Anyone who wears glasses is aware that when they start practicing sports, their glasses feel like a weight. It becomes uncomfortable and more likely to break once you start to perspire. There are particular prescription glasses available for athletes.
Trivex and polycarbonate lenses both offer qualities that make them suitable choices for eyewear when the wearer may need more protection and durability for activities they engage in.
Such lens materials are advised for usage in sports goggles, sports glasses, and specific safety eyewear (used in industry). They are appropriate for almost all eyeglass frames when additional lens safety is required.
These glasses are primarily made to protect the eyes, making them ideal for children who are prone to accidents or for athletes. Polycarbonate or Trivex is used to make eyeglass frames, which are the most protective. Compared to typical eyeglass frames, these are lighter and slimmer.
Trivex Lenses
Trivex lenses are made of a lightweight and impact-resistant polymer. Trivex lenses were developed by PPG Industries in 2001 as a replacement for polycarbonate lenses. Similar to regular plastic lenses, trivex lenses are created from a monomer with a urethane base
They are produced using a more labor-intensive cast molding technique, much like how regular plastic lenses are constructed. Until it settles, the liquid lens material is progressively baked. PPG claims that Trivex lenses offer finer optics than polycarbonate injection-molded lenses as a result.
Advantages
- Have a look at the main advantages of trivex glasses below:
- Lenses made of the substance trivex are resistant to scratching and shattering.
- Trivex lenses are resistant to damage from acetone and other solvents. They can also survive alcohol as well as isopropyl alcohol.
- Trivex lenses don't have the internal stress that could cause internal lens cracks. They, therefore, don't cause internal cracks or blurred vision.
- Trivex lenses are lightweight. Trivex lenses are more comfortable since their density ratio is lower than that of other plastic lenses. Therefore, it is suitable for senior people.
- As the skin on the nose gets older and more sensitive, wearing light eyewear is fantastic for reducing irritation.
- UV protection from UV-A and UV-B rays is provided by Trivex Lenses.
- You can see naturally wider and without distortion because of the aspheric lens design, which reduces the extra magnification that is done in conventional lenses.
Disadvantages
- You must be familiar with the disadvantages as well:
- Trivex is a brand-new product, therefore finding it in stores can be challenging. Since they are only available online, there is no way for you to test them out in person.
- Prescription Trivex eyeglasses are highly pricey. Other add-ons raise the price even more after the basic lens. Even greater price increases result from progressive lenses.
Do Trivex Lenses Fit Your Needs?
Trivex lenses provide superb optical properties, are exceedingly light, and have excellent impact resistance. These characteristics help to explain why wearing these lenses is so incredibly comfortable. Trivex Lenses provide a tonne of features, but you also need to put in the effort. Trivex lenses are the priciest lenses. Your eye doctor will let you know if Trivex lenses are an appropriate option for you.
Polycarbonate Lenses
Polycarbonate was the first material used for protective prescription eyeglasses in the 1970s. Impact-resistant, lightweight, and comfortable eyewear are available in polycarbonate.
Safety glasses and sports goggles are now made with polycarbonate lenses thanks to significant advancements. To create stronger pairs of glasses without rims and boost durability, rimless glasses also use polycarbonate lenses.
Advantages
- Let’s see what their advantages are, here:
- UV rays from the sun can harm your eyes in addition to causing skin cancer. Polycarbonate lenses on sunglasses offer protection against dangerous UV rays. It lessens the likelihood of eye problems like melanoma, cataracts, and macular degeneration.
- It is thin and lightweight. It is renowned for being incredibly lightweight and is 25% thinner than glass lenses. They are ideal for children and are comfier to wear.
- It provides perfect resistance against impact. It won't break even after being struck by a steel ball traveling at 160 km/h. They are more difficult to scratch or break.
Disadvantages
- Have a look at the disadvantages of polycarbonate glasses below:
- Although eye care is crucial, choosing polycarbonate lenses due to their high cost is more challenging. Your eye doctor can advise you on the cost and value of polycarbonate lenses.
- Trivex lenses are more durable than polycarbonate lenses. They are not Trivex lenses, but they are more streamlined, lighter, and more robust than glass and plastic lenses.
Comparing Trivex and Polycarbonate Lenses
People have worn sunglasses that shield the light for approximately 2,000 years. The technology we have today is thankfully far superior to what was available all those years ago. However, one advantage of this is the accessibility of a wide range of choices, from the toughness of sports sunglasses to the fashionableness of photochromic lenses.
Trivex sunglasses and polycarbonate shatter-resistant sunglasses are the only two basic options for sturdy yet lightweight sunglasses. Let's compare the two in light of their primary characteristics:
Thickness
Trivex lenses, however just marginally thicker than polycarbonate lenses, have a slightly higher index of refraction (1.58 vs 1.53). The lens will consequently be around 10% thinner.
UV Protection
Trivex and polycarbonate lenses both offer 100% UV radiation protection without the need for extra UV-blocking coatings.
Optical Clarity
Each lens has an Abbe number that represents the amount of chromatic aberration that lens has, which is what results in problems like distorted or blurry images. Trivex lenses have better center and peripheral vision with less chromatic aberration than polycarbonate lenses because they have a higher Abbe value. In essence, Trivex lenses will improve the clarity and distortion of your vision.
Weight
Trivex sunglasses use less material overall and are lighter than polycarbonate sunglasses due to the lens's thinner construction. Trivex lenses are made from a urethane-based monomer that is 10% lighter and has a lower specific gravity than polycarbonate. You don't want to feel the sunglasses on your face if you're going to be running, trekking, or competing.
Deflection Resistance
Both lenses are sufficiently shattered and scratch-resistant as a result of their manufacturing method. You won't need to worry about either choice if your only concern is what will happen if your glasses are dropped.
Protection against Scratches
Because these lightweight lens materials are fairly "soft," they can absorb energy without breaking, making them significantly more impact-resistant than standard glass and plastic lenses (including other high-index lenses) (including other high-index lenses). Polycarbonate and Trivex lenses need a scratch-resistant coating because of their flexibility to prevent surface scuffs.
Polycarbonate and Trivex lenses' surfaces can be coated with scratch-resistant materials to make them almost as hard as glass. The majority of eye care professionals provide a lens warranty to guard your lenses against scratches for a predetermined period of regular use.
Conclusion
Selecting the right frame is essential when safeguarding the eyes is the main objective. Both Trivex lenses and premium polycarbonate frames are used to safeguard the eyes while playing sports. When playing sports, it's critical to get lenses designed exclusively for athletics.
These glasses will protect your eye in the event of an accident. Lighter and smaller frames should be used when choosing for kids. Be sure to visit a doctor if you ever sustain an eye injury or have any vision issues while selecting eyeglasses.
