What is the difference between polycarbonate and Trivex lenses?

Additionally, lightweight lenses tend to be more comfortable and stop the glasses from sliding down your nose or falling off that person. While trivex is comparable to polycarbonate, it includes a few key differences. Trivex was initially created for military used in helicopter and fighter aircraft windows. The material’s chemistry was tailored for use in optical lenses in 2002, making trivex lenses one of the durable and desirable lenses available to buy. Polycarbonate lenses are made from a thin, lightweight plastic seen as a impact resistance and UV protection. To find out more on eyeglass lenses, visit All About Vision®.

• frames are best for you.
• However, there is no difference within their scratch resistance properties.
• Trivex’s density is 16% lighter than common plastic lenses and 8% lighter than Polycarbonate.
• The material was presented with the name “Trivex” because of its three main properties which are good optics, lightweight, and strength.
• However, lens coatings cost money, and the expense of multiple coatings quickly accumulates.

You can use this information to decide which eyeglasses lens material type is right for you personally. Both Polycarbonate and Trivex lenses have equally great ratings in these areas. Regarding impact resistance, you can feel confident that both these glasses will survive being dropped and collisions because of shatter- and scratch-resistant materials. Learn how to pick the strongest lens materials for the sports glasses with this particular expert A Sight for Sport Eyes guide.
The only exception is glass lenses, which are naturally hard and scratch-resistant. Although Polycarbonate lenses are thinner, Trivex’s lenses in sports glasses are significantly lighter in weight. Actually, Trivex lenses will be the lightest lens material available, even compared to regular eyeglasses lenses. Trivex’s density is 16% lighter than common plastic lenses and 8% lighter than Polycarbonate.
If your eyeglass prescription changes, ask your eye health care provider about updating your glasses. You might be in a position to keep carefully the frames you have or pick new ones, depending on what changes to the lenses are necessary. This article reviews the various lens material choices for glasses.
Polycarbonate lenses are injection molded while Trivex lenses are cast molded. Injection molding is really a faster process than cast molding as the cast molding process will take longer and create
TrivexHaving a lightweight lens is essential for a patient’s comfort. Trivex lenses certainly are a breakthrough in lightweight eyeglass lenses. They have the lightest specific gravity of any lightweight material useful for eyeglass lenses available. Conventional glass or plastic lenses reflect about 8% of incident light, so only 92% of available light enters the eye for vision.

Due to density of the high index plastic material it isn’t usually the lightest material though it is thinner. Abbe value is a way of measuring the lens material’s dispersion of light. A lens with a low Abbe value causes an increased dispersion and leads to unwanted chromatic aberration. Chromatic aberration is really a distortion of the image as a result of inability of the lens to target all colors onto exactly the same focal point. This leads to the perception of undesirable color fringes when viewing objects for most people. Whenever choosing your lenses, you also have to consider what frames they’ll be inserted in. To keep your eyes safe, you need to invest in high-quality safety frames explicitly created for your sport or industry.
These are conventional plastic-type material lenses with a refractive index of 1 1.498 which have been trusted since their introduction in 1947. One of the primary advantages of this lens is its affordability. It should be noted however, a scratch resistance coat, as well as a UV coating could be applied to the lens assisting to reduce some of these deficiencies. Trivex lenses have a higher abbe value of 45 while polycarbonate lenses have an Abbe value of 30. The Abbe may be the way of measuring how well an optical material transmits light at different wavelengths and grades color accuracy.

Thinner, lighter lenses manufactured from high index materials reflect around 50% more light than regular glass or plastic lenses (up to 12% of available light). Though aspheric lenses offer advantages of all prescriptions, they’re particularly beneficial in case you are farsighted. And since they have a slim profile, aspheric lenses have less lens mass, making them much lighter. Aspheric lenses also provide superior peripheral vision compared to conventional lenses.
