How to stop your glasses fogging up

With face masks becoming the new essential fashion trend and no signs of a vaccine being certified anytime soon, we have all been adjusting to the new "Covid-19 norm." For our own safety, the government has enforced the UK public that the use of face mask is mandatory in the place listed below.


  • public transport 
  • shops and supermarkets 
  • shopping centres 
  • auction houses
  • premises providing professional, legal or financial services 
  • premises providing beauty treatments and personal care 
  • The vets
  • Entertainment venues 
  • libraries 
  • places of worship
  • funeral service providers
  • community centres, youth centres and social clubs
  • exhibition halls and conference centres
  • public areas in hotels and hostels
  • storage and distribution facilities


But with the extensive use of masks, it has brought on a new glasses struggle; they keep fogging up! Whilst adapting to (slightly claustrophobic) face coverings, it is affecting those who rely on eyeglasses as they are now unable to see due to the unwanted mist. 


Why are my glasses fogging up when I wear a face mask?

To put it simply, when you breathe out your warm carbon dioxide breath needs to escape. But when you have a face mask blocking the way, it really has only one place to go...up towards your eyes! For those of you who are wearing glasses, you'll start to notice things will begin to fog up. This is due to the tiny droplets produced when the warm vapour from your breath hits your cool lenses. 


Thankfully we are here to share a few tips on how to avoid your glasses fogging up whilst wearing a mask.


Warm, soapy, water.

Washing your lenses with warm soapy water will eliminate any excess moisture that may already be on your glasses. Do this before you apply your face mask or covering. Once rinsed of any remaining soap you can dry them with a microfiber cloth. These usually come with the glasses at the time of purchase. 

You can also use shaving cream or baby shampoo to wash with, but best to use soap to avoid any risk of damage to your eyeglasses.

Tape the mask

You may prefer to use sports tape and place it on the bridge of your nose and cheeks. Apply the top of the face mask over the tape and press firmly. This will reduce the airflow rising up towards your glasses.


We advise you not to use duct tape on your skin as this may cause discomfort and injury.


Make sure the face mask is secured well

To get the best use out of your facemask, you will want to make sure it fits your face well and avoid being loose. When your mask is hanging off your face loosely, it encourages airflow to rise towards your glasses -cue the fogging. You can adjust the length of the string by twisting it once and then placing it around your ears.


You may also wish to purchase a face mask that includes a moldable element, such as a metal strip across the nose which allows you to mould the top of your mask to your nose, minimising airflow upwards. 

De-fogging products

Before putting on your glasses, apply over-the-counter anti-fogging products to the lenses regularly. Anti-fogging products can come in the form of spray, waxes, and gel, so you have various options to choose from. One application isn't a permanent solution, but it will help prevent fogging in short time frame activities such as shopping or travelling on public transport.


Laser Vision Correction Treatment

If you want a more permanent solution, laser eye surgery (in the form of LASIK/LASEK surgery) or lens surgery can help you get rid of your glasses altogether. You won't have to deal with the hassle of fogged up lenses when wearing a face mask, and you'll be able to see the world clearly with your own eyes.
