Ask for "polaroid sunglasses" in a lot of shops and you will be handed a polarized pair without anyone blinking. The two words have been used as if they mean the same thing for decades. They don't, quite, and the difference is worth thirty seconds of your time before you buy.
Polarized is the technology
Polarized describes what a lens does. Light bouncing off a flat surface, like a road, a car hood or the sea, comes back concentrated in one direction. That is glare, the hard white shine that makes you squint. A polarized lens has a filter built in that blocks light traveling in that direction while letting the rest through.
The result is less glare, better contrast and colors that look the way they are supposed to. It is not the same as a darker tint. A dark lens turns everything down. A polarized lens takes out the reflection specifically.
Polaroid is a brand
Polaroid is a company name. In 1929 the inventor Edwin Land created the first polarizing material made for commercial use, and called it Polaroid. His company started making polarized sunglasses in the 1930s, and they sold so well that the brand name stuck to the technology, the same way people say Kleenex for a tissue or Band-Aid for a bandage.
Polaroid still exists as an eyewear brand today. So a pair of Polaroid sunglasses is a brand, and a pair of polarized sunglasses is a lens type. Plenty of brands, Vibes included, make polarized lenses.
Why the mix-up matters when you buy
Because "polaroid" gets used loosely, a listing that says polaroid lenses might mean properly polarized, or it might just be using a word that sounds technical. The same goes for "anti-glare", which can mean a polarizing filter or nothing at all.
What to look for instead:
- The word polarized in the product description, spelled out.
- UV400 listed separately. Polarization deals with glare. UV400 blocks ultraviolet light up to 400 nanometers. They are two different jobs, and a good pair does both.
- A test you can do yourself. If you already have the pair, our guide on how to tell if sunglasses are polarized takes ten seconds.
When you want polarized, and when you don't
Polarized earns its place anywhere there is reflected light: driving, beaches, boats, snow, wet pavements, long days outside. If that is your week, it is the lens to buy.
It is less useful if you spend a lot of time reading screens outdoors, since some LCD displays go dark or patchy through a polarized lens. We go through the full trade-off in polarized vs non-polarized sunglasses.
Where to start in the range
Most of the Vibes range is polarized, so you can pick on shape first. Loft is the easy everyday square, polarized and the one people grab without thinking. Marlow is the same idea with a mirror finish and a flexible TR90 frame. Sasha is the flat-top square with mirrored polarized lenses if you want more presence.
Frequently Asked Questions
No. Polarized is a lens technology that cuts reflected glare. Polaroid is the brand that first sold polarizing material, and its name became shorthand for the technology. Many brands make polarized lenses.
Polaroid made the first commercial polarizing material in 1929 and polarized sunglasses soon after. The brand was so tied to the technology that the name became the everyday word for it.
Not automatically. Polarization reduces glare, while UV protection blocks ultraviolet light. Look for both on the label, ideally written as polarized and UV400.
Look at a phone or laptop screen through the lens and rotate the glasses slowly. If the screen darkens at one angle, the lens is polarized.
