1.53 Trivex Impact Resistant

However, to guard your investment in your eyewear, scratch-resistant coating is highly recommended for several eyeglass lenses. The only exception is glass lenses, which are naturally hard and scratch-resistant.

• However, manufacturers tend to add blue-light blocking polymer in the lens material in order to make it appropriate for blocking blue light and combat the consequences of digital eye strain.
• Which makes eyeglasses ade from trivex very comfortable also to your relief, it is unlikely that they can slide down the bridge of one’s nose.
• How can Zenni Optical afford to balance quality and price together with they do?
• Higher prescriptions require high index lenses to keep them thin and light.

High index lenses can be up to 50% thinner than regular glass or plastic lenses, and they’re usually much lighter, too. The 1.57 mid index lenses are meant for people who have moderately strong prescriptions, and they are thinner and lighter than standard lenses. The lens is really a polycarbonate composite made from polycarbonate, other polymers, and resins that keep it thinner and lighter than the standard 1.50 lens. High index plastic is thinner and more lightweight, and will often have more options with regards to lens colors and sizes. Trivex is slightly more optically clear and impact resistant than high index. Trivex lenses are slightly lighter, have an increased tensile strength, and could produce sharper central vision and peripheral vision because of their higher Abbe value and lower internal stress. However, Trivex is slightly thicker, less widely available, and usually costs more than polycarbonate.

Proper Frames For Polycarbonate And Trivex Lenses

This is just one less worry that you’ll need to have if you choose these lenses over other styles of lenses. What’s the difference between 1.50 standard vs. 1.57 mid index lenses?
That’s because thinness reduces lens volume and creates the final weight of the lens. However, the true lens weight is a function of volume and the material’s specific gravity. In this case, Trivex material was engineered to function as lightest material (1.11g/cm3). In the same Rxs, lenses with Trivex material are always thinner and lighter than CR-39 monomer due to its index, extreme impact resistance and specific gravity. Mid-index lenses, such as for example 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39. It is lighter and much more scratch resistant and contains high-impact resistance like Polycarbonate. Trivex lenses, however, are comprised of a urethane-based monomer and are created from a cast molding process similar to how regular plastic lenses are created.

• In fact, it is a large choice and one which will significantly impact the protection and clarity of your glasses.
• Alongside impact resistance, these lenses provide 100 percent protection from ultraviolet rays to help you be confident your eyes are increasingly being protected on bright, sunny days.
• This particular characteristic is effective with rimless frames or drill mount eyewear.
• The scale used to gauge the clarity of varying lens materials is named Abbe value.
• High index lenses could be up to 50% thinner than regular glass or plastic lenses, and they’re usually much lighter, too.
• PPG named the material Trivex because of its three main performance properties.

These lenses also provide 100% protection from the sun’s Ultra violet rays, and are available in a wide variety of lens materials and designs, including bifocal and progressive lenses. Polycarbonate lenses have a refractive index of just one 1.59, making them 20% to 25% thinner than regular plastic lenses. They are also up to 30% lighter than regular plastic lenses, making them a good choice for anyone who is sensitive to the weight of eyeglasses on their nose. But when it involves eyeglass lenses, so long as have to compromise. So that you can experience superior eye protection, sharp vision and lightweight comfort — all in exactly the same lenses. Though these lenses are especially beneficial when you have a strong eyeglasses prescription, they can create a noticeable difference in the looks of virtually any couple of glasses.
Actually, I believe trivex has better optics than high index. Though it isn’t guaranteed you’ll even spot the difference. Trivex is not as thin as high index nonetheless it is less dense therefore it ought to be less heavy. It has better impact resistance and naturally blocks UV . Understandably you want to buy the best lenses for the sports glasses in probably the most convenient way possible and and never have to spend a fortune. The higher the quantity, the thinner the lens, as more refraction means less lens material is required to create clear vision. Polycarbonate includes a 1.58 index of refraction compared to Trivex’s 1.53 measurement.

Factors That Affect Lens Thickness

Choosing a small lens size frame is the biggest determinant of lens thickness and weight! Smaller frames also decrease the amount of lens distortions/aberrations. As a result of density of the high index plastic-type material it isn’t usually the lightest material though it is thinner. Trivex along with polycarbonate is great for rimless frames and the ones frames requiring drill mount screws through the lenses. Check out A Sight For Sport Eyes’ leading range of sports glasses with Trivex and Polycarbonate lens possibilities. Likewise, if you’re out in sunlight all day long, the UV protection offered by both lenses ensures all the harmful sunrays are blocked out, as standard.

Finally, Trivex can undergo many surface treatments, including anti-reflective, hard coatings, and tinting.

It performs better in chemical resistance than a few of its other competitors. Lastly, Trivex has a lower specific gravity (1.11) to that of polycarbonate (1.66).
