Five Ways Polarized Lenses Can Improve Your Eyeglass Experience

When choosing between a standard sunglass lens and a polarized lens, consider the extra protection that polarized lenses offer your eyes when designing your next pair of sunglass lenses.

The technology behind polarized lenses is just as interesting as the reasons for choosing these lenses in the first place. Polarized lenses were first invented by NASA scientists to help protect astronauts eyes when they went up into space. These scientists studied the design of an eagle’s eye to understand how they reflected glare, giving the glasses the original name of Eagle Eye Sunglasses.

This NASA technology has been adapted for lenses to help protect your eyes. Polarized filters are put over the lenses that work to absorb light reflected off of horizontal surfaces. This horizontal light, also known as glare, is dangerous for the long term health of your eye. This polarized filter helps you see better when you’re driving or working somewhere with direct sunlight.

From a technical perspective, the polarized filters create an opening that only allows vertical light rays (not the horizontal light waves reflected off surface) to get through. This filtration blocks out any potential glare, allowing you to see clearly when normal glasses would give you a glare.

The polarized lens technology is an easy choice if you’re looking for less glare and more protection with your new lenses. You can shop our polarized lenses online at Replacement Lens Express.

WHY CHOOSE POLARIZED LENSES? 

While NASA technology in your sunglasses sounds awesome, there are also some great reasons to choose polarized lenses when you build your new lenses on our website!  

They are better for your eyes.

Polarized lenses protect your eyes from dangerous UV rays. For the same reason you’re not supposed to stare directly at the sun, UV rays are harmful for your eyes. Constant exposure to UV rays can cause macular degeneration, vision loss, and other eye problems later in life. Cutting down the amount of exposure your eyes have to these UV rays will help keep your eyes healthy and strong.

With polarized lenses, you don’t need to add an extra UV coating to your sunglasses. Instead, this UV protection is an added benefit of choosing polarized lenses.

Filters Blue Light

The filtration on polarized lenses also blocks blue light, a wavelength that works to keep us awake and alert throughout the day. Most of our exposure to blue light comes from staring at computer and phone screens, but at night, the blue light can disrupt your circadian rhythm. To help balance your circadian rhythm, researchers are recommending filtering out blue light at night (or reducing screen time).

While other lenses, like our clear EyeZen technology, can help reduce eye strain and protect your eyes when you’re inside or staring at a computer screen, polarized lenses will reduce your exposure to blue light when you’re outside.

Reduces Glare

The polarized lenses prevent intense sunlight rays from getting to your eyes, eliminating glare when you’re outside. This glare reduction keeps you safe while driving during the day and keeps your eyes on the road.

Whether you are a morning commuter, athlete, or outdoor enthusiast, the glare reduction provided by polarized lenses will give you the best advantage regardless of what activity you’re doing. But if you wear eyeglasses more than sunglasses, anti-glare coatings like the Crizal SunShield can also give you the same protection from glare with your eyeglasses.

Enhances colors

When compared to non-polarized lenses, polarized lenses can make everything look darker. However, this filtration and lack of glare can also make those objects look clearer because your eye no longer sees those horizontal light reflections.  

But by filtering out the glare, colors look more vibrant and objects look more clear. With your polarized lenses, you’ll always have a breathtaking view with no glare blocking your vision.

They come in a variety of colors

When you add polarized lenses to your sunglasses, you can choose from a variety of different colors. From the more traditional brown, grey, or green, to more vibrant colors like copper, amber, sunflower, rose, and ocean, you can pick a color that makes a bold statement and matches your favorite frames.

WHY POLARIZED LENSES OVER TINTED LENSES? 

When you’re choosing lenses for your sunglasses, it can be hard to choose between polarized or tinted lenses.

Tinted sunglasses help with different things, depending on the tint of the glasses. For example, yellow tints can increase visibility with fog while darker tints can help motorcyclists and commuters filter out sunlight during long drives.

As we mentioned earlier, the technology behind polarized lenses blocks all horizontal light reflected off surfaces. This is handy for someone who doesn’t need to see those reflections and wants to protect their eyes.

What to see what this means? Here’s a test you can do to both verify that a frame has polarized lenses and better understand the technology for yourself.

  1. Take two pairs of sunglasses with polarized lenses
  2. Holding both pairs out, tilt one pair to a 90-degree angle.
  3. Overlap the lenses on both sunglasses

When these lenses are overlapped, you should see black. This is because you’ve inverted the horizontal technology so you are now blocking out all glare from light.

When you do this same test with tinted sunglasses, you won’t get the same effect. But tinted lenses are better for someone who doesn’t want to filter out intense sunlight, including pilots and skiers who need the light to perform.

Tinted and polarized lenses provide different kinds of options for your sunglasses. But with eye protection, blue light and glare filtration, color enhancement, and color options, polarized lenses offer many improvements for your eyeglass experience.
