How do Polarized Sunglasses Work In This Era?




Want create site? Find Free WordPress Themes and plugins.

If you have ever made use of polarized sunglasses, you might be eager to know their work. Nowadays, in the technological and digital era, these sunnies play a vital role by protecting from harmful UV sun rays. 

However, this type of shade is the premiere selection for outdoor enthusiasts. It is the better choice for those who live on the water, fishing, boating, and more. In addition, those activities demand the clearest vision from their sunglasses.

The primary benefit of polarized lenses is that they reduce glare. The glare effect is created when sunlight reflects from a flat surface, and the light is reflected in every direction. 

Ordinary tinted sunnies do not block glare; they reduce the brightness level of horizontal and vertical light. However, you have experienced glare or blinding light while outside, which can often impair your vision and cause discomfort.

In some cases, like driving, the glaring light is dangerous. In addition, you can protect your eyes and vision from this harmful glare by wearing designer eyewear. We know that sunlight is scattered in all directions.

In contrast, when it hits a flat surface, light is reflected and becomes polarized. It means the light is more concentrated and travels in a horizontal direction. Hence, this intense light can cause blinding glare and reduce your visibility. 

Therefore, these lenses are designed to shield your vision. In addition, it is an excellent way if you spend a lot of time outdoors or on the road. Now, let us discuss the working of polarized sunglasses in this digital world.

Precise Working Of Polarized Sunglasses

Polarized shades mitigate glare by using a chemical film either applied to or embedded in the lenses. The chemical filter on these sunnies removes glare by absorbing the incoming horizontal light, allowing vertical light to pass.

However, we perceive the glare as it usually reflects horizontal light. The horizontal light creates the effect of glare that is absorbed and nullified by the chemical film on lenses. 

These lenses only allow in vertical light, acting as a chemical blind. Although, light can reflect from different flat surfaces, including snow, water, cars, and roads. It is difficult for us to see when light is reflected and travels in a horizontal direction.

The unique filter in polarized sunglasses blocks out the intense glare. It follows and allows only vertical light to enter your eye. These lenses also offer enhanced colour perception to tinted lenses, making it easier to see in bright light conditions.

This situation is critical to maintaining healthy eyes and vision. So, while wearing these lenses, you may notice a rainbow effect on car windows. Moreover, the pattern you see in a rear car window is the strain pattern from the tempering process.

Similarly, when you wear polarized designer eyewear, you can find subtle dots or lines on rear car windows. In addition, these are sections of the glass that partially polarized light on a horizontal axis.

Since these lenses have a vertical axis, that light is blocked. It is the primary reason behind the appearance of dark dots or lines. Moreover, it is essential to have two polarized filters that are perpendicular to each other.

In contrast, one filter traps light travelling vertically and the other traps light travelling horizontally. The final result of this is that nothing gets through the combined filters. Therefore, it does not affect your clarity of vision.

We know that light waves from the sun vibrate in all directions. Also, it gets aligned in one direction when it is reflected from the flat surface. 

Example of knuckleball to understand a polarizing phenomenon

One way to understand the polarization process is to think of light like a knuckleball. When it leaves the pitcher’s hand, the ball is travelling in one trajectory. But, it is weaving and bouncing up and down along with the left and right sides. 

However, it is erratic and looks like a bundle of unpredictable energy. In contrast, the bat connects solidly; the ball will go soaring back out. Afterwards, it spins gracefully without any of that erratic motion.

In the same manner, light that is reflected from a horizontal surface loses its erratic motion. Hence, it travels in one concentrated beam in a horizontal movement. Therefore, we perceive it as a glare. 

Now, let us step away from reality for a moment but still use a baseball metaphor. You can imagine that the ball that was hit by the batter is traveling in one direction. But now, it moves forward and weaves from side to side. 

After, it is fast coming up on the outfield fence, which is a series of vertical bars. When the ball approaches, weaving left and right, it bounces from the vertical fence posts. It is because there is no way it can pass through moving in a zig-zag horizontal line.

Suppose the same ball travels in a vertical line by moving up and down. It could easily pass through the gaps in the fence because it is in the exact alignment with bars. However, this vertical fence is the polarizing filter in your sunglasses.

When the polarization axis is vertical, all light that has been polarized through reflection is traveling horizontally. This horizontal light will get blocked by the filter. It cannot pass through because it is moving in the opposite direction of the filter.

