   Clarity and Quality

   Those original opticians had it right when it came to optical clarity. Glass lenses can’t be beaten. And that’s why when exact precision is needed, say in microscopes, cameras, or telescopes, glass is still the standard. But that doesn’t mean polycarbonate or plastic lenses are not clear. High-quality polycarbonate lenses offer excellent clarity for a pair of eyeglasses or sunglasses. The truth is that our eyes can’t really detect the difference in clarity between glass and high-quality polyc...

   Impact Protection

   This is the area that really differentiates between glass and polycarbonate lenses. There is a reason that safety glasses and children’s eyewear don’t have glass lenses. And that reason is impact protection. Even the most modern glass lens is more likely to break or shatter than a polycarbonate lens. That’s because Polycarbonate flexes instead of shattering when hit by an object, whether it’s gravel, a ball, or an elbow. And since manufacturers of sports eyewear understand that frames get dro...

   Weight

   Glass lenses used to be really heavy. And wearing them for long periods of time was a chore. One of the biggest selling points of early plastic lens material was that it was lightweight and offered all-day comfort. Today, even though glass lenses are thinner than they used to be, polycarbonate lenses are still the lighter choice.And if you combine them with a lightweight frame material like titanium or nylon, you’re set for a full day of comfortable wear.
