Sunglasses enjoy enormous popularity all around the world. About half of all Australians wear them, and 95.9 million pairs were sold in the U.S. in 2012. About 58% of adults report that they even make their children wear them, and for good reason. Sunglasses are designed to protect the eyes from the sun’s harmful rays, and polarized varieties even limit the types of light that can pass through the lens, ensuring that your eyes are kept safe.
What many people don’t realize is that polarized lenses need to be replaced every year or two in order to continue effectively guarding your eyes. That doesn’t mean you need to invest in a whole new pair, though! Replacing sunglass lenses is much easier than you might think, especially now that sunglass lens replacement companies make all kinds of lenses available. Here, we’ll look at the process you go through to replace lenses in sunglasses, answering questions like, “How do you measure for sunglasses?” to “How do I install my new lenses?” Let’s use Ray Ban Wayfarers for the sake of argument.
How to Measure Ray Ban Lens Size
We’ll show you how to measure Ray Ban lens size, but it’s only fair to first let you know that you don’t really have to. On the inside of one of the sunglasses’ arms, you’ll find a series of letters and numbers. It might look something like this: MOD.6033 116/13 5916 125. The four digits after “MOD” are the model number. You’ll need that information. The number right in front of the  is the maximum width of your lenses, which is also necessary information. Just to be sure that information is correct, however, you should learn how to measure Ray Ban lens size. Measure in a straight line across the widest part of your lens, allowing between 1/2 and 2 mm for the portion of the lens hidden under the frame.
How to Install Your New Lenses
Begin by removing your old lenses. Loosen the screws holding metal frames together or soak plastic frames in hot, soapy water. Then, pop the old lenses out. New lenses should pop in relatively easily if you start at the bottom. Be sure they’re well-aligned before tightening any loose screws.
Just by replacing your polarized lenses, you can help make sure your eyes and the thin skin around them are protected from the potentially harmful UV rays cast by the sun. It’s easier than you think! Learn more about this topic here.
