Many people have cured many eye problems with urine therapy. I have cured my conjunctivitis by splashing urine on my eyes. I have tried this more than once successfully. Many people were able to cure cataract in their eyes and reduce the power of glasses in their eyes thus developing better vision.
If you drink urine it will detoxify your Liver. Recent studies show that there is a relationship between liver health and eyesight. Since drinking urine improves the liver health by removing toxins that also leads to better eyesight.
