If your mask doesn’t reach up to the bridge of your nose, consider buying a bigger one that gives you better coverage.

If your mask doesn’t have a nose wire, you shape the top of the mask with a pipe cleaner or attach an adhesive nose wire. A mask fitter or brace that sits on top of your mask also keeps it tight against your face.

If your mask has a set of upper and lower ties, loop the upper ties below your ear and the lower ties above your ear for a tighter fit.

Attach a strap to the arms of your glasses so they won’t fall down. Wearing your glasses lower could slightly affect how you see through your lenses. If you have a strong prescription, you may want to try a different fix.

If your mask still fits loosely, then the warm air might move around the tissue.

Avoid using any masking or duct tape since the adhesive could irritate your skin.

Cleaning your glasses with baby shampoo, toothpaste, or shaving cream could damage the lenses, so stick with mild hand soap.

You can also buy anti-fog wipes if you don’t want to use a spray.

This is especially important if you have prescription bifocal or varifocal lenses since they need to sit in a certain spot to help you see. Ask your optometrist about getting anti-fog lenses for your glasses since they have a special coating that prevents moisture from sticking on them.
