We love talking about frames, colors, styles, and aesthetics but don’t overlook the value of what pentax glasses products like the pentax zt100 and pentax zt200 hold. Yes, it is all about lenses! The fight is between two materials, Trivex and polycarbonate. Both of these lens materials have advantages and disadvantages, so let’s take a closer look to see which is ideal for you.
We can’t compare lens materials unless we talk about UV protection. In terms of UV protection, both lens materials are fairly equal. Polycarbonate and Trivex lenses, in fact, inherently filter UV rays from entering the eyes. This tough plastic is a popular choice for people who have a somewhat high prescription because it can withstand the higher prescription because of thick and heavy.
What Is Polycarbonate?
Polycarbonate has an interesting backstory. While the material was found in the final years of the 1800s, it underwent further processing in the 1960s for use in astronaut visors and helmets. Because of its exceptional strength and endurance, it was employed for eyewear lenses commercially in the late 1970s. Polycarbonate is widely used for Pentax zt100 safety frames and children’s eyeglasses due to its durability and impact resistance.

What Is Trivex?
Trivex is a newcomer to the optical field, and it was originally designed for the military. This material was introduced into the industrial optical market due to three main characteristics: it is incredibly robust and durable, lightweight, and enables fantasy optical ability.
So, what exactly is it made of? It’s a urethane-based pre-polymer, a lightweight, and low-density plastic. Trivex zt200 safety frames have a slightly higher Abbe value, indicating greater optical clarity than polycarbonate material. A low Abbe value indicates that the lenses will have higher chromatic aberration, resulting in a fuzzy or colored edge. However, chromatic aberration is usually only noticeable when gazing from the very edges of your spectacles, rather than straight as is usual.
Difference between Polycarbonate and Trivex Lenses
Trivex and Polycarbonate are very similar, but there are certain distinctions to be aware of.
Dimensions and Weight
The thickness and weight of the two materials are significant disparities. Polycarbonate lenses are thinner than Trivex lenses due to their higher index. The higher the index, the better they are at sustaining a higher prescription. Trivex is really lighter because it is composed of lighter material.
Impact Resistance
Impact resistance is vital, especially for persons who are very active or in sports, and need to maintain their 3m zt100 safety glasses on when running about a field or a busy workplace.
The good news is that Trivex and Polycarbonate are both extremely impact resistant. Both are tough, long-lasting, and scratch-resistant. Both are far more durable than normal CR39 plastic lenses.
UV Protection
We can’t compare lens materials unless we talk about UV protection. In terms of UV protection, both lens materials are fairly equal. Polycarbonate and Trivex lenses, in fact, inherently filter UV rays from entering the eyes. This tough plastic is a popular choice for people who have a somewhat high prescription because it can withstand the higher prescription because of thick and heavy.
Lens Index
The lens index can refract light. The greater the index, the lens can refract light better and the thinner it is. A strong prescription used to be associated with a set of thick lenses which rested heavily on the face. You can now have super strong 3m safety glasses zt200 while still enjoying thin lenses with a high refractive index and better technology.
Trivex has a significantly lower index and is hence more suited for milder prescriptions than polycarbonate. For stronger prescriptions, polycarbonate lenses are a better option.
Optical Clarity
The primary objective of lenses is to improve vision. Thus, the Abbe value increases the optical clarity. Trivex has an Abbe value of 43-45, while polycarbonate has 30. It means that Trivex is more optically clear than polycarbonate. Yet, polycarbonate lenses still provide excellent performance, especially if your prescription is weak.
Which Option Is Better For Your Pair Of Pentax Safety Glasses?
Whatever you choose, you’re getting a pretty clever lens material, particularly if you buy pentax prescription safety glasses at Safety Eyeglasses SEG. However, depending on your demands, some elements may tip the scales in any direction. If your life is hectic, lively, and a little rowdy, polycarbonate is an excellent choice. They are stronger, have superb UV protection, and are slim enough to fit neatly into any frame, including fragile ones. If you have fewer prescriptions or use your glasses on occasion, Trivex is a good option.
The good news is that lenses made of polycarbonate are suitable for the majority of frames. They look great in full frames but are also a wonderful choice for semi-rimless frames. For rimless frames, a Trivex lens may be preferable for the added tensile strength.
