What are the benefits of polarized sunglasses
Polarized sunglasses come with ultraviolet coating improve vision by making colors appear deeper and bolder and eliminating uncomfortable and often dangerous glare.
The first benefit of polarized sunglasses is that they provide clearer vision. The lenses are built to filter bright light. Without the glare, you will be able to see much clearer. In addition, the lenses will improve the contrast and visual clarity.
Another benefit of polarized sunglasses is that they will reduce your eye strain while working outside. As mentioned before, they will minimize glare and reflection.
Darkly tinted sunglasses without UV protection can potentially do more harm than good, as the darkness of the lens can cause the pupil to dilate, allowing damaging ultraviolet rays into the inner parts of the eye.
Polarized sunglasses can benefit your eyesight in all sorts of ways: They reduce glare, boost colors and make daytime driving easier, by reducing windshield glare making your view of the road a little more like the view you’d have without a windshield at all. Driving is safer when you can focus on the road instead of having to adjust your view or shield your eyes from bright streaks of light.
Lastly, polarized sunglasses will allow for the true perception of colors that you may have not been getting with regular sunglass lenses.
What is polarization?
This is how polarized sunglasses get their best feature: the reduction or elimination of glare.
Reflected light waves, glare included, are often horizontal in nature; they have a harder time getting past the vertical filter of a polarized lens.
When light comes directly from a source, its light waves travel vertically, horizontally and all sorts of angles in between. A polarized lens filters this “raw” light and allows only vertical waves to pass through.
Polarized lenses vs. UV protection
According to the American Academy of Ophthalmology, many polarized sunglasses on the market include a UV protection coating. Be sure to read the tags on sunglasses next time you’re shopping for a pair.
Polarized lenses and UV-protected lenses aren’t the same thing. So, it’s important to remember that polarized lenses don’t provide UV protection unless otherwise labeled.
UV protection alone also doesn’t make a pair of sunglasses effective against reflected beams of light and glare.
UV-protected lenses work by shielding your eyes against harmful UV exposure, which is linked to cataracts and eye damage. Even short-term exposure to harsh UV light can cause temporary blindness, or photokeratitis. It’s important to always wear sunglasses with 99 or 100% UV protection when you’re outside.
However, since UV lenses don’t prevent glare, you should look for sunglasses that are both polarized and offer UV protection.
Are polarized sunglasses better?
Polarized lenses aren’t for everyone. But if they’re right for you, they might change the way you see the world.
In most cases, yes, polarized sunglasses are better.
They can block distracting glare, reduce reflections and make a sunny day look like it belongs on a postcard.
However, as you’ve seen, there are a few scenarios when they don’t work as well.
It all depends on how you plan to use them, and it’s not uncommon for people to own a polarized pair for some situations and non-polarized, “regular” sunglasses for others.
If you’ve never tried these sunglasses, consider a quick trial run at your local optical store — ideally on a sunny day. Look around the store and out the window. Where do you see the biggest differences in clarity and vibrancy? The sky, the car windshields, the roads?
