Trivex lens
On the label: Trivex · Lens material
What it is
A lighter, clearer impact-resistant plastic than polycarbonate; blocks UV, costs more, used in rimless and safety frames.
Lens materials: What a lens is made of decides its weight, clarity, impact resistance and how it takes a coating; UV blocking is a property of the material and its additives, not the tint.
Wikidata: Substance used for optical lenses. Q16617773 →
In the research
2 PubMed papers mention it with jewelry, allergy, eyewear or UV; the three most recent:
- Polymeric Materials for Ophthalmic Lenses: A Systematic Review on Structure, Properties, Manufacturing and Sustainability · Molecules (Basel, Switzerland), 2026
- A Monte Carlo simulation study on the evaluation of radiation protection properties of spectacle lens materials · European physical journal plus, 2023
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 materials
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.
