When the glass is foggy, many people often wait for the “fog” to clear or remove the glasses, not knowing there are other better ways.

Yuna Rapoport, an American ophthalmologist explained, the mask creates a warm airflow, creating a temperature difference between the breath and the surrounding environment. When this airflow pushes on the glasses, it will form a layer of fog, making the wearer uncomfortable.

The pandemic appeared, the demand for masks increased, becoming a daily pain for people wearing glasses. However, there are some methods to help clear glasses, even when wearing a mask, as follows.

Wash glasses with soap

Baby shampoo and hand soap reduce the surface tension of water molecules, preventing moist air from turning into a mist that surrounds the glass. Therefore, you can also apply this substance to the surface of the glass, polishing it evenly with a soft, small microfiber cloth.

Use anti-fog spray for glasses

Some commercially available antifog solutions can coat the lenses with a see-through film to help prevent fog from forming. Many are formulated for use in eyeglasses, personal protective equipment, swimming goggles and diving masks.

Note, should look for reputable brands so as not to damage the protective coating on eyeglasses. Avoid sprays used to dim car headlights because these products are harmful when in close contact with the eyes and skin.

Glass adjustment

Try pushing the glasses up on the bridge of the nose, through the mask so that if the breath escapes, it will be mixed into the air, instead of into the glasses. Try this, make sure the mask still fits the face, nose and mouth are wrapped securely.

Fix the mask with skin-safe adhesive tape

If your skin is not too sensitive, you can take a thin strip of tape to secure the mask in place and stick the top edge to prevent the glasses from fogging up.
