Choose the anti-fog spray based on the application. Regular types are fine for your everyday goggles and eyeglasses.

But you may need a different type of defogger for your diving mask or swim goggles as you’ll need to see underwater without having the lenses fogged up.

2. Clean and dry the lenses before you apply the spray

Clean your lenses with baby shampoo or soapy water. Then run the glasses under clean tap water and dry using a soft piece of cloth. You can use lens wet wipes if you have them handy. The anti-fog treatment works on clean glasses way better than dirty glasses.

3. Shake the spray bottle

Once the lenses are clean and dry, don’t forget to shake the bottle before you spray the solution onto the lenses.

First, apply the solution onto the inside lenses and then onto the outside. Make sure the solution reaches every corner of the glass thoroughly.

Next up, wipe the lenses with a clean cloth. Be gentle as you buff the lenses so the anti-fog formula coats well.

Some solutions may require you to wait for a minute before you wipe it. Don’t forget to go through the instructions on the spray bottle to use the right solution.

6. Test the lenses before you jump into action

Test the lenses before you jump into action

Take your lenses to a hot water basin. Turn on the faucet, let the steam pass over your goggles and see how the formula is working out.

Of course, you can try whatever way you like to test it. Now you can hit the waters once you’re satisfied with the result.

  1. First clean the entire outer and interior surface of the windscreen thoroughly and wipe it to dry.
  2. Take a good amount of the anti-fog solution into a piece of soft cotton fabric. Rub the solution all over the windscreen from the inside and outside and then buff in a circular motion to make it dry.

Note: Do not get the solution on painted surfaces or areas that are not transparent. Make sure the anti-fog solution doesn’t spill on the inside components that may have paint on them.

How do you defog your glasses when wearing a face mask?

How do you defog your glasses when wearing a face mask

It’s unquestionably frustrating when your eyeglasses fog up because you’re wearing a face mask and trying to save yourself from airborne particles, including the coronavirus. The breathing condensation may seep through your mask and reach the lenses if it’s not fitted on your face as it should be.

Fogging may take place depending on the type of fabric your face mask is made of or the type of activity you do.

Pro tips to prevent fogging on the lenses when wearing a mask

  • Spray your anti-fog formula on the inside and outside and build up a protective layer on your lenses.
  • Hold your eyewear at an angle and spray the anti-fog formula from about 10” away. This will allow the solution to disperse across the glasses more consistently
  • Leave the anti-fog solution on the lenses for 2-3 minutes and then go on to buff it lightly with a lint-free piece of fabric until they’re clear
  • Try wearing breathable, environmentally friendly cloth masks whenever possible and avoid disposable paper masks
  • Make sure the nose fitting is nice and tight to stop the condensation from oozing up to your eyes
  • You may want to adjust your breathing style as well. Breathe in through your mouth and breathe out down through your nose

Things to Remember When Using an Anti-fog Spray

Things to remember when using an anti-fog spray

  • Diving masks and swim goggles require special anti-fog treatment

A standard anti-fog solution may wash off easily due to its constant contact with water. Get the anti-fog treatment particularly prepared for these underwater masks and eyewear.

  • Complete defogging may not be possible in harsh weather conditions

You should not expect a flawless result from the anti-fog spray in extreme weather conditions, such as storms and heavy snowfalls. You may need to apply the solution more frequently to go through the day.

  • Consider carrying your anti-fog spray

It’s a good idea to take precautions and always carry a small spray bottle with you, especially when the weather is rough. Water can remove most anti-fog coatings pretty easily. Make sure you’re able to reapply the formula each time you need it.

  • Defog your eyewear before each round in a game or practice

If you’re a professional swimmer, don’t forget to take a moment to give your goggles an anti-fog treatment when it’s your big event. It’ll make you see more and keep you safer and faster in the water.

  • Spray more than once a day when fog is a constant challenge

Be it the weather or your activities, spray several times a day if you find the lenses are fogging up too much. It might be necessary for you to use the formula a few times a day in case you work in an environment related to manufacturing or construction.

A quick look at the benefits of using anti-fog spray

FAQs

1. Does anti-fog work?

Ans: Yes, it does! The anti-fog treatment works by reducing surface tension and creating a “non-scattering film of water” over your lenses and glasses that modifies the rate of wetting.  These solutions work as a hydrophilic surface or a surfactant film.

2. How long does anti-fog coating last?

Ans: On average, the anti-fog coating lasts about 3-6 days in normal conditions. Most anti-fog solutions can hardly get you through the day when the weather shows its roughest side.
