- wash your glasses with soap and water, then dry them with a microfibre cloth. Soap reduces surface tension, preventing fog from sticking to the lenses.
- apply a thin layer of shaving cream to the inside of your glasses, then gently wipe it off.
- use a commercial de-misting spray.
- Improving the fit around the curve of the nose and cheeks is the best approach – mould the nose bridge at the top of your surgical mask to your face to reduce the gap that allows warm moist air up to the glasses.
- Apply some tape (eg: Micropore that’s designed for skin) to the top edge of the mask to close the gap.
- slightly moistening a tissue, folding it and placing it under the top edge of the mask.
