Saved My Life !
I am one of those persons who has an allergy to Nickel.  Unknown to me, my GLASSES FRAME contained Nickel, and was causing me endless discomfort (allergic skin reaction where the frames touched my temples and nose bridge).  After visiting more dermatologists than I care to remember (who were no help), I came across some internet articles on Nickel Allergies, ordered the product , found out my frames contained nickel, ordered some new FRAMES (that I first tested with the product to verify them nickel-free) and for the first time in years can feel comfortable wearing glasses !  Saved me endless suffering, and money too !
