Polycarbonate Lenses Vs Trivex

Thinner, lighter lenses made of high index materials reflect up to 50% more light than regular glass or plastic lenses (up to 12% of available light). When we educate parents concerning the great things about higher-quality lenses, most parents desire to provide their child with the perfect eyewear. But the the truth is not all of them can afford the perfect lenses. In these cases, we use parents to prioritize the most important features to include in their child’s eyeglasses.

Performs much like polycarbonate with regard to their weight, durability index and UV protection. We’ll lay out the reality, put the lenses to the test, and try to put the question to rest. However, Tyler says that you will get what you purchase, so the price difference will probably be worth it. It’s an upgrade from the standard kind of plastic (called CR-39), but nonetheless not pricey.

Trivex Lenses Vs Polycarbonate

Polycarbonate has a specific amount of internal stress, as do many materials. However, internal stress could cause birefringence, or small internal cracks and fractures that lead to cloudy or blurry vision as time passes with glasses. In contrast, Trivex does not have any internal stress because of how it really is manufactured, so it won’t experience this sort of breakage. Unfortunately, because they are newer and made from a specific type of plastic, Trivex lenses may not be available in all elements of the United States. Your vision insurance might not be able to cover the cost of this lens material. Finally, Trivex can undergo many surface treatments, including anti-reflective, hard coatings, and tinting.

• Trivex’s density is 16% lighter than common plastic lenses and 8% lighter than Polycarbonate.
• Additionally, that is important when mounting lenses in rimless frames as they are less inclined to crack or shatter.
• This means that rather than having a round (or “spherical”) curve on leading surface, these lenses have a curve that gradually changes from the center to the lens to the periphery.
• The ultraviolet protection, great visual clarity, and strong material make them a good choice for those with active lifestyles, like
• Other benefits include resistance to chemicals and better light refraction.

People who enjoy the outdoors or work consistently outdoors can benefit from Trivex. The ultraviolet protection, great visual clarity, and strong material make them a good choice for those with active lifestyles, like hikers or runners. Trivex was originally developed for military use by PPG Industries in 2001. The business then took this ultra-strong, lightweight material and applied it to consumer optical needs. Even so, clear vision with several safety features is essential to many glasses wearers.

could easily be dislodged or break into the eye. Strong lenses, and frames, are essential to avoiding eye damage. Lenses shield our optics from potentially dangerous elements – harmful sun-rays, water, debris and, even, our fellow competitors. Actually, I believe trivex has better optics than high index.
Polycarbonate lenses are created from a kind of plastic that is more impact-resistant than standard plastic lenses. This article reviews the different lens material choices for glasses. You can use these details to choose which eyeglasses lens material type is right for you personally. In today’s age of technology, their place in optical has become very limited. The newer plastic lens technologies offer much safer choices that are quite durable as well. Generally, Blaine Eye Clinic strongly discourages the usage of glass lenses.

Regarding impact resistance, it is possible to feel confident that both these glasses will survive being dropped and collisions thanks to shatter- and scratch-resistant materials. Lenses are lighter than polycarbonate lenses, they’re convenient to wear all day. Check out reviews of Breakline sunglasses to hear what others have to say.

An anti-reflective coating is put on eyeglass lenses to reduce how much internal and external reflections on a lens. This coating escalates the quantity of light transmitted through the lens, which improves the caliber of vision. Trivex includes a low index of 1 1.53, much like standard plastic. High index plastic’s index ranges from 1.67 to at least one 1.74, making it considerably thinner and much more lightweight than Trivex, especially in higher prescriptions. High index plastic has similar scratch resistance to Trivex. Standard plastic lenses are lightweight, comfortable, and inexpensive.
Trivex has a significantly higher ABBE value than polycarbonate, which measures the chromatic aberration, aka clarity, of a particular lens material. Regular eyeglass frames aren’t rated for use as safety glasses and typically do not provide the type of eye protection needed for sports. Tyler uses it in all his glasses because it’s the lightest lens material and is as impact-resistant, or even more so, than PC. Regular eyeglass frames aren’t rated for use as safety glasses and typically don’t provide the kind of eye protection needed for sports. This mix of impact resistaance, lightweight comfort, and UV protection also makes polycarbonate and Trivex lenses excellent options for children’s glasses and safety glasses. Just as you use sunscreen to help keep the sun’s UV rays from harming your skin layer, 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.
resistance like Polycarbonate. Trivex lenses could be most closely compared to glass or mineral lenses in terms of offering superior optical quality.
PPG Industries adapted the technology for the optical industry. The material was given the name “Trivex” because of its three main properties which are good optics, lightweight, and strength. Materials with a higher Abbe value provide clearer and crisper visual clarity. Optical clarity;Trivex lenses have a higher Abbe value and could produce sharper peripheral vision with less chromatic aberration than polycarbonate lenses. Our informal tests show the difference is highly subjective.
