About this deal

To figure out which type of sunglasses are best for your eyes and vision health, you’ll want to start with the lenses. Polarized lenses In this article, we would like to go into the differences of sunglasses and have the glass lenses compared to the plastic versions and what you should look for when buying when it comes to configuration. If your face is round, it’s also about as wide as it is long, only with a more rounded jawline. To give yourself some angles, consider square or rectangular frame shapes, but avoid oversized frames that can add too much width. Aviator frames, with their slight curve, may also be a great choice for you. Brown/amber lenses. This lens tint can enhance depth perception. While brown/amber lenses are great for pilots, sailors and golfers seeking clarity on sunny days, they tend not to work well on cloudy days. 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.

The best sunglasses are the ones you actually wear, which means they need to fit comfortably. You shouldn’t feel any pressure at the sides of your head or behind your ears, and they should fit securely over the bridge of your nose without slipping or pinching. Some people like nose pads because they allow for a more customized fit, while others dislike them because they can tangle in your hair. A good pair of sunglasses should also prevent uncomfortable eye strain. Dr. Lin says that 100-percent UVA and UVB protection is key in this respect, as is enough tint that you’re unable to see your eyes through the lenses when looking in the mirror. Both are viable lens materials. Glass is extremely scratch resistant, can provide a very high refractive index, but is more fragile to hard impacts. Polycarbonate is also hard wearing and has great impact resistance, but has a slightly lower refractive index. If you want hard-wearing lenses, polycarbonate or Trivex are safer for sport or protective prescription eyewear.If you regularly play sport or have a manual labour job, the fragility and weight of glass makes plastic lenses as a much safer, more forgiving lens option. If you want a lightweight frame for intense physical use, sports glasses with CR39, polycarbonate or Trivex lenses are better suited. Polarised lenses are a sunglasses-specific lens designed to reduce glare and improve visual clarity. They use a chemical filter within or upon the lens which diminishes reflected glare from flat shiny surfaces such as water, snow or ice. They're especially popular for water-sports or driving to reduce visual fatigue over long periods of exposure. They can be CR39, polycarbonate or glass. Plastic lenses also lead the way in terms of safety and durability. These lenses pose a lower risk of injury, making them better suited for children, teens and active adults. Those with a sensitivity to light, such as people who have undergone cataract surgery, can also benefit from polarized sunglasses. Non-polarized lenses These well-crafted, American-made sunglasses have a sophisticated, timeless design and outstanding lenses.

No particular lens material is “best.” This depends on your prescription, lifestyle and budget. Glass is optically superior but is also prone to shattering and can be very heavy if you have a high sphere and /or high cyl prescription. 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. If you’re in the market for a new pair of sunglasses, you’ve probably realized that there are plenty of lens options available — namely, glass and plastic. But do glass or plastic lenses make more sense for sunglasses? It’s also worth noting that sunglasses should be worn on cloudy days as well, since UV rays can penetrate clouds. On top of sun protection, cyclists, boaters and other outdoor enthusiasts need a layer of protection to shield their eyes from branches, debris and other airborne hazards. Types of lensesVERSATILITY: Plastic lenses are offered in a wider variety of colors and designs than glass lenses. Plastic also tends to be a better choice for sunglasses due to the coating and color options. WEIGHING YOUR SUNGLASSES OPTIONS? Shop for sunglasses at an optical store near you or an online eyewear retailer. Sunglass lens replacement: Plastic lenses Glass lenses tend to be limiting in terms of frame options and tinting capabilities. Your need for prescription vs. non-prescription sunglasses will also likely affect your decision.

Activity: When choosing a pair of sunglasses, consider what you plan on doing with them. While some styles can bridge the gap between activities like cycling or running and brunch with friends, like Smith's Lowdown 2 or the Fuse Egmont. Some sunglasses meant for sports may look out of place on a date, while some fashion sunnies may not stand up to sweat and wear from hard workouts. 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. We also appreciated their weight, which reinforces the impression of superior craftsmanship and suggests they should last a long time if cared for properly. The sunglasses offer a snug, comfortable fit ideal for leisure pursuits (although one of our testers did find that there was some light leakage around the edge of the frame on particularly bright days). The lenses are made of mineral glass for the best quality optics, definition, and contrast, with an anti-reflective coating and 100-percent UV protection. Choose from five gorgeous colors, including Blush and Tortoise. An oval face is slightly longer than it is wide. The good news if this describes you: Just about any style of frame can work, so try aviators, Wayfarers, wraparounds or any geometric shape that suits your personality. There is an endless list of lens treatments which you can apply to your sunglass lenses, such as anti-scratch, anti-glare, anti-reflective, a UV protective coating, a mirrored coating or even a polarized coating.We found that there was a slight resistance when unfolding the arms—a pro because it gave us confidence in the hinges and their ability to hold the arms in place at any angle. The polarized CR-39 lenses offer superior clarity and glare elimination, while the level of tinting is just right. As for fit, both our testers found the sunglasses secure and flawlessly comfortable, even after several hours of wear. They come with a premium hard case and polishing cloth, in a range of colorways from Clear with a Polarized Blue Smoke lens to Honey with a Green Polarized lens. All the above manufacturers have different tints in the program, which have different contrasts. It is best to test out the different lenses on a sunny day before buying and pay attention to details in your surroundings, for example edges on houses or shading, to determine where the contrasts are most comfortable for you.
