Most of us have experienced this phenomenon. You put a protective mask on when going in public and then it begins. You look for the defroster button you would use on your windshield to clear the fog-but it is not there. Why do your glasses fog up? It’s simple. The mask directs your breath upward instead of straight forward.
One expert suggests the following to help to reduce the problem:
The main ingredients are soap and water. The advice comes from the medical journal Annals of the Royal College of Surgeons of England.
After washing your hands with soap and water, suds up the lenses. Then rinse your glasses under mildly warm water. Do not leave a soap film on the lenses. Dry your lenses. This action should not replicate what you do when you are drying a dish-you could scratch the lenses. You should gently pat the lens dry with a soft cloth or lens cloth.
So what is the magic here: According to the Journal report the soap and water act like a film that reduces surface tension on your glasses. The mix allows the water molecules from your breath to distribute evenly, rather than cluster on your lens creating fog.
Another tip to prevent fogging: Wear your glasses a little lower on your nose as long as it’s not affecting your vision. This seems to help in the defogging process.
The best advice is to check with your eyewear professional.
Just how effective are these suggestions? We will leave that up to you to decide. Write to firstname.lastname@example.org to let us know if you no longer are in “the fog”.
