Received my sprays today and was pretty excited to try them out. I am not one to have many aches and pains, however I was working at the computer today, and my right eye was throbbing a little. I thought hey I will just spray some on my eye. One is always a little anxious but my head did not shrivel up like a raisin, lol. And of coarse I closed it first dah. Incredible results...within seconds the throbbing was gone...what was really weird is in a couple of minutes the back of my head felt kinda funny like a bump....which is were your vision is located, then went away. So I came into the computer...and to my amazement everything on the screen is sharp and clear. I have always had good vision but recently have trouble focusing...if this is all it took...this is great.
