The Hidden Dangers of PFAS and Its Impact on Contact Lenses
Per- and polyfluoroalkyl substances (PFAS) have gained widespread attention due to their persistence in the environment and potential health risks. While PFAS are commonly associated with contamination in water and food sources, their presence in everyday products like contact lenses raises concerns about exposure and safety. Understanding the dangers of PFAS and their implications for contact lens wearers is crucial for informed decision-making and risk management.
What Are PFAS?
PFAS are a group of synthetic chemicals used in various industries for their water and stain-resistant properties. They are found in products such as non-stick cookware, waterproof clothing, food packaging, and firefighting foams. PFAS compounds are known for their persistence in the environment, earning them the nickname “forever chemicals” due to their resistance to degradation.
Dangers of PFAS Exposure
- Health Risks: Studies have linked PFAS exposure to a range of health issues, including reproductive and developmental problems, liver damage, immune system disruption, and certain types of cancer. Prolonged exposure to even low levels of PFAS can have serious consequences for human health.
- Environmental Impact: PFAS contamination can persist in soil, water, and air, leading to widespread environmental pollution. Wildlife and ecosystems can also suffer from the adverse effects of PFAS exposure, contributing to ecological imbalances.
- Regulatory Concerns: Governments and regulatory bodies worldwide are increasingly recognizing the need to regulate and reduce PFAS use due to their potential harm to human health and the environment. Efforts are underway to phase out certain PFAS compounds and limit their presence in consumer products.
PFAS in Contact Lenses
Recent studies have detected traces of PFAS in contact lenses, raising questions about their safety and impact on wearers. While the levels found in contact lenses are relatively low compared to other sources of PFAS exposure, the cumulative effects of prolonged use are a cause for concern.
- Potential Absorption: Contact lenses are designed to be comfortable and breathable, allowing them to absorb moisture and substances from the surrounding environment. This characteristic raises the possibility of PFAS absorption through contact lens wear, albeit in small amounts.
- Long-Term Exposure: Individuals who wear contact lenses regularly may experience long-term exposure to PFAS if these substances are present in their lenses. While more research is needed to understand the extent of absorption and its health implications, minimizing exposure to potentially harmful chemicals is a priority.
- Risk Mitigation: Manufacturers and regulatory agencies are exploring ways to reduce PFAS content in contact lenses and improve product safety. Consumers can also take proactive measures by choosing products that prioritize safety and transparency regarding chemical ingredients.
PFAS represent a complex challenge with far-reaching consequences for human health and the environment. As awareness grows regarding the dangers of PFAS exposure, efforts to mitigate risks and develop safer alternatives are underway. Contact lens wearers should stay informed about product composition, follow proper hygiene practices, and consult healthcare professionals for guidance on minimizing exposure to potentially harmful substances.

Brands Of Contact Lenses That While Containing PFAS, They Were The Lowest In Detected Amount
There are 6 brands of contact lenses that, when tested, did have PFAS but were at the lowest levels of all brands tested. Note: If you wear a brand that is not listed below it implies that the brand was tested and found to have higher than allowable amounts of PFAS. As such we recommend only wearing contact lenses from the sources listed above which came back at 0.000ppm
- Acuvue Oasys with Hydraclear Plus for Astigmatism (105 ppm)
- Acuvue Oasys with Hydraclear Plus with UV Blocking (113 ppm)
- Alcon Dailies TOTAL 1 One-Day Contact Lenses Water Gradient for Astigmatism (106 ppm)
- Alcon AIR OPTIX plus HydraGlyde with Smartshield Technology (119 ppm)
- Alcon Air OPTIX plus HydraGlyde for Astigmatism (173 ppm)
- Alcon Dailies MULTIFOCAL TOTAL 1 One-Day Contact Lenses Water Gradient (183 ppm).
