Anti-fogging agents for glasses: warning of toxic ingredients


Share post:

If it’s cold outside, the glasses can quickly fog up when you put on the face mask. Chemical anti-fogging agents promise a remedy. However, consumer advocates are warning that the sprays, gels, foams or wipes can be harmful to health.

Anti-fogging agents warning: Wearing mouth and nose protection is an important measure to contain the corona pandemic. However, there is a problem for those who wear glasses: If it is cold outside, the glasses fog up when the mask is put on and the wearer can no longer see anything. For this reason, various anti-fogging agents are available on the market in the form of sprays, gels, foams or wipes. However, anti-fogging agents often contain substances that are harmful to health and the environment, warns the consumer advice center.

Anti-fogging agents in brief

  • In the case of anti-fogging agents for glasses, there is often no indication of the ingredients. It is better not to buy such products.
  • If information is available, pay attention to terms such as “-fluor” or “-fluoro”, “hydrophobic” and “water-repellent”. They can be a reference to contained PFAS.
  • Glasses fog up less often if you wear the glasses over a tight-fitting mask and treat them with a thin film of detergent or soap – provided the glasses can tolerate it.

Everyone who wears glasses currently knows the problem: As soon as the protective mask against corona is put on outside at low temperatures, the glasses fog up. Agents against the unwanted fog on the glasses are offered in optician shops, drug stores, sports shops and online shops as spray, gel, foam or cloth. These often contain substances that are particularly harmful to health and the environment, per- and polyfluorinated alkyl substances (PFAS).

Too much toxic chemistry

In order for anti-fogging agents to have a moisture-repellent effect, sometimes harmful PFAS (per- and polyfluoroalkyl substances) are used. These substances can also be found in some waterproofing sprays and sometimes in weatherproof outdoor clothing. PFAS spread through their use in the environment – where they are hardly degradable . They are harmful to health and can accumulate in plants, animals and the human body. The EU Commission is planning to drastically limit the use of this entire group of chemicals because of their harmfulness.

Observe information on the product

If ” -fluor ” or ” -fluoro ” appears in the ingredient list, it is likely to contain PFAS. Terms such as “ hydrophobic ” or “ water-repellent ” in the description can also refer to PFAS.

But the ingredients of anti-fogging agents are unfortunately often not listed on the packaging, on the offer page on the Internet or in the package insert. Without this information, however, you cannot tell whether it is a product containing harmful substances or not. If there is no information about the ingredients, you should not buy the fog killer for eyeglass lenses.

Allergy sufferers should be particularly careful

Water-based anti-fogging agents can also contain preservatives, some of which can cause contact allergies. People who have already had an allergic reaction to it should always compare the ingredients with their allergy passport. After all, parts of the treated glasses touch the skin for a long time.

Dispose of properly

Anyone who has already bought PFAS-containing agents and would like to get rid of them should by no means pour them down the drain, but rather take them to the local waste disposal company for the collection of pollutants.

Home remedies for a clear view

Glasses do not fog up so easily if the corona protective mask fits snugly at the top and the glasses are worn over the mask. Even a very thin film of detergent or soap on the glasses can protect against fogging to a certain extent. Depending on the coating and type of glasses, you should ask your optician beforehand to be on the safe side whether the visual aids can be attacked by the use of soap or washing-up liquid.
