Polarized Vs Polycarbonate

We won’t elaborate too much on these types as they are not observed in the safety industry. One type, however, that is often grouped with the plastics is CR-39. This is still popular — not for safety, but for sunglasses and prescription eyewear. Regular eyeglass frames are not rated for use as safety glasses and typically don’t provide the type of eye protection necessary for sports.

Trivex lenses could be most closely in comparison to glass or mineral lenses when it comes to offering superior optical quality. Trivex has a significantly higher ABBE value than polycarbonate, which measures the chromatic aberration, aka clarity, of a particular lens material. Virtue Chromatic lenses are fused with a heavy-duty metallic scratch and impact-resistant coating that maximizes durability without sacrificing optical clarity or altering color balance.

• As it is still among the fastest growing segments in eyewear, polarized sunglasses and safety glasses are available in a variety of styles and tints for men and women.
• It is the heaviest of our four materials but is 35% thinner and lighter than standard glass.
• Costa lenses exceed polarization to save your eyes from the sun鈥檚 harmful rays and improve your overall experience.
• Having the ability to create more precise lens prescriptions, the clarity of view is increased by at the very least 20%.
• Today, modern interpretations of this frame shape are the rage and seen on faces of countless celebs.

It is useful for the helmet visors of astronauts and for space shuttle windshields. Polycarbonate was adapted for use in eyeglass lenses in reaction to demand for lightweight, impact-resistant lenses. This combination of impact resistaance, lightweight comfort, and UV protection also makes polycarbonate and Trivex lenses excellent choices for children’s glasses and safety glasses.

The initial lightweight Plastic eyeglass lens made its debut sometime in 1947. Since then, plastic has become a popular and widely used material to make eyeglass lenses. In this article, we are going to be discussing specifically plastic and polycarbonate eyeglasses and the major differences between both lens materials. Those pesky bright reflections of the sun on the cars ahead can sometimes be attenuated much. They tend to be horizontally polarized, thus ideal for vertically polarized sunglasses. However, if sunlight is relatively low behind you, the sun rays will undoubtedly be near perpendicular to the reflecting surfaces which won’t polarize the light. The sunglasses will help more with the reflections from the glass than from the metal as the former are polarized to an increased degree.

With TAC, because the polarised film is on the front it can scratch and finally lose a few of its polarising properties. On higher priced polarised sunglasses (typically above 拢60) the lens material is likely to be polycarbonate. Here the polarised film is sandwiched between two layers of polycarbonate meaning the polarised film can’t ever wear out. Importantly, a polarised polycarbonate lens also provides impact protection. Most lenses in prescription spectacles made today work with a plastic called CR-39 or a very close copy since the material is owned by a company called PPG.

Scratch Resistant

The lightness or darkness of a lens is normally measured by its VLT. Visible Light Transmission is how much of the 100% available white light passes through the lens. Using solvents that are not compatible with polycarbonate can lead to the softening, crazing, and/or cracking of the plastic part. Run water on the dirtied lens, both front and back, to clean away debris. Gently dry with a clean, non-abrasive cloth, with slow wipes within a direction. With cloth at hand, carefully wipe dust or debris from your lenses. Moderate pressure is acceptable with a clean cloth and usually sufficient for stubborn spots or smudges.

If you are searching for a new eyeglass make sure to find out the lens materials available. You can then apply the info you have on both lenses to determine which will suit your needs best.

Polycarbonate聽Lenses Summary

The methods used to create optical lenses using this material have become quite advanced. For children’s eyewear, select a sturdy frame and lightweight polycarbonate or Trivex lenses. Polycarbonate lenses are thin, lightweight, and incredibly impact resistant. They鈥檙e the go-to lens material for safety glasses and extremely versatile when it comes to outfitting them with features such as Transitions, polarization, or other feature combinations. As an industry-standard, polycarbonate lenses are affordable and inherently UV-protected.
