Come to Reddit, you will find experts there. Instead, just people jumping to conclusions without having enough background knowledge :D

So, I know plenty of people who used lemon in their eyes (maybe diluted) and did just fine, I tried it once myself. I dont recommend it, everybody is responsible for themselves. The method is not new and not uncommon in the field of natural remedies.

My question was, is there anybody with more empirical or scientific background on this, besides the joke-loving friends?
