. Most of what I found was either too clinical or just repeated the same three things I already knew.
I eventually found a breakdown that actually explained the mechanism, what happens to the capillaries, why the retina is one of the first places high blood sugar shows up and what the daily habits are that actually affect this at a vascular level rather than just the general eat better message.
I can not paste the whole thing here but this covered it better than anything my doctor explained:

If you have been told to watch your eyes or have retinopathy in your family, worth reading before your next appointment.
