Although most modern goggles come with defogger, this coating wears off with exposure to pool water, sweat, and skin oils. Aqua Sphere Anti-Fog Solution prevents fogging of swim goggles and masks caused by a rise in body temperature. Use it to extend the life of the pre-applied anti-fog coating that comes standard on most goggles. Clean and dry your goggles thoroughly. Then add a drop of solution to the inner lenses of your goggle and use your finger to spread it on the lens. Let stand for two minutes, then rinse in fresh water.
I bought a bottle of this stuff along with some other items that I had used before. I thought that I would try it. I have used it four or five times on a pair of Aqua Sphere goggles, and it does not work. I end up spitting in them after a couple of laps. Not going to buy it again.
If you have tried the REST... ....then TRY THE BEST ! I have used these Anti-fog drops for Years ! I have been a swimmer-diver for 40 years...and turn everyone onto these drops.! THEY WORK !! And the price is reasonable ! GET THEM NOW !! YOU WILL BE GLAD YOU DID !! (^.^)
This anti-fog works good and doesn't irritate my eyes Good price for a good product.
I have been a USMasters swimmer for 40 years. That represents a lot of googles both good and bad. Possibly, because of the physiology of my eyes anti-fog goggles have never worked for me. I have always had to resort to adding some type of liquid ( including spit ) to my goggles. After all this time , I have found the answer with Aqua Sphere Anti-Fog. Simple to use and does not seem to have an adverse affect on anti -fog goggle lenses. Other products I've tried either do not last through a workout or tend to damage ( in some cases even etch) the lenses. I strongly suggest giving Aqua Sphere Goggle / Mask Anti-Fog a try.
