A friend of mine gave me a newspaper article that indicated that Testosterone applied to the eyes helped the condition of the eyes about which the article was written ( not blephrospasm). I assume that meant they applied a testosterone cream to the eyelid or thereabouts. So I went to the health food store to see if there was such a thing and behold there were several brand choices!
I bought some and have used it on my lids and all around my eyes for several months now. I feel it has definitely helped my sun sensitivity and the severity of how dry my eyes get. I also seems to have less often bouts of the "blinks".
Therefore, I would suggest you give it a try. I asked my medical doctor about it and he said the only side affect I could possibly get would be some growth of facial hair. I have had one or two pop up now and then, that's all. If it does for you what it's done for me, you'll feel it was worth it.
Good luck! Edie Gray
