Intended Use: Apply this cleaner and anti-fog on swim goggles, snorkel and dive masks, non-AR eyeglasses, sunglasses, face shields, and safety glasses 
Treat multiple goggles, masks, and eyeglasses with this concentrated, alcohol-free anti-fog; one 0.5 fl oz bottle pumps out 150 sprays 
Use easily for clear and clean vision that’s effective for hours on glass, plastic, vinyl, and acrylic lenses (e.g., prescription, transition, photochromatic, and polarized lenses) 
For best results on eyeglasses: spray on and allow to dry for a couple of minutes at first application, then lightly buff with cloth; repeat to improve effectiveness
