Is polycarbonate more scratch resistant than Trivex?
eye gear and sports goggles are made of polycarbonate lenses, even when no vision prescription is needed. Furthermore, polycarbonate boasts built-in protection from the sun’s Ultra violet rays, making this an ideal lens material for time spent outdoors. Since that time, polycarbonate lenses have become the typical for safety glasses, sports goggles and children’s eyewear. Polycarbonate lenses will vary from glass or plastic lenses because they’re thinner, lighter, and 10 times more impact-resistant. They provide extra safety for your eyes without sacrificing comfort or fit. Because of the several benefits to polycarbonate lenses, they generally double in price from glass or plastic lenses. A choice with high index lenses can be an “aspheric” design, that may donate to a thinner lens appearance and profile.
This assists you determine if you might reap the benefits of Trivex or if you can get good vision with simple polycarbonate lens options. Trivex is resistant to many chemicals in other common household items, like window glass cleaner
We suggest putting the material during your own tests and deciding on your own. Additionally, Trivex’s light transmittance is 91.4 percent, directly affecting the clarity, brightness, and crispness of your vision when wearing this lens material.
The higher the abbe value, the less dispersion and distortion. Trivex comes with an abbe value of 43–45, while standard polycarbonate comes with an abbe value of 30. Stay on top of the latest news about prescription safety glasses, eyewear, sunglasses, and all the trends in the industry.
These materials are resistant to scratching, easy to clean, and an easy task to shape to the right prescription strength. Trivex lenses have a higher Abbe value than polycarbonate since it is made up of a urethane-based monomer, which refracts less light. When lenses are made of materials with less Abbe value, a particular deviation depending is expected. The wearer may notice fuzzy rainbow halos around lights. Trivex lenses will certainly offer better clarity and visual experience than polycarbonate lenses, thanks to their high ABBE value.
To measure the clarity of various lens materials, we use something called the Abbe value. Discuss how Trivex, a new lens material which won’t chip, fracture, crack or break, will combine lightweight and superior optical quality for a tangible visual improvement. When you attend order, consider specifying Trivex instead of other options for prescriptions in the number between -3.00D and +3.00D. Impact Resistance—no ophthalmic-grade lens material is more impact resistant than Trivex.
- Bifocal lenses permit the wearer to look through two areas of the lens.
- In the
- Polycarbonate lenses may be thinner, lighter, and much more durable than plastic-type material, but that’s definitely not true in comparison with rival technology like Trivex lenses.
- Hoya designed its Trivex-based solutions to be super-light and sturdy for active everyday living.
- Liingo Eyewear is another great substitute for buy glasses online.
Like polycarbonate, Trivex also offers inherent UV protection. However, unlike polycarbonate, Trivex comes with an Abbe value of 45, rendering it optically superior on paper. The tensile strength of Trivex helps it be highly resistant to cracking around drill holes. Actually, Younger Optics guarantees its Trivex products for life, against stress fractures and drill mount cracking. They are produced using a slower, cast molding process similar to how regular plastic lenses are created.
- Trivex has a significantly higher ABBE value than polycarbonate, which measures the chromatic aberration, aka clarity, of a specific lens material.
- While Trivex has a slightly lower refractive index (1.53 compared to 1.58), it’s specific gravity,
- Fortunately, recent technologies have developed a new kind of lens, called the no-line, or progressive, lens.
- Trivex lenses come in handy for rimless glasses where small holes are drilled to attach the glasses to the frame.
- A segment, usually with a line in the bottom of the lens.
For lenses minus the coating, much of the light reflects off the lenses and may produce glare or reduce clarity of vision. This coating will make it easier for you yourself to see and easier for others to see you.
The liquid polycarbonate is then rapidly injected into lens molds, compressed under ruthless, and cooled to create a finished lens product in a matter of minutes. The most popular lens materials today are Plastic (or CR-39), Polycarbonate, High Index, and Trivex®. Let’s talk about the huge benefits and drawback to each and where each is particularly useful. Most other plastic lenses are produced from a cast molding process, where a liquid plastic-type material is baked for long periods in lens forms, solidifying the liquid plastic to make a lens. The price and quality of polycarbonate lenses will change depending on your prescription and the seller, so it’s worth shopping around.
