How to Stop Foggy Glasses while Wearing Masks

Face masks were already a part of Asian culture. But as the pandemic hit, face masks became mandatory for everyone.

And this became a problem for people who wear glasses.

Foggy lenses were always a problem for eyeglass wearers, but we’ve never noticed how inconvenient it is until we had to deal with it every day.

While we can’t control what’s going on around us, the good news is, we can avoid foggy glasses!

Why do my glasses fog up?

Fog is a form of condensation. Condensation happens when warm air hits a cool surface. This causes misty droplets of water to form on a surface.

Condensation on your glasses can happen when you step out of an air-conditioned space into Singapore’s humid sunny conditions. When your warm breath escapes through the top of the mask, it hits the cooler lenses of your glasses and causes them to fog up.

There are specialised anti-fog glasses that prevent glasses fogging, but you probably don’t want to buy a new pair of glasses just for face mask use.

So keep on reading for tips on preventing foggy glasses and how to make some anti-fog treatments!

Tips and tricks for preventing foggy glasses

Find the right face mask fit

Masks that don’t fit your face well allow for warm, moist breath to escape. That warm air hits your glasses and instantly makes your glasses fog.

The solution is easier than you can imagine: look for a face mask with a better fit!

While one-size-fits-all masks are convenient, they don’t always have the greatest fit, especially around your nose. Plus, better-fitting masks greatly improve protection against COVID-19.

So, if your glasses are fogging while you’re wearing a face mask, it may be because your mask doesn’t fit properly. You may want to look for an adjustable nose clip to add to your mask.

Once your mask is in place, pinch the nose clip to tighten the mask over your nose bridge. A snug-fitting mask will help keep puffs of warm breath from fogging your lenses.

 

Spritz an anti-fog spray

Anti Fog Spray for Eyeglass Lens

If your glasses are still fogging, then you might want to use an anti-fog spray.

Several commercially available anti-fog sprays can usually be found at your local optical shop. These sprays work by coating your spectacle lenses with a thin film that keeps fog from forming. Many are formulated for use on eyeglasses, personal protective equipment, swim goggles, and diving masks.

However, if you want to DIY your own lens spray, we have a solution for you!

This recipe couldn’t be simpler. All you need is water, white vinegar and a spray bottle. Here are the instructions:

  1. Mix 3 parts water to 1 part vinegar in the spray bottle.
  2. Apply it to both sides of the lenses.
  3. Gently wipe the cleaner off with a lint-free cloth.
  4. Wait a minute to air dry before putting your glasses back on.

Be careful not to spray the cleaner in your eyes; it will burn.

Wash with soapy water

Did you know that you can prevent glasses from fogging with soapy water?

This advice comes from the medical journal Annals of the Royal College of Surgeons of England, courtesy of two doctors. And if their anti-fogging trick can work in the emergency room, it can certainly work in the grocery store.

This simple method works because soapy water leaves a layer of soap molecules on your glasses, forming a thin film with anti-fogging properties.

Just before you don your specs, wash them with soapy water.

Make sure to use a mild soap like baby shampoo to prevent damage to the protective coatings of your prescription lenses. It’s also better to use warm water as it is more effective at removing grease stains.

Take your time to wash your glasses, ensuring that you are gentle when handling them.

After, use a soft cloth to absorb any excess liquid on the lenses. If you have time, leave them to air dry.

Block gaps between the top of the mask with a tissue

If you need a solution fast, reach for some tissue, paper towels or a small piece of cloth.

Then try these steps:

  1. Fold the tissue into a slender, long piece, and place it directly under the top edge of the mask.
  2. Secure your mask snugly by placing your eyeglasses’ bridge over the mas. This is so the tissue will stay in place.

It’s not a perfect solution, but it will prevent spectacle lenses misting if you’re in a pinch!

Takeaway

Stopping glasses from fogging is all about preventing air from escaping from the top of your mask. Many solutions for foggy eyeglasses are easy to test and inexpensive.
