Best Samsung Galaxy S25/S24/S23 Ultra Lens
Lower concern. Bare glass lens poses minimal PFAS risk.
Smartphone camera lenses are typically uncoated borosilicate glass, an inherently PFAS-free material. Samsung provides no PFAS disclosures; no public lab testing available for this accessory.

The full breakdown
What it's made of and why it matters
Samsung Galaxy S25/S24/S23 Ultra camera lenses are precision optical glass, typically borosilicate or soda-lime formulations optimized for light transmission and scratch resistance. Borosilicate glass (if used) has a lower thermal expansion coefficient, reducing stress from temperature swings during heavy camera use or flash cycles. Glass is chemically inert under normal smartphone operating conditions and does not leach compounds into food, skin, or water; it poses no microplastic risk and does not off-gas volatile organic compounds.
The brand's record and disclosure
Samsung has not published detailed material declarations specific to camera lens composition, which is typical for mobile manufacturers where optical components are proprietary subsystems. The company maintains general sustainability reporting but does not highlight lens-specific safety certifications or material sourcing protocols. No recalls or safety incidents related to Galaxy S23/S24/S25 camera lenses have been documented in public health or consumer databases.
How it compares in its category
Glass optical components are the industry standard for smartphone camera systems and pose minimal hazard compared to plastic lens alternatives (which risk scratching, yellowing, and reduced optical clarity). Premium brands like Apple and Google use comparable borosilicate glass formulations with equivalent inertness. Unlike coated metal camera frames or plastic protective lenses, bare optical glass carries no known risk from lead, cadmium, or degradation-related leaching.
If you buy it
Clean the lens with a microfiber cloth or lens pen to avoid scratches that compromise optics; avoid prolonged direct sunlight focused through the lens, which can degrade internal coatings or sensor components. The lens itself does not require maintenance beyond dust removal. Thermal stress from extreme temperature swings (below freezing or prolonged direct heat exposure) is unlikely to crack borosilicate glass under normal smartphone use but may affect adhesive seals in the lens assembly.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Optical coating degradation
Multi-element optical systems in flagship Samsung phones use anti-reflective coatings (typically magnesium fluoride or similar) that may degrade under prolonged exposure to moisture, salt spray, or direct sunlight. Coating failure affects image quality rather than safety, but degraded coatings can increase internal reflections and lens flare.
Thermal stress (glass fracture)
Borosilicate glass is highly resistant to thermal shock. No public incidents of Galaxy S23/S24/S25 camera lens fracture from temperature extremes have been reported, and normal smartphone operating ranges (0-40 degrees Celsius) pose negligible risk.
Microplastic shedding
Glass is a non-polymeric material and does not shed microplastics under any foreseeable use condition. This hazard is irrelevant to glass optical components.
Heavy metal leaching (lead, cadmium)
Borosilicate and soda-lime glass used in optical applications are formulated to exclude lead and cadmium, and glass is chemically inert. No leaching pathway exists unless the lens is chemically degraded or consumed, neither of which occurs in normal smartphone use.
Adhesive or binding material toxicity
Camera lenses are bonded to metal or plastic frames using epoxy or optical cements that are not fully characterized in public disclosures. These adhesives are sealed inside the camera module and do not contact skin or consumables under normal use, but outgassing is theoretically possible if the phone is damaged or overheated severely.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
