52mm CPL Polarizer Lens Filter for Smartphone Photography Anti Reflective HD Clip On Mobile Enhance Sky Water Scenes Tra
Coating formula unknown. Optical filters seldom use PFAS.
This smartphone lens filter has an undisclosed anti-reflective coating. Most optical coatings skip PFAS, but the brand won't say either way.

What 52mm CPL Polarizer Lens Water Scenes Tra is made of, ingredients and materials
This is a circular optical glass lens with an anti-reflective coating applied to reduce glare and enhance image contrast. The core material (optical glass) is inert and poses no leaching or off-gassing risk under normal use. The coating composition is not disclosed by the brand; most CPL filters use multi-layer dielectric coatings (often magnesium fluoride or similar optical polymers), which are stable and not known to release hazardous substances during handling or exposure to light and heat.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
Unknown / proprietary coating
A coating is recorded with no disclosed chemistry.
Coating degradation and microparticle release
Long-term abrasion or physical damage to the coating could theoretically release microscopic particles. This is a durability issue rather than a primary chemical safety concern but warrants careful handling. Replacement is cheap and easy if coating fails.
What’s reassuring
Anti-reflective coating leaching
No toxicological data on coating composition is available. Dielectric optical coatings are generally chemically stable and not known to leach under smartphone use conditions (room temperature, brief exposure to skin oils and moisture). Risk is theoretical only.
Heavy metals
Optical glass historically sometimes contained lead for refractive properties, but modern optical filters rarely use lead-containing glass due to cost and regulation. No specific lead or cadmium risk has been reported for smartphone accessories. Glass composition is not disclosed, so this assessment is based on industry norms.
Source, FDA ↗Adhesive or mounting material toxicity
The clip-on mount likely uses standard plastic (polycarbonate or ABS) and non-toxic adhesives typical of smartphone accessories. No reports of skin irritation, off-gassing, or chemical release from filter mounts exist. Material is not disclosed but poses negligible risk for brief contact.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand provides no material safety data sheet or coating composition details for this accessory. The company has faced scrutiny on electronics manufacturing transparency but maintains general product safety standards for optical accessories. No recalls or safety complaints specific to CPL filters from the brand are on public record. Lack of proactive material disclosure is a transparency weakness rather than evidence of a hidden hazard.
How it compares in its category
Smartphone lens filters are among the lowest-risk optics accessories because they are passive optical devices with minimal chemical complexity. Most competitors (including generic brands and premium manufacturers like B+W or Hoya) do not disclose anti-reflective coating formulas either, making this product typical rather than distinctive. The main differentiator in this category is optical quality and durability, not chemical safety.
If you buy it
Handle the glass surface carefully to avoid scratches and coating damage, which could reduce optical performance. Store it in a dust-free case or pouch; do not expose to extreme heat or direct flame, as the glass substrate is stable but adhesive bonding of coatings may degrade above 60-70°C. Clean gently with lens-specific cloths and solutions; avoid abrasive materials. No special disposal precautions are required; treat as standard glass waste at end of life.
