Foggy gog­gle break­down.

QI value my eye­sight too much to not wear safety glasses, gog­gles, or a face shield in the shop. But fog­ging on the lenses drives me to dis­trac­tion, es­pe­cially when wear­ing a dust mask. Do you have any rec­om­men­da­tions for keep­ing the fog at bay?

ADepend­ing on the sever­ity of the fog­ging, Mark, your so­lu­tion may be as sim­ple as buy­ing eye­wear with an anti-fog lens coat­ing. Or switch­ing to eye­wear that has greater vent­ing, or gog­gles that move the lenses far­ther from your face, al­low­ing for bet­ter air cir­cu­la­tion. Us­ing a fan to keep the air mov­ing around you can also help.

If those prac­tices don’t pro­vide re­lief, try ap­ply­ing an anti-fog treat­ment, like those be­low left. In our tests, they pre­vented fog­ging en­tirely. A num­ber of home reme­dies also work, in­clud­ing ap­ply­ing soap or shav­ing cream, and then buff­ing the lenses clear with a soft cloth. (Never use an abra­sive prod­uct such as a pa­per towel.) Wind­shield rain re­pel­lents work sim­i­larly. The old trick of rub­bing a bit of saliva on the lenses can work in a pinch, though the ef­fect can be fleet­ing.

It also helps to use a dust mask with an ex­ha­la­tion valve that chan­nels breath straight out­ward, away from your face. If you still ex­pe­ri­ence fog­ging, try the trick shown be­low.

Re­s­pi­ra­tors with sil­i­cone face seals com­pletely block ex­haled breath from reach­ing your eyes, but they can prove un­com­fort­able to wear in com­bi­na­tion with eye­wear.

For­tu­nately, th­ese so­lu­tions come with small price tags. But if you find th­ese don’t work for you, the ul­ti­mate so­lu­tion costs a few hun­dred bucks. A power air shield in­cor­po­rates a recharge­able-bat­tery-pow­ered fan that sends a con­tin­u­ous stream of fil­tered, fo­ge­lim­i­nat­ing air across your face.

Med­i­cal tape won’t win you any fash­ion con­tests, but it does ef­fec­tively block leak­age of warm, mois­ture-laden breath from the top edge of a pa­per dust mask. The ul­ti­mate in fog-bust­ing eye pro­tec­tion, a pow­ered face mask, such as this Trend Air­shield, keeps the view clear and your face cool.

Anti-fog prod­ucts come in sev­eral eco­nom­i­cal forms. You can buy 1 oz. of spray or 100 wipes for about $10. We find the wipes most con­ve­nient for small sur­faces such as gog­gle lenses.

Fog-killing wipes re­ally work. The left side of th­ese gog­gles was wiped with an anti-fog treat­ment. The right side re­ceived no treat­ment. Then, both sides were sub­jected to warm wa­ter va­por. Wiped-on prod­ucts do need to be re­newed from time to time.
