This is interesting, my wife experienced something exactly the opposite. She started taking Vitamin D couple of years ago since she was quite deficient just like you. After a year or so of 5k IU daily, she started experiencing severe eye issues, including daily crust buildup, irritation, redness, and blepharitis.
We tried all sorts of drops and cleaning regimes to no avail. She went for another blood test and learned her Vitamin D levels were through the roof (somewhere around 90+). She immediately stopped the Vitamin D supplements and after a few weeks, all her eye issues were gone!
Goes to show we definitely need some good studies examining long-term Vitamin D intake.
