Do you have to clean the lenses on these like scuba mask? will they fog up?
CHARLES B You do need to use an "anti-fog" solution to avoid fogging. Either very diluted dish washing soap or saliva will work well.
MIRIAM T I adore the Aqua Sphere Kaiman clear lens goggles, they provide the best visibility and are very comfortable. I do rinse them off after lap swimming using a non greasy soap. They can fog up a bit but much less than many of the other goggles I've used.
ALEXANDER M These act like swim goggles, not like as scuba mask, with regard to fogging. I do nothing to them before a workout - just put them on. Sometimes, toward the end of a workout, I rinse then out with the pool water - no different than any other swim goggles in my experience (and actually less fogging than most swim goggles).
CLAIRE C I don't have a problem with them fogging up, especially when new. I don't clean them, I just rinse them with water and ever so often use spit before swimming.
PAMELA P I'm a spitter. I've tried all sorts of anti-fog stuff on masks and goggles alike, and nothing ever works as well as good old-fashioned saliva. I rinse the chlorine off them after use, and keep them in a soft case, wash with shampoo from time to time, but that's it, and I've always done that with all goggles and masks.
JACKIE P No they are pre treated with Anti fog
