Microplastics from Contact Lenses: Environmental Impact and Safer Vision Alternatives
For millions of people, contact lenses are a convenient alternative to glasses, offering freedom, flexibility, and clear vision without frames. However, what many contact lens wearers don’t realize is that these lenses are made from plastic-based materials that can contribute to a growing environmental concern: microplastic pollution.
As awareness of microplastics and their impact on the environment continues to increase, researchers are taking a closer look at everyday products that may contribute to the problem—including contact lenses. Emerging research suggests that discarded lenses and lens-related waste may play a small but noteworthy role in the accumulation of microplastics in our waterways and ecosystems. The findings may surprise you.
What Are Microplastics?
Microplastics are tiny plastic particles measuring less than five millimeters in size. Today, microplastics exist in oceans, rivers, soil, food, and the air we breathe.
According to the United Nations Environment Programme, the world produces more than 430 million tons of plastic annually, with a significant portion eventually becoming microplastic waste. Scientists have detected microplastics in marine life, drinking water, and even human blood.
While contact lenses represent only a small piece of the overall problem, their contribution is often overlooked.
The Hidden Environmental Impact of Contact Lenses
Most soft contact lenses are made from plastic-based materials such as silicone hydrogels. These materials are designed for comfort and oxygen permeability but are not biodegradable.
Research suggests that between 15% and 20% of contact lens wearers dispose of their lenses by flushing them down sinks or toilets. Once in wastewater systems, lenses can break down into smaller plastic particles that may eventually enter waterways and ecosystems.
A study presented by researchers at Arizona State University estimated that in the United States alone, approximately 6 to 10 metric tons of contact lens material enter wastewater systems each year due to improper disposal.
More Than Just the Lenses
The environmental impact extends beyond the lenses themselves.
For daily disposable lens wearers, this can amount to more than 700 individual pieces of packaging annually.
When multiplied by the estimated 45 million contact lens wearers in the United States, the amount of plastic waste generated becomes substantial.
The Ongoing Cost of Contact Lens Wear
Beyond environmental concerns, contact lenses also represent a long-term financial commitment.
The average contact lens wearer may spend:
💠 $250–$800+ per year on lenses
💠 Additional costs for cleaning solutions and accessories
💠 Periodic contact lens exams and prescription updates
Over a decade, those expenses can add up to several thousand dollars.
LASIK and PRK: A More Sustainable Vision Correction Solution
For patients who are good candidates, LASIK and PRK at Dishler Laser Institute offer a long-term vision correction solution that can also help reduce environmental waste and the ongoing costs associated with contact lenses.
Unlike contact lenses, LASIK and PRK are one-time, advanced refractive procedures that permanently reshape the cornea to correct common vision issues such as:
· Nearsightedness
· Farsightedness
· Astigmatism
After treatment, many patients enjoy clear, reliable vision without the daily need for disposable lenses, plastic packaging, or cleaning and storage solutions—supporting both convenience and a reduced environmental footprint.
Benefits of LASIK and PRK Include:
☑️ Reduced dependence on glasses and contact lenses
☑️ Elimination of recurring lens-related plastic waste
☑️ Potential long-term cost savings
☑️ Freedom from daily lens maintenance
☑️ Convenience for active lifestyles, travel, and outdoor activities
LASIK vs. PRK: Which Is Right for You?
Both procedures use advanced laser technology to correct vision, but they differ slightly in technique.
A comprehensive consultation with an experienced refractive surgeon can determine which option is best for your eyes and lifestyle.
A Clearer Future for Your Vision—and the Planet
Contact lenses remain a safe and effective vision correction option for many people. However, their environmental footprint is becoming increasingly difficult to ignore.
Choosing LASIK or PRK isn’t just about seeing clearly without glasses or contacts. For many patients, it’s also an opportunity to reduce daily waste, simplify their routine, and make a long-term investment in their vision.
If you’re tired of the ongoing costs, maintenance, and environmental impact of contact lenses, now may be the perfect time to explore your vision correction options.
