Hi White Shark,
I see the rationale behind Dr. Christopher's eyebright formula eyedrops. For example, native American Indians used a red raspberry leaf eyewash for cataracts, and fennel seed is a de-calcifying agent which is a good idea to reverse the hardness of the cataractous lens. Goldenseal is antibacterial and cayenne pepper would improve circulation. But, this formula would probably sting like crazy which could cause conjunctivitis, and possibly corneal damage. I think any anticataract eyedrop, or any eyedrop, should not sting nor do any damage.
