The Issue:
Independent testing has detected high levels of organic fluorine, a marker for PFAS, in several popular soft contact lenses.
The Risk:
The eye absorbs chemicals rapidly through the tear film—bypassing the liver and entering systemic circulation more directly.
The Solution:
Moody Blue lenses undergo third-party organic fluorine testing and are certified 100% PFAS-Free, made with clean silicone hydrogel and no fluorinated additives.
The Invisible Ingredient You Never Agreed To Put in Your Eyes
Most people check ingredients on food labels. Many avoid harmful chemicals in skincare. But almost no one checks what sits directly on their cornea for 12–14 hours a day.
Your eyes are among the most absorbent organs in your body — yet a growing concern in the optometry world is drawing attention: PFAS found inside certain soft contact lenses.
A recent consumer investigation reported by The Guardian revealed high levels of organic fluorine in multiple popular brands. These are the same chemicals used in non-stick pans — now showing up in Class II medical devices placed directly on the eye
At Moody Contacts, we believe clear vision should never come with a chemical compromise. That’s why our Moody Blue collection is engineered to be 100% PFAS-Free, backed by material science and verified testing.
This guide breaks down everything you should know — and what to avoid.
What Are PFAS Chemicals? (“Forever Chemicals,” Explained )
PFAS stands for Per- and Polyfluoroalkyl Substances. It refers to a group of over 12,000 man-made chemicals used widely for their resistance to heat, oil, and water
Where PFAS are commonly found:
-
Non-stick cookware
-
Water-repellent clothing
-
Stain-resistant fabrics
-
Fast-food packaging
-
And now: detected in up to 18 popular brands of contact lenses
The United States Environmental Protection Agency (EPA) states that PFAS do not break down naturally due to their ultra-strong carbon-fluorine bonds. Instead, they accumulate — both in the environment and inside the human body. This is why they are often called “Forever Chemicals.”
Why PFAS in Contact Lenses Is Especially Concerning (Ocular Toxicity)
While PFAS exposure from cookware is troubling, exposure via contact lenses is a completely different risk category. Here’s why:
-
The Cornea Absorbs Chemicals Directly
Peer-reviewed research available on PubMed indicates that the eye’s surface is a highly permeable mucous membrane. Unlike skin, the cornea has direct biochemical uptake pathways.
-
Bypassing the Body’s Detox System
Unlike swallowed substances (which pass through the liver), anything placed on the eye can enter the bloodstream through the tear drainage system and nasolacrimal duct. This means even trace PFAS placed on the eye daily may accumulate systemically.
-
Health Warnings from Major Agencies
The Centers for Disease Control (CDC) and the Agency for Toxic Substances and Disease Registry (ATSDR) list PFAS exposure as linked to:
-
Hormonal disruption (Endocrine disruptors)
-
Immune system suppression
-
Reproductive and developmental issues
-
Elevated cholesterol
Moody Blue’s PFAS-Free Standard: Built for Modern Eye Health
We took a proactive, non toxic approach. Instead of using chemical coatings, we rely on advanced materials.
1. 100% PFAS-Free Certified
We conduct third-party organic fluorine testing to ensure no fluorinated additives or residues are present. This places Moody Blue among the cleanest contact lenses available today.
2. FDA-Cleared, ISO-Certified Manufacturing
Your lenses are produced in facilities meeting ISO 13485 medical device standards and strict contamination-control processes, ensuring medical-grade purity.
3. Clean Silicone Hydrogel — Zero Shortcuts
Instead of adding PFAS for smoothness, we rely on next-generation Silicone Hydrogel engineering.
This naturally provides High oxygen permeability (Dk/t) and low-friction comfort without chemical coatings.
How to Avoid PFAS in Your Contact Lenses (A Buyer's Guide)
Learning how to avoid PFAS can feel overwhelming because these chemicals are everywhere. However, you have full control over the medical devices you choose.
If you are looking for how to avoid PFAS in your daily eye care routine, follow this 5-step checklist:
-
✅ Check Certification: Does the brand explicitly state "PFAS-free materials"?
-
✅ Look for Testing: Do they disclose results for organic fluorine (ppm)?
-
✅ Prioritize Material: Choose modern Silicone Hydrogel rather than older fluoropolymers.
-
✅ Verify E-E-A-T: Does the brand discuss safety science openly?
-
✅ Demand Transparency: Are manufacturing standards (ISO/FDA) clearly listed?
Moody Blue checks all five boxes.
The Future Is PFAS-Free — And It Starts Here
PFAS awareness is rising. Regulations are changing. Consumers are demanding cleaner materials.
We’re already here. At Moody, we believe your eyes deserve clean chemistry, honest transparency, and medical-grade safety.
Frequently Asked Questions About PFAS in Contact Lenses
-
Do contact lenses contain PFAS?
Some older and popular contact lens brands have been found to contain organic fluorine, a marker of PFAS. These “forever chemicals” are often used to make lenses smoother or more durable. Moody Blue lenses are rigorously tested and confirmed PFAS-Free.
-
Are PFAS harmful to the eyes?
PFAS can accumulate in the body over time. Because the eye is highly absorbent, placing PFAS-containing materials directly on the cornea may contribute to unnecessary exposure. While research is ongoing, major health organizations advise limiting PFAS contact whenever possible.
-
Are silicone hydrogel lenses PFAS-Free?
Not all silicone hydrogel lenses are PFAS-Free. Some manufacturers still use fluorinated additives. Moody Blue uses a clean, advanced silicone hydrogel formula with zero PFAS, verified through organic fluorine testing.
-
How do I choose PFAS-Free contact lenses?
Look for brands with transparent ingredient policies and PFAS-Free certification. Choose lenses with clean material science—such as Moody Blue—rather than products that rely on fluoropolymer coatings.
-
How to avoid PFAS exposure in daily life?
Beyond choosing PFAS-free contact lenses like Moody Blue, you can reduce exposure by filtering your drinking water, avoiding stain-resistant furniture treatments, and replacing non-stick cookware with stainless steel or cast iron.
-
What are the symptoms of toxic contact lenses?
Lenses with poor chemical composition can cause eye irritation, redness, burning, or dryness. Switching to a clean daily disposable often resolves these issues.
