It's probably the lack of certain nutrients and vitamins getting to the eyes, but what does mainstream science actually say cataracts are?
They say:
Causes:
-Long-term exposure to ultraviolet light.
-exposure to ionizing radiation.
-diseases such as diabetes.
-hypertension and advanced age.
-trauma usually a result of denaturation of lens protein.
...just for some food for thought!
Usually, whenever we're told (by those that know better, you know, lol) something, the opposite quite often holds true.
Therefore,
Longterm exposure to ultraviolet light, prevents cataracts;
exposure to ionizing radiation, prevents cataracts;
sunlight Prevents diseases such as diabetes;
sunlight prevents such things as hypertention and aging;
You just have to look at what is said, and take the truth from it and re-insert the proper words back in that the illuminati forced the scientist, doctors, and researchers to remove.
You need only trust yourself, and test things out for yourself to know what is true.
