Polycarbonate and Trivex: when impact matters

Start with the activity

Impact resistance describes how a material responds to a blow; a protective eyewear rating applies to an assembled product tested for particular conditions. The frame, lens retention and coverage matter alongside the material. Polycarbonate and Trivex are materials often discussed when impact performance is important, but neither name alone certifies an ordinary pair as suitable for every sport or workplace hazard.

ABDO identifies polycarbonate and Trivex as options when greater impact resistance is needed. That makes them worth discussing for relevant sports or safety applications. A material name alone does not establish that an ordinary fashion frame is suitable protective eyewear.

Compare the complete specification

Ask for the available prescription range, finished weight, coating and frame compatibility for each option. Our suggested comparison uses the same frame and prescription for both quotes. Otherwise a difference in frame size can be mistaken for a difference caused entirely by material.

Include what you noticed before

Bring your previous glasses if they felt heavy, developed damage or were uncomfortable at the edges of your view. Describe the actual difficulty instead of requesting the highest index by default. The dispenser can then discuss which compromises matter in your case.

Ask about the frame as well

For a sport, tell the dispenser about helmets, contact with other players and any organiser’s eyewear requirements. Ask which complete product is appropriate. This guide does not certify equipment or replace the product’s own instructions and local requirements.

A worked example

When comparing two pairs for a ball sport, first ask which complete product meets the relevant sport requirements in your location. Only then compare weight, prescription availability, coatings and fit. A thin high-index dress lens and a rated sports protector answer different questions. Avoid choosing between them as if the only difference were appearance.
