## Questions & Answers

**Q: is this safe for anti-glare coated glasses**
A: It should be fine. I’m an optometrist and have been using this on my glasses that have the AR coating. I’ve also been using this on the oculars of my slit lamp (microscope to examine eyes) and 78D condensing lens (magnifying lens to look inside the eyes). So far no problems and it’s been working great.

**Q: Do I dry my eye glasses after application?**
A: I’ve been rubbing in the solution with a lens cloth until it is clear/streak-free.

**Q: Does it work on gas mask?**
A: it should work on any glass prone to fogging

**Q: Does it work on Football helmet visor?**
A: Sorry  I have no idea. In theory it should work but never tried
