Here's what happened to me. I had constant eye twitching in my right eye for about a year. I noticed something actually growing in my contact solution or so it seemed. If I did not clean the case for a few days I would see something whitish and goopy, slimy, in the solution only on the right side. I'd clean it out and fill with new solution and check a couple days later and the goop would be back.
I realized at this point my symptoms were pointing to fungal/yeast infection and started on cat's claw and tried an herbal detox and then started taking garlic regularly. The eye twitching completely stopped and has not returned. During this time my eyes were constantly blurry. They seemed to go in and out of focus. Now that is mostly better.
Unfortunately, what the cleansing left me with is a lot of vitreous floaters in both eyes. They weren't there before I started taking the herbs.
