Tests of 18 popular types of contact lenses revealed extremely high levels of organic fluoride. This chemical is believed to be linked to various health issues.
Notice to contact lens wearers. According to new research, some are linked to health problems due to their content of “per- and polyfluoroalkyls”, better known as PFAS. These long-lived chemicals have been widely used since the 1950s in various industrial fields and consumer products.
As reported by the New York Post, researchers from several American universities, including North Carolina State University, tested 18 different pairs of soft contact lenses from major brands including Acuvue, Alcon and Coopervision, sold in France. And this, in order to know if they contained PFAS. Note that at least half were daily lenses.
What alternatives?
To their surprise, the tests showed the presence of fluoropolymers, organic fluorine which is by definition a PFAS. At this time, it is difficult to know precisely what health consequences this level of exposure of the eyes to chemicals may have, because no studies have been done on how the eyes absorb PFAS from lenses. As explained, there is little consumers can do to protect themselves beyond wearing glasses or talking to their doctor about possible alternatives.
As a reminder, PFAS are a class of approximately 14,000 chemicals typically used to make thousands of consumer products resistant to water, stains and heat. They’re called “eternal chemicals” because they don’t break down naturally and are linked to cancer, fetal complications, liver disease, kidney disease, autoimmune disorders and other problems. serious health.
