I was able to eliminate eye floaters by taking eyebright and using Clark's Zapper also helped.
Eye flashes - Hulda Clark
wrote that mold toxins, especially aflatoxin, is similar in structure to LSD so gives some halucinogenic effects. I find that taking high doses of Vit C stops the flashes. Then identify the source(s) of molds, in the environment it could be in walls, showers, anyplace damp. I have found that many commercially prepared foods and supplements contain enough mold toxins to give me eye flashes and colorful displays. Detoxifying the liver may also help eliminate a buildup of these toxins.
Clark advises to peel all fruit and don't eat any fruit which has moldy places, soak nuts in 1/4 teaspoon vit c + water.
I have had eye pain from Toxoplasmosis (eggs carried in cat feces) and control the parasite
with hemeopathic drops. parasite
herbs do not penetrate the eye because of the poor circulation to that area.
