Is trivex better than polycarbonate?

It performs better in chemical resistance than a few of its other competitors. Lenses made from Trivex provide 100% UV protection from both UV-A and UV-B radiation. Trivex has been shown to be resistant to household products like bleach, salt water, window glass cleaner, sun tan cream, and nail polish remover. Trivex is also much more resistant to chemicals than polycarbonate. But there are differences that may make Trivex a preferable option. Is made from a thermal casting process, where in fact the material is filled into a cast and permitted to cure over time, several hours, before being removed. Before purchase, you need to research the reputation and reliability of one’s preferred eyewear store online like Consumer Reports or the higher Business Bureau .

• Usually, Blaine Eye Clinic strongly discourages the use of glass lenses.
• Some individuals use window glass cleaner on the glasses, and this can harm other types of plastic.
• It’s important that protective eyewear has lenses crafted from one of these brilliant materials.

Polycarbonate includes a 1.58 index of refraction in comparison to Trivex’s 1.53 measurement. Lens thickness is measured by the index of refraction – the relative measure of how efficiently the lens material can bend and facilitate light.

What’s The Difference Between High Index And Polycarbonate Lenses?

vision with simple polycarbonate lens options. Trivex was originally developed for military use by PPG Industries in 2001. The business then took this ultra-strong, lightweight material and applied it to consumer optical needs. The biggest pro in comparison to polycarbonate is Trivex’s Abbe value.

• So some people choose to pay out of pocket for Trivex lenses.
• This implies you won’t get yourself a possiblity to test or have the material beforehand.
• Trivex is a new lens material originally developed for military applications,Trivex is stronger, clearer, and lighter than polycarbonate.

Their new monomer has material properties much like Trivex and in addition enjoys a higher 45 Abbe value. An added benefit may be the higher index than Trivex, resulting in a slightly thinner lens.

Disadvantages Of Trivex Lenses

Trivex lenses are an excellent choice if safety is an issue or you lead a dynamic lifestyle. If you’re considering purchasing new eyewear and are interested in Trivex, get hold of your eye care specialist for additional information. Rimless frames tend to be more expensive than full-frame glasses. Specific gravity describes the ratio of density of any given material to that of a reference substance. In effect, a lower value means that it is less dense, i.e. more lightweight. The Abbe value is essential since it measures chromatic aberration .

Depending on the amount of chromatic aberration, images viewed through eyewear can happen pretty much distorted. Prescription glasses with lenses made from Trivex have a higher Abbe value of 43 to 45. Children can also benefit from Trivex glasses, since they are more prone to forgetting, dropping, crushing, or damaging their glasses.
