I tried one time, yesterday. My eyes are always red, itchy and tear up. So I experimented by putting 2 drops in my left eye only. Within 30 minutes, the pupil was dilated almost fully, the eyeball was visibly swollen and made the eye look larger. The redness was gone, but I looked like a freak. You can't convince me this is good for the eyes. Never again.
