In the research
385 PubMed papers mention it with jewelry, allergy, eyewear or UV; the three most recent:
- Palladium-103 brachytherapy with continuous periodic intravitreal Anti-VEGF bevacizumab for ciliary body medulloepithelioma · American journal of ophthalmology case reports, 2026
- Efficient Green Light-Induced Photoclick Reactions Enabled by Triplet-Triplet Annihilation Photon Upconversion · Angewandte Chemie (International ed. in English), 2026
- Plasmon-enhanced reductive defluorination of PFAS in water under ambient conditions · Nature water, 2026
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on one fabric or one filter says little about the piece in your hand.
Other metals
Clasp & Lens describes materials from the public record and does not appraise, grade or test pieces; what a listing states is the supplier's statement. If a piece causes a rash, take it off; a reaction that spreads or blisters is a doctor's question, and sunglasses are no substitute for impact-rated eye protection where that is required.
