In the research
7 PubMed papers mention it with jewelry, allergy, eyewear or UV; the three most recent:
- Image-Based Identification of Ophthalmic Lens Optical Characteristics: A Benchmark of Local Texture Descriptors for Non-Destructive Optical Inspection · Sensors (Basel, Switzerland), 2026
- Bioinspired Turing-Nanoarchitected Needle for Solid Matrices Analysis: A Universal Platform Enabling Dual-Scale SERS Enhancement · Advanced materials (Deerfield Beach, Fla.), 2025
- Reverse and forward engineering of Drosophila corneal nanocoatings · Nature, 2020
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 lens coatings
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.
