The Scicon Sports Anti Fog Lens Cleaner Spray is designed to reduce fogging up of lenses. Cleans and rejuvenates all Scicon Sports lenses while enhancing the anti-fog properties. How to use it: Spray a light mist on the surface of the lens. Immediately wipe with a clean, dry, and lint-free microfibre cloth. Note: No anti-fog can eliminate 100% of fogging in extreme cold and/or humid conditions. Frequently wiping lenses without anti-fog spray (i.e., during race/practice) will remove reduce anti-fog effectiveness gradually. Apply regularly to the inside and outside of the lenses to keep them clean for maximum visibility. WARNING: Not intended for human consumption. Keep spray clear from eyes and never apply while wearing glasses. Do not ingest. Keep out of reach of children. In case of contact with eyes, rinse thoroughly with water and seek medical attention if itching persists.
