Do Trivex lenses scratch easily?

For both of these reasons a lot of people have chosen to change to the lighter and safer materials. For example, plastic lenses tend to be more impact resistant than glass lenses, but they can become scratched more easily should they don’t have a protective coating. All eyeglass lenses reflect some light, reducing how much light that enters the attention to form visual images.

• These lenses automatically darken in sunlight, and get rid of indoors.
• However, lens coatings cost money, and the cost of multiple coatings quickly adds up.
• Many opticians ask these questions because they are confused about what an aspheric lens is and how it benefits patients.
• Trivex gets the same advantages as polycarbonate such as 100% protection against UV and superior impact strength.
• Clearly, controlling one’s cost of goods while delivering fashionable, attractively-finished prescription eyewear are important business concerns.
• Generally, lenses with a higher index of refraction will be thinner than lenses with less index.

Can you imagine an optical business trying to survive today by offering only glass or CR-39 lenses, the preferred materials from the 20th century? Polycarbonate was the original high index lens material and was introduced in 1983. It provided the ability to make thinner and lighter lenses. It has great impact resistance, but poor optical qualities in comparison with newer technological breakthroughs, such as high index polyurethane plastic. The advantage of this kind of eyeglass lens material is that it protects your eyes from the damaging effects of the sun. The UV treatment is easy to put up the lenses and is often included with the purchase of eyeglasses. No eyeglass lens material – not even glass – is scratch-proof.

You Can Find Different Lens Materials To Meet Up Different Needs

• Trivex is really a relatively new material that is much like polycarbonate lenses but with top quality optics, and therefore provides clearer vision.
• While no sunglasses lenses are 100% scratch-proof, you can purchase scratch-resistant lenses the next time you’re in the market for new sunglasses.
• Significant astigmatism, greater than 1.50D, can only just be properly optimized peripherally with a well-designed free-form lens.
• Polycarbonate plastic comes with an index of refraction of just one 1.586, a specific gravity of 1 1.20, and is very impact resistant.
• This UV treatment will not change the appearance of the lenses and is fairly inexpensive.

Aspheric means that instead of having a round, or spherical curve on leading surface, the curve gradually changes from the biggest market of the lens to the periphery of the lens. The curvature in a minus lens are certain to get gradually steeper toward the periphery and an advantage lens curvature will gradually flatten toward the periphery. This is important since it provides consistent optical clarity in the lens periphery, not just the center. It also makes it possible for someone with a solid prescription to wear a more substantial collection of frames without worry of the lenses being too thick. This not merely affects the looks of the lens but also reduces the enlarged appearance of eyes (“bug-eyed” look) with high plus power prescriptions that are used for farsightedness. The contrary occurs in high minus power lenses for nearsightedness.

How Would You Clean Trivex Lenses?

While this coating does protect the lens it is not a guarantee that they are “scratch proof“. Created from high-quality glass, these lenses feature 100% UV protection, scratch-resistant lenses and durable nylon frames. Polycarbonate and Trivex lenses tend to be more impact-resistant than glass and plastic lenses, and both will often have an integral scratch-resistant coating. This coating can also make their surface nearly as hard as glass. Trivex has the same advantages as polycarbonate such as 100% protection against UV and superior impact strength.
Polycarbonate and Trivex lenses provide greater impact resistance than lenses made out of other materials. They are crafted from softer plastic compounds making them less brittle than other lenses and, consequently, in a position to absorb impacts without cracking, fracturing or shattering. In the decade it was launched, tinted lenses were an extremely popular option for eyeglasses. Because the poly substrate itself cannot be tinted, a revised kind of tintable scratch-coating required research, development and testing.

Kids’ lenses, especially, reap the benefits of a scratch-resistant hard coat. The amount of light reflected depends upon the lens material. Conventional glass or plastic lenses reflect about 8% of incident light, so only 92% of available light enters the eye for vision. Thinner, lighter lenses manufactured from high index materials reflect up to 50% more light than regular glass or plastic lenses (up to 12% of available light).
Polarized lenses eliminate virtually all glare, reducing eye strain and increasing visibility. Polarized lenses will be the most effective way to lessen glare. If you have problems with glare, reflections, or “ghost images,” you may reap the benefits of an anti-reflective coating on your lenses. For lenses minus the coating, much of the light reflects off the lenses and may produce glare or reduce clarity of vision. This coating can make it easier for you yourself to see and easier for others to see you. Stay on top of the latest news about prescription safety glasses, eyewear, sunglasses, and all of the trends in the market. Because of the density of the high index plastic
Trivex lenses have an increased Abbe value so they can produce both sharper central and peripheral vision with less chromatic aberration than polycarbonate lenses. Basically, your vision will undoubtedly be clearer and contain fewer distortions with Trivex lenses.

Normal Index Lenses

Polycarbonate material is lighter and 18% thinner than plastic. This allows for a far more comfortable fit and a far more cosmetically appealing pair of glasses. To learn more on eyeglass lenses, visit All About Vision®. But with regular plastic lenses, a lens treatment is required for these lenses to block all UV rays. This UV treatment will not change the appearance of the lenses and is quite inexpensive.
