Compact and effective

Love the pen design. It fits right in my gym bag or pocket. One swipe is enough to cover both lenses of my safety glasses at work. Highly recommend for industrial use.

Great for winter driving

I use this on my motorcycle helmet visor during cold mornings. It significantly reduces fog buildup. I deducted one star only because the effect lasts about 4 days for me, not a full week, but still very good value.

Good but needs reapplication

It works well initially, but I found I needed to reapply it every few days if I wanted maximum clarity. It's not bad, just manage your expectations regarding the 'long-lasting' claim depending on humidity levels.

No more wiping my glasses

As someone who wears prescription glasses and a mask daily, this has been a lifesaver. No more constant wiping or blurry vision. The water-repellent feature is a nice bonus when it rains.

Perfect for my swimming goggles

This pen works exactly as described. I applied it to my swim goggles before a morning session, and there was zero fogging even after multiple dives. The application is very easy and mess-free.

Best anti-fog solution I've tried

I have tried sprays and wipes before, but this pen is superior. It doesn't leave streaks and the coating feels very smooth. Great product for the price point.

5 FAQ

Q: Is the formula safe for children's swim masks?

A: Absolutely. Our formula is non-toxic and skin-safe, making it suitable for children's gear. Just ensure the mask is rinsed and dried before application.

Q: How do I apply the product correctly?

A: Clean and dry your surface first. Draw a thin line across the lens with the pen, then gently spread it evenly using a soft, dry cloth until clear. Let it dry for 2 minutes before use.

Q: What is the shelf life after opening?

A: The product has a total shelf life of 24 months. Once opened, we recommend using it within 12 months for optimal performance, ensuring the cap is tightly closed after each use to prevent drying out.

Q: Can this be used on coated prescription lenses?

A: Yes, the Sulang Anti-Fog Pen is safe for use on most coated prescription lenses. However, we always recommend testing a small area first to ensure compatibility with your specific lens coating.

Q: Does this leave any residue or streaks?

A: When applied according to the instructions (spreading evenly with a dry cloth), it should not leave any residue or streaks. If streaks appear, it usually means too much product was applied; simply buff it off with a clean cloth.
