It may seem like a small matter, but one of the most common annoyances with wearing masks is how it can fog up glasses. The American Academy of Ophthalmology (AAO) explains that this is caused when warm breath escapes from the top of your mask and lands on the cooler surface of your lens.
The following tips may help prevent your face mask from fogging up your eyewear:
- Make sure your mask fits your face. An ill-fitting mask will allow warm air to escape from the top and fog up your lenses. You can buy masks with a nose bridge or masks that can be shaped (such as those with an inside wire at the top) to form to the face, and close that gap which allows the warm air to escape.
- Push your glasses forward on your nose to allow more air to circulate, and keep your breath from fogging up the lenses.
- Try pulling your mask up over your nose and rest your glasses on top of it to block the air from escaping and causing fogging. If you try this method, make sure your mask still fits properly over your face to completely cover your nose and mouth.
- Wipe your lenses with an anti-fogging solution, or gently wash your lenses with soap and water before wearing them to help keep water droplets from building up and fogging your lenses.
