Does Trivex scratch easily?

Also,clean your lenseswith a microfiber cloth and a solution recommended by your optician. Keep in mind that even the very best scratch-resistant coating can’t protect your lenses 100%, so, looking after them is a superb solution to prevent scratching. Polarized sunglassesusually provide UV protection and reduce glare reflected off surfaces, making images appear sharper and clearer. They are designed for both nonprescription and prescription sunglasses.

With regards to eye safety, polycarbonate and Trivex eyeglass lenses are only the main solution. Trivex lenses have less internal stress and may produce sharper central vision than polycarbonate lenses.
The Abbe may be the way of measuring how well an optical material transmits light at different wavelengths and grades color accuracy. A higher Abbe value means that colors will undoubtedly be sharper and clearer as the lightweight material is impact resistant for sports safety glasses or prescription eyeglasses. Some lens materials like polycarbonate and trivex have built-in scratch resistance. However, it’s important to know that not absolutely all scratch-resistant treatments offer equal protection. Since most lens treatments are optional, be sure to ask our staff for a two-sided scratch-resistant treatment that provides the best protection for your new eyewear investment. Trivexsunglasses lenses are comprised of a newer plastic made from a cast molding process similar
This flexibility does mean polycarbonate and Trivex lenses need a scratch-resistant coating to prevent surface scratches. Today’s modern scratch-resistant coatings can make the top of polycarbonate and Trivex lenses nearly as hard as glass. Trivex lenses have a higher Abbe value and may produce sharper peripheral vision with less chromatic aberration than polycarbonate lenses.

They are also lab favorites for use in rimless frames, because polycarbonate lenses can be easily drilled and resist cracking round the drill holes. A disadvantage of polycarbonate is that it’s naturally a soft material causing it to scratch much easier. However, unlike CR-39 basic plastic lenses, a scratch resistant coating is nearly always standard since it is applied once the lenses are made. With higher refractive indexes, you can find often more chromatic aberrations, meaning visual disturbances of light, that can be interpreted as blur by some. The abbe value of polycarbonate is 30, the lowest of most lens materials rendering it the worst lens for optical clarity and integrity. For all those reasons Trivex is the better choice in a mid-index lens. Polycarbonate is a significant improvement in lens material to plastic lenses for a number of reasons2.

Can help extend the life of your sunglasses—because they’re an essential piece of equipment that should be treated as such. Is made from a thermal casting process, where in fact the material is filled right into a cast and allowed to cure over time, several hours, before being removed.

Is Glass Lenses Better Than Plastic?

Let me assist you to understand the various features and upgrades available on glasses lenses. Just as you use sunscreen to keep the sun’s UV rays from harming your skin, UV treatment in eyeglass lenses blocks those same rays from damaging your eyes. Overexposure to ultraviolet light is thought to be a cause of cataracts, retinal damage along with other eye problems. To further protect your eyeglasses from scratches, keep your glasses in a protective case when you’re not wearing them. Also, never clean your lenses without first rinsing them with a cleaning solution or water. Rubbing a dry, dusty or dirty lens with a cleaning cloth or towel can cause scratches, even on lenses with a scratch-resistant coating.
Compared to polycarbonate lenses, Trivex lenses tend to be more flexible and have a tensile strength of 40,000 psi. This means that they could withstand impacts much better than other lens materials so that they provide safety for athletes or individuals who work in hazardous environments like construction workers. Clearly, controlling one’s cost of goods while delivering fashionable, attractively-finished prescription eyewear are essential business concerns. But also for those ECPs who’ve yet to be won over by Trivex, it’s time and energy to reconsider. Can you imagine an optical business attempting to survive today by offering only glass or CR-39 lenses, the preferred materials from the 20th century?

• When lenses are produced from materials with less Abbe value, a certain deviation depending is expected.
• Most people together with your script wouldn’t notice a
• Let’s check out the many lens materials and coatings in the marketplace today.
• They are more likely to separate from the lens with high temperature and may make the lens coating look like it is an irregular texture to create crazing.

Whatever that price breakdown will probably be worth the extra features the material/coating/frame, provides. The point is the individual is informed and will make their choice based upon the information presented to them. I have known way too many patients who were surprised at your options available to them, and wish someone had told them about different materials/ or coatings prior to the point I did.

Regardless of the lens material, eyeglass lenses with AR coating transmit over 99% of available light to the attention. They’re lightweight, impact-resistant, and recommended for children and athletes.
Poly and Trivex have become soft materials ( a better word would be they have more elasticity.) Hence their inherent impact resistancy. Additionally, that is important when mounting lenses in rimless frames because they are less likely to crack or shatter. The best material to make thin lenses—Trivex’s superior impact qualities allow it to be ground to the thinnest edge or center of any lens material.
