Benefits of Various Lenses

If you wear glasses, do you wear the same lenses all the time? It may be time to rethink that. Advances in eyewear have created so many different options that it’s possible to find lenses that make everything you’re doing a little bit easier, from computer work to playing sports and everything in between. In fact, there are so many options that you may be confused about which lenses are right for you. Here, we break down some different types of lenses to help clear up any confusion.

  • Glass lenses are not a great idea. Glass used to be the only option, but it’s heavy and prone to breakage. That’s unfortunate because glass has the best optical clarity, but with all the other choices, it’s just not very practical. Now that there are so many other good options on the market, glass lenses are hardly ever used.
  • CR-39 plastic lenses provide almost as much optical clarity as glass but are half as heavy. They’re also inexpensive, resistant to shattering, and not easily scratched. However, if you have a high prescription, CR-39 lenses will be very thick. Also, while they’re tough enough to handle the stress of regular life, they may not be the best option if you’re rough with your glasses. If you plan to go mountain-biking, for instance, you might want to choose another option.
  • High-index plastic is lighter and thinner than CR-39. High-index lenses come in a variety of prescription options and are compatible with anti-reflective coating.
  • Polycarbonate has been around since the 70’s, but it’s still a popular choice. Lighter and more impact-resistant than CR-39 plastic, polycarbonate was originally developed for safety applications, like bulletproof glass and Air Force helmet visors. It’s a great choice for children’s eyewear, safety glasses, and sports eyewear.
  • Trivex is a lot like polycarbonate, but better. It’s got the same impact-resistant properties, but is lighter weight and is less likely to cause optical distortions in the peripheral vision. Both Trivex and polycarbonate lenses block UV rays without the need for special coating, which is also beneficial.
  • Gunnar lenses make screen time easier on the eyes. That’s because they have a special anti-reflective coating that blocks high-energy artificial blue light, UV light, and glare, in order to protect your vision and reduce eye-strain. They’re expensive, even when they’re not prescription lenses, but it may be worth the money if you spend a lot of time in front of a screen, and you’re experiencing issues like strained, dry, or red eyes, blurred vision, or headaches.
  • Transition lenses work both in and out of the sun. A convenient option, these lenses darken when the wearer goes out into the sunlight, and lighten indoors. This eliminates the need for two pairs of glasses, which saves money and hassle. They come in many different varieties, including shatter-resistant, bifocal and progressive.
