How to keep your glasses fog-free while wearing a face mask

It is not uncommon to hear spectacle lens wearers complain about foggy lenses, especially since wearing a mask in public has become compulsory. You may have heard of numerous possible solutions for this frustrating problem: from making sure your mask fits snugly to securing the mask around your nose with surgical tape.

But do any of these solutions really work? Maybe it is important to first establish why glasses fog up when wearing a face mask.

Why do glasses fog up when wearing a face mask?

Due to the limited airflow, glasses fogging up tends to be more common when wearing a medical or cloth face mask because your breath mostly escapes from the top of your mask. When you exhale, your warm breath comes into contact with your cooler lenses, which steams up your lenses and clouds your vision. This steam also creates excess moisture around your glasses which reduces the grip of your nose pads, and makes it easy for them to slip down your face.

It is certainly true that a tight-fitting mask not only helps to keep you protected against any airborne particles, but it also stops too much breath from escaping and fogging your lenses.  It is also a good idea to try resting your glasses on top of your mask in order to help seal the mask. Other tips include trying to use a small piece of surgical tape to secure the mask to the bridge of your nose, as this will also help to form a seal to prevent your breath from escaping upwards. 

Spectacle lenses that haven’t been cleaned properly also tends to fog up quicker. Experts advise using a good cleaning spray and a clean glasses cloth to clean your glasses and doing at least once a day. 

Fortunately, there is a much more convenient, easier and longer-lasting way to keep your lenses fog free: Applying ZEISS AntiFOG spray to your lenses!

The anti-fog spray and cloth which, when used together, can ensure clearer, more comfortable vision, especially when wearing a mask. The spray is not only effective, but also easy and safe to use.

The product, forming part of ZEISS’ lens cleaning range, is applied directly to the lens and then dried with the accompanying anti-fog cloth. ZEISS AntiFOG spray promises to keep lenses fog free for up to 72 hours!

How does it work?

The anti-fog spray leaves behind a thin hydrophilic film (comparable with a temporary additional coating) on your lenses. This ensures that fine, condensed water droplets do not adhere to the lens surface, preventing lenses from fogging. The spray will work equally well on sunglasses, goggles and camera lenses.

ZEISS AntiFOG spray is available at all Mellins i.Style branches countrywide and online at R164 per kit.
