New analysis has revealed that many mushy contact lenses from the US are made up of compounds linked to a bunch of well being points together with most cancers, liver and kidney illness, autoimmune issues and fertility issues.
Fluoropolymers are by definition described as PFAS or “forever chemicals” and a few contact lenses are discovered to have extraordinarily excessive ranges of natural flueronic, a marker of PFAS, in every.
They are known as “forever chemicals” as a result of they don’t naturally break down, and are present in client merchandise that resist water, stains and warmth.
Researchers from plenty of American universities together with North Carolina State University examined 18 totally different pairs of soppy contact lenses to see in the event that they contained PFAS.
At least half had been day by day lenses.
The testing, commissioned by Mamavation and Environmental Health News public well being blogs and carried out at an EPA-approved lab, looked for traces of natural flourine in lenses by manufacturers Acuvue, Alcon and Coopervision.
Scott Belcher, a North Carolina State University researcher, instructed The Guardian “you could consider the lenses almost pure PFAS”.
Flourine was detected between 105 elements per million (ppm) to twenty,700ppm.
This means the entire examined contact lenses exceeded 100 ppm, which is equal to 100,000,000 ppt, or 50,000 instances greater than the best degree deemed secure in ingesting water by the EPA.
The three lenses with the best quantities of natural fluorine had been Alcon Air Optix (No Hydraglide) for Astigmatism (20,000ppm), Alcon Air Optix Colors with Smartshield Technology (20,700ppm) and Alcon Total30 Contact Lenses for Daily Wear (20,400ppm).
Among the bottom ranges included Acuvue Oasys with Hydraclear Plus with UV Blocking (113ppm) and Alcon Dailies Total One-Day Water Gradient for Astigmatism (106ppm).
The chemical compounds are additionally so extensively used that they are often unintentionally added to merchandise all through the provision chain.
Independent and tutorial researchers in recent times have discovered them in a spread of merchandise from bathroom paper to plastic meals containers to fruit juice.
