Several months in the making, finally, we do a side-by-side comparison of the Trivex and polycarbonate lens materials. Most opticians have strong feelings and beliefs about these two very different materials. To test those common beliefs and assumptions, we ran a series of tests to see how they actually performed. You might just be in for a shock! It turns out there is much more to lens performance than material properties alone. Tests include impact resistance, tensile strength, Abbe value, chemical resistance, UV protection, price and availability, and more.

Opticians choose lens materials to best fill their customer eyeglass prescriptions. Optician training provides instruction on lens materials, index of refraction, and other properties. But, how can they be sure how the materials will actually perform in practical situations? It turns out there is much more to material performance than we think and lens coatings play an extremely significant role.
