Why Do Glasses Fog Up?
There are several factors that cause your glasses to fog up — one of which is ambient heat, in other words, the actual temperature in your surrounding environment. Eyelashes that touch the lens can cause fogging, as well as tight-fitting frames that touch the cheeks (many plastic frames cause this problem), which impede proper airflow. Lastly, high humidity and the sweat and moisture that accompany overexertion/ exercise can also trigger foggy lenses.
Ultimately, glasses cloud over due to moisture in the air condensing on the cold surface of your lenses.
Now that you know the most common reasons why your glasses fog up, it’s time to read about some possible solutions. Below are a few tips to help keep your lenses clear year-round.
Tips to Steer Clear of Cloudy Specs
1. Invest in Anti-Fog Coating
Anti-fog coating blocks out moisture that would normally stick to your lenses, by creating a surface layer that repels water and mist. An optician applies the treatment to both sides of the lens in order to prevent fogging so you can see clearly in any climate or environment.

2. Use Anti-Fog Wipes, Sprays, or Creams
Commercial anti-fog products are an alternative to lens coatings. These products, typically sold in either gel or spray form, are specially designed to prevent condensation and moisture from building up on your lenses. Apply the product as directed on the packaging and remove it with the supplied cloth, wipe or towelette. If a cloth wasn’t included in the box, use a scratch-free cloth.
Aside from the gel or spray, you can use anti-fog wipes. These pre-treated napkins are perfect for those who are on the go.
3. Move Your Glasses Further Away from Your Face
Eyeglasses tend to trap moisture and heat, particularly if they are positioned close to your eyes or face, which increases the buildup of fog on your lenses. Consider adjusting the position of your eyewear by pushing your glasses slightly further down your nose. It will stimulate proper air circulation, thereby reducing fog accumulation.
4. Swap Glasses for Contact Lenses
If contacts are an option for you, you might want to wear them on those cold days, to avoid foggy glasses syndrome (yeah, that’s a made-up term).
