Trivex was invented for the
military as a polymer that is clearer and lighter than
poly. The name Trivex was derived to reflect the
combination of the three distinctive characteristics:
excellent optics, impact resistance and its lightweight
nature. However, Trivex is slightly lower on the
refractive index than
poly with a 1.53 index vs 1.59 index (poly). This
difference in index refers to a slightly thicker anatomy
than poly. However, if processed by an experienced lab,
Trivex can be comparable to poly in thickness and
weight, but with significantly better optics. First introduced
to the public in 2003 this lens medium is an ideal
material for patients that want rimless, safety, and/or
sports eyewear and cannot adapt to poly and/or are
looking for the clearest optics/impact resistance. |
