Product Information

These sexy '70s-style oversized frames that will up your cool factor without emptying your wallet and punch way above their weight. They’re certainly old fashioned, but glass lenses are still the most optically efficient material for making optical lenses. The Topekas are super light and flexible making them perfect for traveling. They're also sporty and stylish, eco-friendly, and decently priced. Sunglasses with glass lenses also have their disadvantages. One disadvantage is that sunglasses made of glass might shatter in case of a fall. On the other hand, they are somewhat heavier than the sunglasses with plastic lenses. Green lenses are also good for all day use as they protect your eyes while providing visual clarity that most resembles natural human eyesight. Brown or amber tinted lenses have a red tint which is known to enhance color contrasts, so they are best suited for sports or activities where accurate depth perception is key, such as tennis, fishing, golf, and sailing.

This is not annoying in most cases. Once you know the pros and cons and have looked through the lenses yourself (testing different tints) you can decide which is the best lens configuration.Take a look at the pictures of older sunglasses with glass lenses (approx.40 years old) and sunglasses with plastic lenses (approx. 5 years old), which were used daily for approx. 20 minutes. The picture shows on the right side an old pair of sunglasses with real glass lenses, which is about 40 years old. The surface is flawless. In contrast, on the left side you can see a pair of sunglasses that is about 5 years old, which is equipped with plastic lenses. this shows one on the surface many small scratches, which also disturb the vision. What Are the Disadvantages of Glass Lenses in Sunglasses Compared to Sunglasses With Plastic Lenses?

Glass lenses can shatter upon hard impact which poses a more significant danger compared to plastic-based lens materials. Lenses made from resin polycarbonate or CR39 resin don’t shatter like this, which is they’re deemed safer, especially for sporting activities. As a kid, I lusted after the Ray-Ban Aviators. As an adult, after I'd finally made the upgrade from cheaper imitations, the brand's quality and craftsmanship made me that much more of a fan, especially when behind the wheel. Just ask any state trooper. The Ray Ban Aviators are classics that have been around since the late 1930s when they were designed for the US Army pilots (before the birth of the U.S. Air Force). And if they were the go-to for flying aces, they definitely make the cut for commuting. These iconic shades worn by "The Dude" in The Big Lebowski have large masculine frames encircling the brand's famous polarized lenses, providing crystal-clear color and depth.Before you make a sunglasses decision, take a look at the benefits and limitations of both glass and plastic lenses. When it’s time to select a new pair of shades, it will be much easier to make the right choice. Glass lenses are also known as mineral lenses or crown glass lenses. These names refer to the alkali-lime silicates they’re made from instead of the commonly used polymer-based CR39 optical lenses. The experience with glass lenses in sunglasses is consistently positive. Very few prospective customers complain about the higher weight. However, it is usually noticed that the glasses still have scratched lenses even after years. And that, of course, is a big advantage.
