All I have to say is this product is a COMPLETE waste of money. I purchased it for my swimming goggles and didn't work. Hopefully, I will find something that will work. Save your money. Try something else.
That being said, I must say that Bausch & Lomb's offers exceptional customer service. I called them and complain about this product and they sent me a refund. The product quality is poor, but their customer service is exceptional.
