i was searching for information about mineral deficiencies and this site finally gave me an answer:

> Iodine is another mineral that is important for maintaining healthy eyes. Iodine is necessary for the production of thyroid hormones, which play a crucial role in the development and functioning of the visual system. A deficiency in iodine during pregnancy and early childhood can lead to a condition called congenital hypothyroidism, which can result in permanent damage to the optic nerve and visual impairment.

> Calcium is not directly involved in vision, but it is essential for muscle function, including the muscles that control eye movements. A deficiency in calcium can lead to muscle weakness and spasms, which can affect the smooth movement of the eyes and cause vision problems, such as double vision or difficulty focusing.
so, i have been taking iodine for a few days now, along with boron, which reduces calcium elimination when intake is insufficient. i thought it was maybe potassium deficiency and that probably is a small part of it, in some other links i found to studies there was a small correlation with vision problems and hypokalemia. but the idea that this is related to calcium deficiency makes a lot of sense in light of the fact that tannic and gallic acids, found in coffee and red wine in substantial amounts, bind up calcium
which is funny because probably that period i was on a full time milk diet was probably helping somewhat, though weakened by my frequent intake of red wine and coffee.
so now i know what to look for, going to see if i can find a food grade dolomite on amazon and take it alongside the iodine and borax, and maybe it will incidentally improve my muscle strength, along with the potassium

i found this, should be pretty decent, i saw that zinc also has a role in eye health as well, and if my boron levels are low the boron will ensure i absorb it better
yeah, the problem is partly my close vision focus is weak, and my convergence at close distance is sometimes stubborn especially with horizontal objects, text being exactly this, so calcium helps convergence, and the potassium will improve overall muscle strength, i think there is also mineral deficiency effects with zinc in particular related to the visual cortex, so it's probably a combination of nerves and muscles combined
hopefully in a few weeks when i've got the whole stack under way i will start to see an effect because my vision at distance is perfect, these +1 prescription reading glasses only help at close range, beyond about 2m it starts to actually reduce my distance focus... which is probably also related to the calcium/potassium/zinc stuff
gonna be so releived if i can use the pc with text small after i am taking this stuff for a while... i always had perfect vision as a child but i used to have motion sickness too which has a connection with vision function, and i know that a high carb diet and probably the celiac reaction was at play with that, depleating nutrient absorption and causing inflammation
yes, i know some of it is age for sure, but i also know that i had all the symptoms of kidney damage in the last two years so i'm sure first of all it will take time for my kidneys to recover, and second, while they are still in a bad way i will need to supplement some critical minerals that it is eliminating due to being weak.
my close focus distance is about twice what it used to be, just before the double vision problem started. also part of what precipitated this was Monster sugar free drinks, which have sucralose and acesulfame-k and i'm pretty sure this caused kidney damage. it also made me very sensitive to maltodextrin, causing pain in my teeth, in the absence of actual other causes, that started about 10 years ago, also black pepper and stuff containing MSG would trigger it
i'm sure that all of it relates to calcium, magnesium, potassium and weak kidney function, and probably chronic dehydration
i'll be fine if my vision returns to the focal distance of before because that is still another foot away from my screen (used to be able to focus around 4 inches from my eyes, then maybe 10 more recently before this)