Similarly, any non-polarized light moving in multiple directions will become polarized after passing through the filter. So, again, it will block the horizontal light, and the vertical light will pass through.


Here, we have discussed the precise working of these lenses in this digital and technological world. You will get to know about the entire polarizing phenomenon and the effects of glare on your eyes. Furthermore, get crucial information about the importance of the chemical or polarizing filter used to remove glare.

What is the Difference Between a Digital Marketing Agency and a Company?




Want create site? Find Free WordPress Themes and plugins.

Digital marketing has become an essential part of business growth strategies over the past decade. As technologies evolve and consumer behaviors change, companies require expert guidance to navigate this dynamic online landscape. This is where digital marketing agencies come in. However, what exactly makes an agency different from an in-house digital marketing team or company?

Let’s break down the key differences between a digital marketing agency and a company to help you determine the best partner for your business goals.

Core Functions

A digital marketing agency’s core function is to provide marketing and advertising services to external clients. Their expertise lies in managing digital campaigns, projects, and programs on behalf of various companies across different industries.

On the other hand, a company’s core function is to produce, distribute, and sell its products or services. While some large companies may have dedicated in-house digital teams, the primary focus remains on their core offering rather than acting as an agency for other businesses.

Specialized Skills and Services

Agencies employ specialists across various digital marketing disciplines like search engine optimization (SEO), paid search, social media marketing, email marketing, web design and development, content creation, analytics, and more.

They have deep experience and proprietary strategies for each channel. Agencies also stay up to date with the latest marketing technologies and trends to offer tailored solutions.

Companies may have generalists handling digital tasks but lack some of the specialized expertise agencies possess. Outsourcing to an agency allows companies to tap into a wider range of skills.

Resources and Scale

Agencies have dedicated resources, large teams, specialized tools, and economies of scale from serving multiple clients simultaneously. This allows them to efficiently execute campaigns on a broad scope.

For a single company, maintaining such resources in-house would require a substantial budget and headcount which may not always be feasible or cost-effective compared to outsourcing certain activities.

Objective Viewpoint

As external partners, agencies can provide an unbiased perspective on a company’s brand, products, target audiences, and competitive landscape. They analyze metrics with impartiality to spot growth opportunities the company may miss internally.

Internal teams working for their own company may have subjective views colored by various factors within the organization. Agencies offer a more objective third-party viewpoint.

Brand Independence

Agencies are not tied to any single brand or industry which gives them flexibility to experiment with diverse strategies. Their reputation and success depend on delivering results across clients rather than pushing their products.

Companies are constrained by their proprietary brand identity, messaging, and offerings. Testing new unproven approaches may introduce potential risks to the core business model. Agencies mitigate such challenges for client brands.

Cost Structure

For companies, setting up and maintaining specialized in-house digital teams requires large fixed capital expenditures on infrastructure, tools, staff salaries, etc. This may strain resources, especially for smaller and medium businesses.

Agencies operate on a variable cost structure, charging mainly for services delivered. This subscription model passes on setup and overhead costs across multiple clients, keeping pricing economical for companies of all sizes on a pay-as-you-go basis.

Common FAQs

Q. How do I decide between an agency or an in-house team?

A. Consider your goals, budget, required expertise, and desired level of accountability. Agencies are best for periodic projects or channel-specific needs. In-house works better for core business functions and long-term brand-building activities.

Q. What should I look for in a good digital marketing agency partner?

A. Expertise in your industry, proven success track record, transparent communication, dedicated account management, technology integrations, and focus on KPI-based performance. Good cultural fit is also important for long-term collaboration.

Q. How do agencies charge for their services?

A. Most agencies operate on monthly retainer fees or project-based payments. Some also charge hourly rates. Expect additional costs for pay-per-click ads, advanced tools, etc. Agree on payment structure and deliverables upfront to avoid scope creep issues later.

Q. How can a company leverage both options for best results?

A. Use agencies for specialized services like SEO, paid media buying, etc. Manage core messaging, content, and analytical functions in-house. Review progress together to gain from an external perspective while retaining brand control internally.

In conclusion, both digital marketing agencies and in-house teams have pros and cons depending on a company’s short and long-term goals. Leveraging specialized agency expertise alongside internal stewardship of key functions provides the optimal approach for most organizations seeking to maximize growth in today’s digital landscape. Outsourcing non-core activities to reputed professionals allows companies to stay agile and stay focused on their core offerings.
