Prescription lenses. Do you need vision correction when driving or for other outdoor activities? If you have even a small amount of refractive error, correcting your outdoor vision with rx sunglasses will help you see more clearly and comfortably in bright sunlight. The first step to getting the best outdoor vision possible is to schedule an eye exam. 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. 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.
The first plastic eyeglass lenses were introduced by Armorlite Lens Company in California in 1947. While there have been numerous advances in eyeglasses since then, CR-39 plastic is still known for its excellent optical quality, durability and low cost. Pros: A super stylish pair of sunnies that doesn't scream" smart glasses;" easy to set up and operate. If your prescription has an exceptionally strong sphere or cylinder power, the refractive index of glass can be better for minimising bulky lenses. Using the correct index, glass can normally be made thinner than a plastic equivalent.Choosing sunglasses isn’t all about sun protection and visual performance, of course. You also want your shades to flatter you. A good place to start is determining the shape of your face — from there, you can get a sense of which styles do and don’t work for you.
The advantages with classic glass lenses are the surface hardness and better optical quality of glass lenses over plastic lenses. Sunglasses with glass lenses have a higher abbe number than plastic lenses. There are actually sunglass wearers who can see the difference when they look through a real mineral lens and then look through a plastic lens. However, this is not the case for everyone.
Glass lenses are a classic choice and provide optimum clarity. But they can be really heavy, and if you’ve got a prescription, they get even heavier. Not to mention glass lenses are not the safest choice for eyewear, especially for kids.
A recommendation from our side are the sunglasses from Maui Jim and Etnia Barcelona. In terms of durability, all sunglasses are virtually the same when it comes to scratch resistance. Whilst glass has a high refractive index, there are various brand options available. Zeiss, Hoya, Essilor, Nikon, Seiko and Shamir etc. Depending on your prescription and lifestyle, real glass lenses may or may not be suitable. 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. But this type of sunglasses isn’t only for outdoors enthusiasts; anyone who finds the sun’s glare uncomfortable can get relief from these advanced lenses. For instance, many motorists like polarized sunglasses because they reduce glare reflecting from other vehicles or off of light-colored pavement.You've probably heard the term "polarized" in regard to sunglasses, but what does that really mean, and is it an important factor when choosing a pair of sunnies? I spoke with two ophthalmologists, Drs. Lisa Park and Natasha Herz, who explained that polarized lenses prevent glare from entering the eye horizontally. Wearing a pair can help protect your eyes from any polarized light reflecting off shiny surfaces like water or car hoods. So not only are they great for activities like fishing and water sports, but also for driving, running, or biking. However, the hue of your lenses still plays an important factor regarding visual performance. Some colors are more suited for certain activities, so it is still worth considering which lens color will be best for your sunglasses. Despite their extra weight, you may prefer glass lenses compared to plastic ones, depending on your prescription and personal preferences.
