Trivex and Polycarbonate: How to choose the ideal lens for your eyewear

You have to choose between Trivex and Polycarbonate lenses. This is important for your vision and comfort with your glasses. Polycarbonate is shock resistant, more durable, and costs less. Trivex offers you a clearer vision, weighs less, being ideal if you are looking for a lot of sharpness and comfort for your eyes.

About Trivex and Polycarbonate: The basics you need to know

When it comes to eyewear, the lens material is as important as your prescription. There are two materials widely used to make lenses: Polycarbonate and Trivex. Both of them changed a lot how glasses are made, now they are lighter and more resistant. Before the old lenses broke easily, they weighed a lot. Polycarbonate appeared in the 80's, people accepted it quickly because it was very hard and shock resistant, so they use it a lot for safety and sport glasses. Trivex appeared around 2000, it was looking to be clearer and lighter but it also held up well. Knowing the difference helps you to make the right choice, so that your eyes are protected and comfortable according to what you do in your daily life.

What is Polycarbonate? We tell you.

Polycarbonate is a very strong plastic. It was first created for things in space, such as astronauts' helmets or spacecraft windows, just imagine. It withstands shocks very well, that's why they started using it for glasses in the 80s. These lenses are very light and thin, plus they protect you 100% from the sun, from UV rays. They are a great option if you want something that lasts, is safe and economical.

What about Trivex? Check it out.

Trivex is a newer lens material. It was introduced in 2001. It was designed to be lightweight, strong and, most importantly, to provide much clearer vision. They make it with something called urethane monomer, that's part of the process. It's made in a special way, so the lenses have less distortion on the inside. It withstands impact about the same as Polycarbonate, but it has a higher Abbe number. This means you see sharper and with less odd colors. It is a premium choice if you are looking for high quality vision.

Trivex and Polycarbonate: Numbers and Comparison

This part is important. Here we explain the differences between Trivex andPolycarbonate. We are going to analyze their technical characteristics and their practical application. We want you to choose the best glasses for you. We will talk about how you see with them, how long they last and how much they cost. Aesthetics is also an important factor.

How to See Clear (The Abbe Number)

Seeing well and clearly is key to avoiding visual distortions. Truth be told, no one likes to see blurry. The Abbe Number tells us this. It measures how well the lens material separates light. A high Abbe number is good. It means the light is not scattered too much and you won't see those chromatic aberrations.

Trivex lenses have an Abbe Number of 43 to 45 or so. This makes you see very clear, and almost no chromatic distortion. You won't get halos. The image looks super sharp and the colors are very accurate. Even if you look at the edge of the lens, or if you have high prescriptions. People who want the best for their eyes often opt for Trivex.

But Polycarbonate lenses have a lower Abbe Number, like 30 to 32. They are suitable for most people. This feature can cause you to see a small rainbow or color halo (chromatic aberration) around objects. This sometimes happens if you are very sensitive or if your prescription is high. For most things you do, the clarity of Polycarbonate is fine. People who want to protect their children choose Polycarbonate. If extreme clarity is your priority, Trivex is the superior choice.

Shock and Impact Resistance and Durability

Both Trivex and Polycarbonate withstand impact much better than the old fashioned plastic or glass lenses. That's why they are excellent for safety glasses, for people who do sports or for children. They also meet important standards such as ANSI Z87.1, which offers peace of mind and safety.

Polycarbonate is extremely tough, up to ten times stronger than regular plastic. It withstands shocks very well, it does not break if something hits it hard, so it is good for dangerous places or if you do a lot of sports, it is widely used.

Trivex is also tough, it holds a little less than Polycarbonate in extreme impacts, but it is still very tough. It meets and exceeds safety standards, offers excellent protection against breakage or pitting, and is suitable for most users, even people with a very active lifestyle.

For day-to-day use, the difference in hardness is barely noticeable, both protect you a lot from numerous accidental impacts. Your eyes are safe, they do not break into dangerous fragments, ensuring the safety of your eyes.

Weight and Comfort

The weight of the lenses matters for you to be comfortable with the glasses, especially if you wear them a lot or if you are sensitive to weight. Polycarbonate lenses are lightweight, weighing less than standard plastic lenses and considerably less than glass lenses.

But Trivex lenses are even lighter, the lightest material available for everyday lenses, they are extremely lightweight. This extra lightness translates into superior comfort, ideal for large frames, high prescriptions, or if you want to feel like you're not wearing anything at all. They do not put pressure on the nose or ears, which enhances the wearing experience.

UV protection

Protecting yourself from the sun is crucial for your eyes, in the long run, so you avoid problems like cataracts or macular degeneration or retinal damage. Luckily, Trivex and Polycarbonate give you 100% UV protection, blocking all those harmful ultraviolet rays, UVA and UVB. They don't need special coatings for this, like other materials, they both ensure that your eyes will be totally safe from the sun, they are an excellent choice if eye health is your priority.

Lens Thickness and Aesthetics

Lens thickness depends on the refractive index of the material, a higher index means thinner lenses, it's as simple as that.

Polycarbonate has a refractive index of 1.59. That's why we call it a"high index" material, it makes the lenses much thinner and better looking than regular plastic lenses, especially if you have high prescriptions. It makes quite a difference.

Trivex has a refractive index of 1.53, a little less than Polycarbonate. It could be that the lenses come out slightly thicker for the same prescription, but the difference is minimal in most cases. Trivex is very light and that compensates for its possible thicker thickness, looks good and is very comfortable. For extremely high prescriptions, Polycarbonate may give you a slightly thinner lens, but Trivex is lighter and gives you very clear vision.

Cost and Accessibility

Money matters a lot when people choose their lenses. Polycarbonate lenses are usually the more affordable of the two options. Their manufacturing process is more standardized and their popularity is greater, so their price is easier to afford. They offer a lot of strength and protect you from the sun at a competitive price, which is why they are so popular, making them excellent value for money.

Trivex lenses are a more modern material, their manufacturing process is more complex and they offer greater visual benefits, which is why they usually cost slightly more than Polycarbonate lenses. That higher price is because they have invested in their development and because of the high visual quality and extreme lightness. That additional investment in Trivex can be justified if you are looking for the best vision and comfort. The final price will always depend on your prescription, the extras you choose and the optician, each one has its own prices.

Compatibility with Additional Treatments

Trivex and Polycarbonate are compatible with many additional treatments. You can add anti-reflective coatings, anti-scratch hard coatings, blue light filters, hydrophobic and oleophobic treatments. There is no big difference in how they wear or how well they perform from one material to another, allowing for complete customization of your lenses.
