Are Trivex lenses thinner than polycarbonate?

Although more expansive than traditional glass lenses, polycarbonate lenses offer durability, UV protection, and better clarity of vision. Trivex is one of the newest optical materials in the marketplace. It combines the very best features of polycarbonate (scratch and impact resistance, UV protection, thin, and light-weight) with the great optical qualities of CR-39 plastic and glass. This implies that patients with higher prescriptions should experience much better optics through their lenses- especially through the peripheral portions of their lenses. Made up of a dense, plastic-like material, polycarbonate is very impact resistant.

Most eye care professionals provide a lens warranty to protect your lenses against scratches for a specified amount of normal use. Polycarbonate lenses are available in a wider variance of lens designs (e.g., progressive lenses along with other multifocals) than Trivex lenses. Another advantage is that it reduces the distorted appearance of the patient’s eyes, as seen by a person looking at the individual through the lenses. An aspheric lens in this same prescription would make the patient’s eyes appear much closer to their actual size. Not merely do anti-reflective coatings eliminate reflections on glasses, they can help you create better eye contact. This feature makes glasses virtually invisible, and might even eliminate those glare spots in photos. BLUE LIGHT PROTECTIONreduces eye fatigue to supply a strain-free visual experience, while providing the most complete protection from harmful blue light.
in vacuum pressure expressed as a ratio. Light travels fastest in a vacuum and slower through different materials. Trivex lenses are an excellent choice if safety can be an issue or you lead a dynamic lifestyle. Progressive lenses can raise the price, because they provide a more gradual modification in lens strength for clearer vision at any distance. Aspheric and atoric lens designs reduce unwanted magnification and minification within more traditional eyewear. These types of design also increase the peripheral view by eliminating distortion. Trivex includes a high Abbe value that offers clean, sharp vision.

Why To Prescribe Lenses Made From Trivex Material?

To greatly help clean your glasses effectively, you can expect High Performance lens care & cleaning supplies. On your next visit, we’re happy to demonstrate the easiest way to clean your glasses. Various high index lenses can be found today in different price points based on how much thinner they are compared with regular plastic lenses. The lenses are classified by their “index of refraction” (or “refractive index”). Both Polycarbonate and Trivex lenses have equally great ratings in these areas.
This implies you won’t get yourself a possiblity to test or have the material beforehand. Children can also benefit from Trivex glasses, being that they are more susceptible to forgetting, dropping, crushing, or damaging their glasses. Shop online at SafeVision.com and discover both polycarbonate and Trivex lenses for your industry or sport. CR-39 lenses have a higher Abbe value of 59.3 making them the lenses with minimal distortion from dispersion/chromatic aberration.

He has covered different medical specialties from infectious diseases and pneumology to breast cancer and cosmetic surgery.

In fact, they are 10 percent lighter than polycarbonate lenses. Anti-reflective coating reduces lens reflections and allows more light to enter the attention for better night vision. Regardless of the lens material, eyeglass lenses with AR coating transmit over 99% of available light to the eye. Though aspheric lenses offer advantages of all prescriptions, they are particularly beneficial should you be farsighted. Aspheric lenses greatly reduce the magnified, “bug-eye” look due to regular, highly curved lenses for farsightedness, and they help reduce the “bulge” of the lenses from the frame. And since they have a slim profile, aspheric lenses have less lens mass, making them much lighter.

Inherent UV protection and wide product availability also donate to its popularity. For children’s eyewear, choose a sturdy frame and lightweight polycarbonate or Trivex 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 around 30% lighter than regular plastic lenses, making them a great choice for anyone who is sensitive to the weight of eyeglasses on their nose. Without doubt, polycarbonate lenses have become the standard of branded safety glasses, sunglasses, and goggles.
While no lens is scratch-proof, this special coating does make lenses harder to scratch when dropped or rubbed against a hard surface.

• Aspheric means that rather than having a round, or spherical curve on the front surface, the curve gradually changes from the center of the lens to the periphery of the lens.

for the helmet visors of astronauts and for space shuttle windshields. Polycarbonate was adapted for used in eyeglass lenses in reaction to demand for lightweight, impact-resistant lenses.

Pros & Cons Of Polycarbonate Lenses

Should you have any questions about eyeglass lenses (or any optical topics!), just ask one of our friendly opticians! We are always happy to show you demo lenses to help you actually see what we are describing in this article. Put in another way, if you looked down on the front surface of an aspheric lens, it would have a minute “bullseye” pattern over the lens.
