Is Trivex thicker than poly?

Lenses created 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. But you can find differences that may make Trivex a preferable option.

• Digital lenses that have been fabricated with a compensated Rx will enhance the patient’s visual acuity and reduce eye strain.
• These lenses provide 100% protection from the sun’s UV rays, and are obtainable in a multitude of lens materials and designs, including bifocal and progressive lenses.
• GlassesUSA has a huge selection of contacts, glasses, & sunglasses.
• Opticians recommend these kind of plastics because of the UV protection and high-impact resistance.

It has ten times more impact resistance when compared to a high-index lens, rendering it ideal for athletes and children. After the lenses have already been made, they need to be installed in the eyeglass frame. They are then “Edged” or cut and formed to fit precisely in to the frame. It could be done at the lens laboratory, or in the optical store.

Polycarbonate Vs Trivex Lenses Compared

These kinds of design can also increase the peripheral view by getting rid of distortion. Those who want to avoid scratches on the eyewear can require an anti-scratch coating on this type of plastic material. The higher the Abbe value, the lower the chromatic aberration and the bigger the likelihood of visual clarity. That means both materials can make the best lenses for several our needs. That said, you may still find some subtle differences between them that I’ll try to highlight. If you want safety glasses, consult an optician who can tell you which frames are safety rated.

Because of their durability to withstand fractures, polycarbonate lenses are employed extensively for rimless and semi-rimless eyeglasses. The lenses are joined with the frame components using drill mountings.

We’ll lay out the facts, put the lenses to the test, and attempt to put the question to rest. While we get plenty of training on these services I find that many of us question when to utilize high-index lenses and just why.

• This means that the product is more common and costs have gone down slightly.
• Our personal, customized services meet all your optical needs – and then some.
• each have many years of experience and do a large number of lenses each week.
• Specific gravity is the weight in grams of 1 cubic centimeter of the material.

Each lab that we use inspects each lens many times during the manufacturing process. When we have the finished product from the lab, we do our own final inspection. We only utilize the highest quality lenses available in the U.S. – Crystal Vision Lenses, and Varilux lenses.
to common problems like being dropped or scratched. Also, they are very resistant to unusual problems, like several chemicals. They can resist acetone, which few plastics can resist, including polycarbonate. Acetone is a common chemical in nail polish removers plus some other solvents which may be around your house. People who enjoy the outdoors or work consistently outdoors can benefit from Trivex. The ultraviolet protection, great visual clarity, and strong material make sure they are a good choice for those with active lifestyles, like hikers or runners.
Although more expansive than traditional glass lenses, polycarbonate lenses offer durability, UV protection, and better clarity of vision. For children’s eyewear, choose a sturdy frame and lightweight polycarbonate or Trivex lenses. Nearly all high index lenses have a factory-applied scratch-resistant coating for added durability.

Developed by PPG Industries in 2001, Trivex lenses are lightweight plus much more impact-resistant than regular plastic or glass lenses. Found that 75% of high prescription patients have a desire for more appealing and discreet eyeglass lenses. High Index lenses offer you the ability to give them the thinnest, lightest lenses they will have ever worn. The Trivex lens designers have incorporated the most desirable attributes into one lens material. It combines good optical quality with the lightest weight material that may meet FDA impact resistance as thin as 1.0mm. Trivex material will be the only two materials that meet up with the ‘high
Polycarbonate may be flexible and impact-resistant, nonetheless it scratches easily. You can choose poly lenses having an anti-scratch coating to combat this disadvantage, but that’s another expense for you to pay. That don’t require a thick lens to refract light effectively.
