losing your vision is one of the symptoms of type 2 diabetes
is it that you can't focus or is there kinda like 2 versions of the text smeared at some angle or so?
this is called double vision and it's caused by a fault in the aiming muscles that control the direction of the eye, they have to twitch very fast, about 200-300x per second and if there is something wrong with the signalling, latency, which i believe is caused by amylose from excess blood sugar - it will fail to home on the single position and potentially start to do orbital patterns or just generally wrong direction
i got this happening to me starting middle of last year and carbs in general were the main cause, what seemed to accelerate it was monster sugar free, which has sucralose and acesulfame-K in it
i discovered all this by accident when i switched to a milk diet to save money after my former sponsor for my work on indra rugged me at the last minute when he arrived in madeira
i have been able to slowly reverse this problem and i now am convinced that it also affects focus muscles and probably hardens the eye lens a bit as well as weakening the focus muscle so not only do you find it hard to read text you also find it hard to focus close
what really started off the questions for me was when i had a massive toothache triggered by potato chips with maltodextrin (alkali treated starch, which is extremely high GI) and i figured out that sugar was the cause of the nerve pain problem in my teeth, and then the stuff about the vision, and so on and so on
the cure is a low carb, keto/carnivore/paleo diet and when i say low carb, i mean, even tomatoes and cucumbers are a bit too sweet... skim milk is a bit too sweet...
i've just started eating exclusively for the last couple of days and i'm already getting way improved vision... when it gets bad, in the morning i can't read well for about an hour or two, and caffeine seems to help fix it somehow... but now i'm waking up almost clear vision again... and this was just from eating salads!
