You might want to try the MSM eye drops..that is what we use.
And also keep up the coconut oil but this is premade and sterile using the drops..10 drops daily is the requirement.
Very afforable..10 dollars from natural eye care .com
Contains: oxygenated water,Saline,MSM, that is sulfur..in it's natural state.
You know it is the same thing as the MSM everyone is taking for the colon and joints..great stuff and parasites hate it!The saline will kill the parasites in the eyes and the MSM deters them and not sure if it kills them, although someone said it does..wish ICU was around to confirm this....
