Evo Tears brand eye drops are 100% PFAS but are sold over-the-counter in Swedish pharmacies and opticians.
PFASs are a large and complex group of chemicals with over 10,000 identified substances. They are used in everything from plastic products and clothing to beauty products and frying pans. Because they are difficult to break down, they are often referred to as perpetual chemicals.
Evo Tears is marketed as a lubricating and soothing treatment for dry eyes. However, it is less clear that they contain only one ingredient – PFAS.
Daily use of the drops in the eyes produces about 120 milligrams of PFAS. This is over two million times more than the maximum tolerable intake limit via food and water.
– I would probably not use these drops myself, says chemistry professor Tuulia Hyötyläinen to Dagens ETC, which was the first to report on the eye drops.
Harmful substances
Some PFAS contain harmful substances that can negatively affect both humans and the environment. High levels have been linked to reduced fertility, high blood pressure and obesity. Studies have also shown links to poorer gross motor development in infants and ADHD in girls exposed through breast milk. Norwegian scientists warned last year that children in Norway have excessive levels of these chemicals in their bodies.
The so-called “PFAS scandal” in Kallinge attracted a lot of attention after residents ingested large amounts of the chemicals through the drinking water. For several decades, the Swedish Armed Forces had used firefighting foam containing PFAS, which leaked into the groundwater. The victims sued the municipally owned company Ronneby Miljöteknik, and after a long legal process, the Supreme Court finally awarded damages.
