You didn't try all the anti-fog advices on this forum because a few solutions make it physically impossible for the exhaled air to reach the eyes i gave one solution myself which is used in some arctic expeditions and saw a few more solutions on this forum which should reach the same results.
I gave a corrective solution which should be combined with the other solutions. Some goggles used by the military with a real integrated fan

The preventive solution i gave was to cut a flexible plastic sheet the size of your face. Cut holes for your eyes and put the sheet on your face directly under the goggles
In some arctic expeditions they sew the sheet directly to the bottom of the goggles (above the mouth).
In both case the exhaled air simply can't reach the eyes directly if done properly.
Another solution i saw on this forum was to use a mask respirator without filter and add tubes to move the exhaled breath away and warm the incoming air. (Not sure on this one)
