Important:  Do not wash the cloth—washing strips the activator and reduces effectiveness.

1. Remove the Anti-fog cloth from the zipper bag. Keep the bag clean and dry.
2. Evenly rub each lens (both sides) with the Smart Textile using light, uniform strokes.
3. Blow gently on the lens to confirm activation—your lens should resist fogging.
4. After use, seal the bag tightly to preserve the cloth’s activator.

Important: The cloth activator is also used as the cleaning cloth for your glasses.

1. Rinse exterior lens surfaces thoroughly with clean, lukewarm water.
2. If needed, gently rub exterior surfaces with clean fingertips under water to loosen debris/oils.
3. Rinse again (exterior surfaces).
4. Air-dry or pat dry the exterior with a clean microfiber (no paper towels).
5. Reactivate with the Cloth

• Still fogging after activation? Rinse exterior surfaces with water → dry → activate again. If it persists, the cloth may be depleted—replace it.
• Smears/rainbow sheen? Rinse the exterior thoroughly with water, dry, then reactivate.
• One lens clearer than the other? Ensure you’re wiping both sides during activation evenly

The cloth gradually runs out of activator. Replace it every 3 months or up to ~450 activations—whichever comes first.

Keep the cloth unwashed and sealed in its zipper bag between uses.

• Performance can vary depending on lens type, environment, and usage conditions.
• Very hot environments (e.g., saunas) are not recommended for the lenses.
• Very cold environments (around –20 °C / –4 °F) can reduce duration—reactivate more often as needed.
• High humidity, heavy perspiration, or rapid temperature swings may require more frequent reactivation.
