Trivex Vs Polycarbonate Cost

But in most cases polycarbonate will be significantly cheaper and be obtainable in more options. There’s a simple technique to differentiate between your two. Try to edge yourself; if it has strips attached to the edge, it’s polycarbonate.

• Our lenses are all made out of advanced plastics and are obtainable in seven indexes, that may determine how thick or thin your glasses lenses will undoubtedly be.
• Lenses are the best
• However, CR-39 plastic would require a special UV protection coating for outdoor use.
• Often, a full couple of glasses take a fourteen days to come in.
• It has the ultraviolet blocking properties and shatter resistant properties of polycarbonate.
• Trivex is also much more resistant to chemicals than polycarbonate.

High index plastic’s index ranges from 1.67 to 1 1.74, rendering it thinner and more lightweight than Trivex. However, there is no difference in their scratch resistance properties. Both materials have almost similar forms of properties, except there, is one major factor different that is Abbe value. The scale used to measure the clarity of varying lens materials is called Abbe value. Exactly like polycarbonate, Trivex had not been originally developed to be utilized in eyewear. It was developed remember the need for durable military jet windshields and other similar military applications. In the year 2002, PPG industries developed a chemical process with material to be specifically used for eye lenses.

With higher refractive indexes, there are often more chromatic aberrations, meaning visual disturbances of light, which might be interpreted as blur by some. Chromatic aberrations are higher in polycarbonate lenses. The abbe value of polycarbonate is 30, the cheapest of all lens materials rendering it the worst lens for optical clarity and integrity. For those reasons Trivex may be the better choice in a mid-index lens. Like polycarbonate lenses, lenses made of Trivex are thin, lightweight and much more impact-resistant than regular plastic or glass lenses. Trivex lenses, however, are composed of a urethane-based monomer and so are made from a cast molding process much like how regular plastic lenses are made.
contact with high temperatures, such as for example those found within a closed car through the months of July and August, won’t affect the Trivex substrate. Trivex is also very resistant to material deflection due to the higher temperatures encountered during hard coat curing processes. These can reach over 266 degrees and may bring about optical distortions of the finished lens.

Because of this most high index lenses come with an anti-reflective coating as a typical option. Lenses will be the best lenses in the activity, fishing, and active lifestyle eyewear industry. Stay on the surface of the latest news about prescription safety glasses, eyewear, sunglasses, and all the trends in the market. Trivex possesses a minimal index of just one 1.53, much like standard plastic.
For Tyler, optical clarity is extremely important so he’s a big fan of Trivex. But this option may conflict with the lens features you need, the frame you chose, or your prescription. We invite you to get in touch with our expert opticians and find out which lens material is most beneficial for you. We offer free basic 1.5 index lenses on all prescription eyeglasses. We offer opportunities to upgrade and add features during checkout. We make shopping on the internet for the glasses simple, efficient and
So, in this section, we shall demonstrate the differences between these two lens materials. That was all I needed to say about Trivex vs polycarbonate. Both materials are sufficient for providing a fantastic optical experience to the users. Also, remember that at last everything depends on your individual choice and you should pick the lens accordingly. In general, both materials are ideal for eyewear applications. Trivex lenses have less internal stress and could produce sharper central vision than polycarbonate lenses.

Conversely, the thinnest lenses for a higher prescription could be the higher index lenses. That goes on both sides of the lens , and it allows light to pass more freely through the lens. CrystalViewAnti-reflective coating continues on both sides of the lens , and it allows light to pass more freely through the lens. AR No-Glare coating helps it be easier for other folks to start to see the wearer? S eyes, and it makes it easier for the wearer to look out of the lens. Follow this link to read articles about anti-reflective coating. This has outshined all the previous methods instead now new technology has resulted in a variety of options accessible.

• Polycarbonate and Trivex lenses will provide a more comfortable, clearer vision making them the safe and convenient choice.
• For example, the most recent Transitions technology or polarized color option will be a choice for polycarbonate lens material first.
• This article will give you insight into different types of lenses and help you to choose the best lenses to your requirements.
• Eyeglasses are very an easy task to break, especially lenses and frames.

Polycarbonate lenses block nearly the entire UV spectrum, including UVA and UVB. UV radiation is absorbed by the material, which prevents it from passing through. It really is so effective, that even a small layer of the material can effectively absorb Ultra violet rays. This shields the skin and eyes significantly better than any sun lotion could. Anti-scratch or anti-reflective coatings can raise costs as well. Fortunately, because Trivex has inherent UV protection, there is no need to pay for a UV coating. Aspheric and atoric lens designs reduce unwanted magnification and minification within more traditional eyewear.
These kinds of design also increase the peripheral view by removing distortion. The higher the Abbe value, the low the chromatic aberration and the higher the likelihood of visual clarity. In america, the usage of Trivex as glasses material is continuing to grow in popularity.

The expense of polycarbonate and Trivex lenses can vary considerably, but many optical stores charge more for Trivex lenses than polycarbonate lenses. Polycarbonate and Trivex lenses both block 100 percent of the sun’s Ultra violet rays without the need for special UV-blocking lens coatings.
