Is Trivex scratch resistant?
Pros of Trivex Lenses Lenses made from Trivex are extremely resistant to common problems like being dropped or scratched. They are also very resistant to unusual problems, like several chemicals. They can resist acetone, which few plastics can resist, including polycarbonate.
What is the most scratch resistant lens material?
Glass. Glass offers superior optics and is the most scratch-resistant material available.
Which is better polycarbonate or Trivex?
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.
Is polycarbonate more scratch resistant?
Polycarbonate is your ideal composite material for things like bulletproof glass and riot shields. Its high impact strength and high light transmission make it ideal for greenhouses. Acrylic, like polycarbonate, has very high light transmission, but is also extremely scratch resistant.
Does Trivex scratch easier than polycarbonate?
Polycarbonate lenses are more scratch resistant than plastic, but less than trivex lenses.
Is Trivex more scratch resistant than CR-39?
The lower numbers are classified as mid-index lenses. Mid-index lenses, such as 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39. Trivex is an improvement over Polycarbonate. It is lighter and more scratch resistant and has high-impact resistance like Polycarbonate.
Which is more scratch-resistant acrylic or polycarbonate?
Polycarbonate offers much more resilience than acrylic, making it ideal for highly demanding applications like bullet-resistant windows. Acrylic has a high gloss finish and is more transparent, making it ideal for display cases. Acrylic is also easier to crack, while polycarbonate is easier to scratch.
How scratch-resistant is acrylic?
Cast and extruded acrylic glass is among the thermoplastics with the highest surface hardness, as well as offering excellent scratch resistance. This is confirmed by the pencil hardness test, among others.
Is Trivex as impact resistant as polycarbonate?
Summary. Trivex has the impact resistance and inherent UV protection of polycarbonate. With a lower index of refraction, Trivex may be slightly thicker than polycarbonate, but is lighter, and can be surfaced to the same 1mm center thickness.
Are acrylic lenses scratch-resistant?
But even with the addition of this scratch-resistant coating, plastic lenses are still one of the lens materials that easily gets scratched.
Do polycarbonate lenses scratch easily?
Scratch resistance: A scratch on your lens will affect its clarity and your frame’s overall appearance. Glass and polycarbonate can both become scratched, but polycarbonate is less scratch-resistant, making anti-scratch coatings popular among glasses wearers.
Is acrylic sheet scratch resistant?
Acrylic is a great material, but it has one flaw, which is that it can scratch pretty easily.

Do polycarbonate lenses have scratch coating?
Many plastic lenses nowadays, including polycarbonate, high-index and trivex lenses contain a built-in scratch-resistant coating on the back and front of the lens surface.
Are there scratch-resistant glasses?
There’s no such thing as scratch “proof” lenses. (Even glass lenses can be scratched!) Scratches, while not likely to affect your lens performance, are an annoyance that can interfere with clear vision.
Can scratches be removed from polycarbonate?
If your scratched plastic is clear it is likely to be either acrylic or polycarbonate, which are the two most popular clear plastics. Scratches can be removed more successfully from acrylic than polycarbonate. Once polycarbonate is scratched it is not really possible to remove scratches.
