Which is better polycarbonate or trivex?

Trivex lenses have a higher Abbe value so they can produce both sharper central and peripheral vision with less chromatic aberration than polycarbonate lenses. Basically, your vision will be clearer and contain fewer distortions with Trivex lenses.

Is trivex safe as polycarbonate?

In this area, Trivex wins hands-down. It has a far higher clarity in its central and peripheral vision. Trivex has a higher ‘Abbe’ value than polycarbonate. The Abbe value is a measure of the material’s properties with regard to the dispersion of the colours within the light that passes through the lens.

Why do polycarbonate lenses crack?

Causes of Lens Cracks Cracks in eyeglass lenses typically only occur when the pressure on the exterior is too high. For example, people may tighten the frame around their lenses in an attempt to keep a lens from falling out.

Does polycarbonate block blue light?

A convenient, cost-effective option is polycarbonate photochromic lenses, which are clear lenses that darken automatically in response to sunlight and provide ample protection from blue light at all times.

Is Trivex better than high index?

Trivex is more impact resistant than high index plastic, making it a much better choice for safety glasses or other types of glasses that need to meet certain impact requirements.

Is Trivex scratch resistant?

Materials for Glasses: Trivex Is a New Lens Type These materials are resistant to scratching, easy to clean, and easy to shape to the right prescription strength.

Are polycarbonate lenses good?

Thinner and lighter than plastic, polycarbonate (impact-resistant) lenses are shatter-proof and provide 100% UV protection, making them the optimal choice for kids and active adults. They’re also ideal for strong prescriptions since they do not add thickness when correcting vision, minimizing any distortion.

Does all polycarbonate block UV?

Does polycarbonate block UV radiation? Polycarbonate as a material blocks almost the entire relevant UV spectrum, meaning both UVA and UVB. The material absorbs UV radiation and does not allow it to be transmitted through.

Do polycarbonate lenses need scratch coating?

Today, most eyeglass lenses, including high-index lenses and lenses made of polycarbonate and Trivex, have a built-in scratch-resistant coating. Since scratch-resistant coatings are sometimes optional, make sure your optician knows that you want your eyeglass lenses to include hard coating for extra durability.

Why are polycarbonate lenses bad?

Abbe value measures the dispersion of light for different eyeglass lens materials. Polycarbonate rates lower, meaning they have the potential to cause slight chromatic aberrations (visual distortions) in your peripheral vision.

Are Trivex lenses worth it?

Trivex lenses tend to cost more than polycarbonate or standard plastic lenses. But if you want what many eye care professionals consider to be the best combination of safety, comfort, appearance and optical performance for most eyeglass prescriptions, the Trivex price tag may be an investment worth making.
