• Unlike polycarbonate which can change shape under pressure, Trivex is effective for drill mount/rimless frames.
• This results in greater wearing comfort and ease and fewer problems of heavy eyewear sliding off your nose.
• Since poly lenses happen to be injection-molded, aspheric models were easier to manufacture.
• In these cases, normal bifocal lensess or trifocal lenses can be a better choice.

This mix of impact resistaance, lightweight ease, and UV protection also makes polycarbonate and Trivex lenses great options for children’s glasses and safeness glasses. For years, polycarbonate lenses have already been the industry standard for safety spectacles and children’s eyewear.
