Since the last couple of years, polarized sunglasses have become a real alternative to traditional sunglasses and this change in trend can be credited to the aesthetically appealing designs of polarized sunglasses, but the fact of the matter is that these glasses are more than just good looking accessories to fashionable attire. Some of their advantages over traditional sunglasses makes them highly recommended by optometrists.

The sun has a surprising capacity to animate and brighten people’s day, however, no matter how beautiful it may seem, the light from the sun is harmful to our eyes mostly because of them being ultraviolet in nature. Without taking the proper precautions, the spectrum of visible light mixed with solar radiation can lead to devastating consequences for ocular health. This is where polarized sunglasses come into the conversation.

The best way to avoid a vision problem is to wear sunglasses with appropriate filters that repel the ultraviolet rays. In recent years, the traditional sunglasses have been replaced with the popular polarized sunglasses and that too for the right reasons. The path to ostracism for the traditional sunglasses has revealed their lack of improvement in both the performance and technological department, another reason why it is crucial to discuss the pros and cons of polarized sunglasses.

Polarized glasses are not something new since we have witnessed many athletes wearing them for years now. However, it was until a few summers ago when they became fashionable, making them a must-have accessory to anyone’s outfit regardless of whether it’s for business or casual

Beyond the aesthetic aspect of these products, are polarized glasses best for our visual health? Let’s find out.

What are the benefits of wearing polarized sunglasses?

A simple optometry class is the best way to start our debate for why any polarized sunglasses are better for your visual health. 

Since sunlight does not have a fixed direction, it has a high tendency to scatter across any medium. The problem arises when it bounces on a horizontal surface, be it the sea, the road, a ski track or a track. In this case, what we say is that a reflex is produced (a blinding light that is the result of the shock that goes directly to our eyes). Drivers are amongst the most common folk that face this tough battle with the sun, which often than most time ends with significant eye fatigue.

Polarized sunglasses act against the reflected light and block it, allowing a visual sharpness and clarity far superior to traditional glasses. Thanks to the nine or even ten layers that make up its crystals, polarization makes sure that your eyes can get adjusted to any sources of light without the need for additional precautions. Its use is recommended mainly to alleviate the rebound of sunlight on horizontal surfaces, a problem solver that comes with a price of its own depending on the design and designer you’re going for.

Therefore, if you practice outdoor sports or if you tend to drive a lot, polarized glasses should be your number one go-to accessory. Even if you are just in the mood to relax on a beach somewhere, polarized sunglasses achieve a much more natural and comfortable view of the horizon (Hawaii, I miss you). 

Its greater protection and performance against the effects of the reflections of light makes it the best option for those with high sensitivity to light. If you have vision problems bugging you, don’t worry; polarized sunglasses can be graduated and even progressive.

7 Advantages of polarized glasses

1. They eliminate reflections caused by the light from the sun.
2. They give greater clarity and contrast.
3. Total protection against UV rays.
4. With the polarizing filter, colors have a more natural aspect.
5. Reduces eye fatigue significantly.
6. They are more suitable for people with high sensitivity to light.
7. They are very versatile – They are allowed to add the appropriate graduation of myopia, hyperopia and/or astigmatism and incorporate progressive or photochromic lenses.

Disadvantages

Although these glasses are the recommended option in most situations, they do not always work well when it comes to artificial lighting. Since they are not designed to differentiate between other types of light, such as the ones from LCD screens, their filters will make you see everything too dark. 

No inconveniences though they have limitations. The graduation must be very high, an unusual circumstance among the population. In addition, the LCD screens are in progressive disuse, and the vertical reflections are much smaller in number than the horizontal ones. More care should be taken not to tilt the head at an angle greater than 45 degrees.

Are polarized sunglasses expensive?

It has always been said that polarized sunglasses are expensive, but in recent years the distance has been matched, and now the price depends more on the design or on the brand than the polarized technology itself. Despite this, many people still choose to get polarized models from places other than an optical or specialty store.

Always check if your sunglasses are polarized

How many places do you know that sell polarized glasses? Are they even polarized or are they just saying that to sell their sunglasses?

the difference between polarized and non-polarized filter is astounding.

Well, there are effortless ways to find out if the glasses you purchased are polarized:

  • The letter P on the lens or the word Polarized on one of the rods/temples of the glasses.
  • Find a reflective surface that produces glare when light is shining on it. You could use a reflective tabletop, a mirror, or other shiny, flat surface. Make sure the glare is noticeable even from about 2 to 3 feet (60 to 90 cm) away. [1]
  • Hold your sunglasses about 6 to 8 inches (15 to 20 cm) in front of your eyes. You should be able to view the surface through one of the lenses at a time. [2]
  • Rotate the sunglasses upwards to a 60-degree angle. Your sunglasses should be on an angle at this point, with one of the lenses raised slightly higher than the other. Since sunglasses are polarized in a specific direction, rotating the sunglasses can make the polarization more effective.

Are polarized sunglasses worth it?

In addition to being very comfortable when you wear them on the beach or during any sporting activity, polarized sunglasses are ideal for driving on wet roads or when we the sun is shining the brightest. They are also very useful for skiing since snow reflects sunlight horizontally (dangerous enough to throw you off your feet.)

Sometimes safety and comfort are more important than style, but even if you’re going for a designer brand, it never hurts to wear a beautiful pair of sunglasses whenever you’re enjoying the great outdoors.
