Contact lenses are now an essential component of modern vision correction, providing comfort and convenience to millions of people throughout the world. The Guardian reports that a recent study has uncovered alarming discoveries on the presence of cancer-causing “forever chemicals” in several kinds of contact lenses. These compounds, often referred to as per- and polyfluoroalkyl substances (PFAS), have been associated with a variety of diseases, including cancer.
Due to its resistance to heat, water, and oil, PFAS are synthetic substances that are frequently employed in the production of several consumer products. However, there are serious concerns due to their enduring presence in the environment and possible health dangers. In the investigation, which was carried out by a group of academics, PFAS was found in numerous brands and varieties of contact lenses.
24 distinct contact lenses from different manufacturers were examined by the research team
24 distinct contact lenses from different manufacturers were examined by the research team, who discovered that every single one of them had at least one form of PFAS. These substances are often added to lenses during production to increase their flexibility, toughness, and water resistance. Although the presence of PFAS in contact lenses would not immediately be dangerous, prolonged exposure to these substances is of concern.
PFAS exposure has been linked to a number of health hazards, including cancer, hormonal imbalances, immune system problems, and developmental problems. The term “forever chemicals” refers to substances that are resistant to deterioration in both the environment and the body, which causes them to accumulate over time.
The long-term effects of exposure to PFAS are still unknown
It is significant to note that the contact lenses had only a little amount of PFAS. Even in low quantities, the long-term effects of exposure to these substances are still unknown. Furthermore, neither the potential health effects of such exposure nor the transfer of PFAS from the lenses into the eye were examined in the study.
Further investigation is required to determine the scope of the issue given the widespread usage of contact lenses and the potential health hazards linked to PFAS exposure. To reduce or completely eradicate the presence of PFAS in their goods, manufacturers should prioritize the development of safer alternatives and use stricter quality control procedures.
