Trivex wiki
WebTrivex I'm getting my first set of progressive lenses, and the optician recommended zeiss premium progressive high index lenses (1.67 index) for the best optics. He said it would cost $550 just for the lens, which sounds expensive to me. He also recommended an anti-reflective coat ($150 for the higher end coat and $80 for the less expensive coat). WebIt may of course simply be because my to eyes have changed and the prescription increased (change of +0.5 sph and -0.5 in cyl) Researching and lurking in this forum I am therefore considering if Trivex would be a better option, but most descriptions seem to refence Trivex superiority compared to simpel Polycarbonate and not MR-8.
