Perfect for my swimming goggles

I swim laps every morning and this spray is a game changer. No more fogging up after the first two lengths. It lasts through several sessions before needing a reapply.

Good but needs frequent reapplication

It works well initially, but I find I need to spray it every day if I want maximum clarity. Maybe my expectations were too high regarding the 48-hour claim.

No more foggy masks

Since wearing glasses with a mask has been tricky, this spray solved the issue instantly. Easy to apply and doesn't leave any sticky residue.

Essential for motorcycle helmets

My helmet visor used to fog up in traffic jams. This spray keeps it crystal clear. The included microfiber cloth is also very soft and effective.

Great for winter cycling

Works well on my cycling glasses during cold rides. Keeps the view clear even when breathing heavily. Took off one star because the bottle is a bit small.

5 FAQ

Q: Is this product waterproof?

A: The anti-fog coating is water-resistant but not waterproof. Heavy rinsing or submersion may reduce its effectiveness, requiring reapplication.

Q: Can this be used on coated prescription lenses?

A: Yes, our formula is safe for most anti-reflective and UV coatings. However, we always recommend testing a small area first.

Q: Can I use this on my car windshield?

A: While technically possible, this product is optimized for personal eyewear and sports gear. For large automotive glass, we suggest our dedicated automotive line.

Q: Does it leave any smell on the lenses?

A: No, the formula is unscented and designed to be odorless once dried, making it suitable for sensitive users.

Q: How do I apply the spray correctly?

A: Clean your lens first, spray a small amount onto the surface, spread evenly with the included cloth, and let it air dry for 30 seconds before buffing lightly.
