Why do I need polarized sunglasses?
A harsh blinding blast of sunlight. A reflection off of snow, or water, or glass, or the roof of the car driving past you while you’re hoofin’ it down a busy road. That my friends, is what we call glare. You’ve felt it. Unless, you’re a freak that exclusively runs on treadmills, or on a windowless indoor track. Depressing, but you do you. (You also might want to consider getting checked to see if you’re a vampire, just to be safe.) Glare has the power to distort colors, make details blurry, and exhausts your peepers. Many individuals that have been victims of glare will say that, “prolonged exposure (of glare) even gives them headaches and that polarized sunglasses are game changers.” Hey, they said it. Not us.
So what are polarized sunglasses and how are they different from non-polarized sunglasses? The polarization is a filter that comes from a thin layer in the lenses, a layer that non-polarized sunglasses do not possess. When vertical light hits a horizontal surface, it creates an especially harsh glare that ranges from feeling like a fly buzzing around your head-- you know, the kind that seems like he’s trying to be your friend-- to being dangerously blinding. Quite a drastic scale. So, the polarized filter comes in and dropkicks the light that bounces off horizontally right in its metaphorical chest. (And if you’re anything like the person writing this content, you’ll also enjoy this entertaining one minute distraction, a compilation of 32 spectacular dropkicks.) In other words, the lenses allow vertical light through, while blocking the intense reflective glare from horizontal light. Meaning, light that bounces off of objects horizontally does not stand a chance, and therefore these lenses significantly reduce glare.
For this reason, polarized lenses are extremely important when it comes to running in sunglasses. Gosh, especially driving. With the amount of glass and metal surfaces you’re surrounded by, the chance of getting your eyes blasted by glare is high. Not only will glare be blocked, but the lenses also boost the contrast in your vision, making details more defined. If you’re someone who likes to fish, this is why polarized sunglasses are said to be the key to spotting fish below the water’s surface.
One complaint all polarized sunglasses companies get is the fact that polarized lenses make it difficult to see LCDs, no, not LSD. LCD, or liquid crystal displays. These are found in many digital screens, including phones and vehicle dashboards. It’s a big, “no, no,” for pilots while flying planes to wear polarized sunglasses… and we’re thankful for that rule. We need our pilots to be able to clearly read the LCDs on their instruments.
So if you’ve learned anything in this rambling hunk o’ chunk o’ text it is this:
