Having had a career in the Optical Profession I have learned that so called anti fogging is a very fragile coating which will not survive ANY rubbing or surface handling…… Goggles fog up because (invariably) the interior air is (body temp?) is warmer than the water or air temp. Saliva contains liquid which has a lower surface tension and once manufacturing/ moulding residue is removed becomes an excellent anti-fogging agent – takes about 5 or 6 sessions of licking to achieve this and is my choice for competitive pool goggle (small rimless Monte Barra or similar) where long term comfort or 20/20 vision is not the priority..
In conclusion the large clear rimmed Blue Seventy goggle is my undisputed choice for Open Water swims, over any other available!!!! In addition to aforementioned discussion, The excellent wide angle offers little peripheral visual restriction and no other treatment than some drops of Dish Washing liquid + luke warm water (to help dissolve the salt) rinsed inside an out and just shaken freely (no no touching or rubbing) and left to air dry. Just simple dip or after donning “drown with sea or lake” – get your aiming point +/- predicted cross track influences and goforrit….
Thank you for the tip, very much appreciated
I disagree, with the price of some goggles and the ” anti fog” I should just be able to put them on and swim.
Cheaper goggles are better for this.
Never touch the inside of the lenses with your fingers. it distories the anti goggles.
Always buy a new pair and test them before a big race.
