Covid-19 has brought all sorts of challenges we could never have imagined this time last year. If you wear glasses, you have one more challenge to deal with: your lenses fogging up every time you wear a face mask. To help ease your frustration, expert optometrist Llewellyn Anderson from Spec-Savers Umhlanga shares his top tips and tricks for keeping your spectacle lenses fog-free.
Why do glasses fog up when wearing a face mask?
Due to limited airflow, fogging occurs when wearing a medical or cloth face mask as your breath mostly escapes from the top of your mask. When you exhale, your warm breath comes into contact with your cooler lenses, causing condensation which steams up your lenses and clouds your vision.
Anderson shares his 5 tips for wearing a face mask without your glasses fogging up:
Make sure your mask fits snugly
Secure the mask around your nose
Securing your mask around your nose is another way to limit the amount of breath that escapes upwards. Try moving your mask further up your nose and resting your glasses on top of it to help seal the mask. Or try using surgical tape, a pipe cleaner or even a plaster to secure the mask to the bridge of your nose. This helps form a seal to prevent your breath from escaping upwards.
Clean your lenses
Use an anti-fog lens wipe or spray on your lenses
Consider anti-fog lenses
Anderson says that, while there is no miracle solution for this annoying problem, most of his clients have had success with one or more of these tips. “But if all else fails, or you’re not in the market for anti-fog lenses right now, it might be worth switching to contact lenses until masking up is a thing of the past. Especially if your job requires visual acuity, or you need to do a lot of driving while wearing a mask.”
