Trivex lenses are a type of eyeglass lens material that was developed in the early 2000s as an alternative to polycarbonate lenses. Trivex lenses are made from a proprietary blend of several different materials, including urethane and allyl diglycol carbonate, which are combined using a special casting process to create a high-performance, lightweight lens material.
One of the key benefits of Trivex lenses is their strength and durability. Trivex lenses are highly impact-resistant, making them an excellent choice for people who are engaged in sports or other high-impact activities, or who simply need eyeglasses that can withstand daily wear and tear. In fact, Trivex lenses are up to 10 times more impact-resistant than standard plastic lenses, and are also highly resistant to scratches and other forms of damage.
Another advantage of Trivex lenses is their optical clarity. Trivex lenses are highly transparent and free from the distortion and aberrations that can sometimes occur with other types of lens material. This can be especially important for people who need highly accurate and precise vision correction, such as those with high prescriptions or certain types of eye conditions.
Trivex lenses are also extremely lightweight, making them a comfortable choice for extended wear. They are approximately 10% lighter than polycarbonate lenses and up to 20% lighter than standard plastic lenses, which can be a significant difference for people who wear their glasses for long periods of time.
Lastly, Trivex lenses hold the closest Abbe value to the human eye, which is 42-45. This is an important test of optical lens materials because the Abbe value measures the degree to which light is distributed when passing through a lens. If the Abbe value is too low, such as polycarbonate with an Abbe value of 30, it results in poor visual quality and a noticeable distortion in the lens. Whereas if the Abbe value is too high, such as glass with an Abbe value of 58, the human eye won’t notice a difference. Although a higher Abbe value might seem attractive to the wearer, the human eye can only comprehend an Abbe value up to 45. Lens materials such as Trivex make for the most comfortable and crisp viewing experience because they match the Abbe value of the human eye.
Overall, Trivex lenses offer a number of benefits that make them an excellent choice for a wide range of eyeglasses wearers. They are highly impact-resistant, scratch resistant, and optically clear, while also being lightweight and comfortable to wear. If you’re in the market for new eyeglasses, it’s worth considering Trivex lenses as a durable and high-performance option that can provide excellent vision correction and protection for your eyes.
